+This document details the changes between this version, bash-5.2-rc3, and
+the previous version, bash-5.2-rc2.
+
+1. Changes to Bash
+
+a. Added a compatibility mode feature that causes the parser to parse command
+   substitutions as if extglob were enabled. If it is enabled before execution,
+   parse at execution will succeed. If not, the subsequent execution parse will
+   fail.
+

+   trap is executed while running in a shell function.
+
+2. Changes to Readline
+
+3. New Features in Bash
+
+4. New Features in Readline
+
+a. Readline now checks for changes to locale settings (LC_ALL/LC_CTYPE/LANG)
+   each time it is called, and modifies the appropriate locale-specific display
+   and key binding variables when the locale changes.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-5.2-rc2, and
+the previous version, bash-5.2-rc1.
+
+1. Changes to Bash
+
+a. Fixed a bug that could disable history saving after a compound array
+   assignment in an interactive shell.
+
+b. Fixed a bug that could cause incorrect error messages when running a DEBUG
+   trap during a conditional or arithmetic command.
+
+c. Fixed a bug that caused test to print an error message when given ! ! arg
+   as arguments.
+
+d. Fixed a bug that resulted in incorrect error messages when completing a
+   backquoted command substitution.
+
+e. Changed command substitution parsing to reproduce the original text more
+   closely when reconsituting the command string from the parsed command.
+
+f. Fixed a bug that could cause an EXIT trap to use the wrong variable context
+   when the errexit option is set.
+
+g. Fixed a bug that could cause the parser to incorrectly delimit a token when
+   an alias expansion ended with a multibyte character.
+
+2. Changes to Readline
+
+3. New Features in Bash
+
+a. Since there is no `declare -' equivalent of `local -', make sure to use
+   `local -' in the output of `local -p'.
+
+b. Null anchored matches in pattern substitution now process `&' in the
+   replacement string, like sed.
+
+4. New Features in Readline
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-5.2-rc1, and
+the previous version, bash-5.2-beta.
+
+1. Changes to Bash
+
+a. Changes to `wait -p' and how it sets the variable name in the presence of
+   valid and invalid PID arguments.
+
+b. Fixed a bug that caused compgen to dump core if the completion engine was
+   not initialized.
+
+c. Fixed a memory leak in the variable name programmable completion code.
+
+d. Here-documents and here-strings use tempfiles if the shell compatibility
+   level is 50 or lower.
+
+e. Non-interactive shells exit on a syntax error encountered while parsing a
+   command substitution.
+
+f. Fixed a bug with inherited parser state while parsing a command substitution.
+
+g. Fixed a bug that caused the shell not to check for terminating signals
+   after executing the command_string supplied with `-c' and before executing
+   the exit trap.
+
+h. Changes to avoid a make race condition while generating builtins.c.
+
+i. Make it explicit that BASH_REMATCH is always a global variable, and that
+   local copies are (currently) ignored.
+
+j. Fixed a bug that caused an ambiguous redirection (>&word) to be printed
+   incorrectly (>&word) if no file descriptor was supplied.
+
+2. Changes to Readline
+
+a. Fixed a bug that caused rl_eof_found to be set prematurely while reading a
+   multi-character key sequence in callback mode.
+
+3. New Features in Bash
+
+a. In posix mode, the `printf' builtin checks for the `L' length modifier and
+   uses long double for floating point conversion specifiers if it's present,
+   double otherwise.
+
+b. The `globbing' completion code now takes the `globstar' option into account.
+
+c. `suspend -f' now forces the shell to suspend even if job control is not
+   currently enabled.
+
+4. New Features in Readline
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-5.2-beta, and
+the previous version, bash-5.2-alpha.
+
+1. Changes to Bash
+
+a. Fixed a problem with command-oriented history and multi-line commands that
+   caused embedded blank lines to be run together.
+
+b. Changed the way `&' is quoted when performing pattern substitution and
+   `patsub_replacement' is enabled.
+
+c. Fixed some integer overflows when expanding strings or reading the output
+   of command substitution larger than 2GB.
+
+d. `wait -p' without the `-n' option now does something useful if there are no
+   jobs.
+
+e. Fixed an issue with read timeouts in posix mode.
+
+f. Changed here-document processing to process $'...' and $"..." only when they
+   appear in the WORD portion of ${PARAM OP WORD} in the here-document body
+   and the body is being expanded.
+
+g. Changed alias expansion in command substitution to be posix-conformant
+   (performed while initially parsing the command substitution) when in posix
+   mode.
+
+h. Bash optimizes away more forks in subshells.
+
+i. Here-document construction now performs quote removal on the here-document
+   delimiter only if it's marked as quoted, which prevents quote characters in
+   command substitutions from being removed.
+
+j. Prompt string expansion now gives invisible characters in the expansion of
+   the \w, \W, and \s escape sequences a visible representation to avoid
+   problems with redisplay.
+
+k. Fixed a problem with SIGINT during the execution of a command bound with
+   `bind -x' affecting the saved terminal settings.
+
+l. Fixed an inconsistency with how $@ expands in a construct like ${@:+set}
+   or ${array[@]:+set} in the presence of null positional parameters or
+   array elements.
+
+2. Changes to Readline
+
+a. Prevent some display problems when running a command as the result of a
+   trap or one bound using `bind -x' and the command generates output.
+
+b. Fixed an issue with multi-line prompt strings that have one or more
+   invisible characters at the end of a physical line.
+
+c. Fixed an issue that caused a history line's undo list to be cleared when
+   it should not have been.
+
+3. New Features in Bash
+
+a. There is a new bindable readline command name: `vi-edit-and-execute-command'.
+
+4. New Features in Readline
+
+a. Two new bindable string variables: active-region-start-color and
+   active-region-end-color. The first sets the color used to display the
+   active region; the second turns it off. If set, these are used in place
+   of terminal standout mode.
+
+b. New readline state (RL_STATE_EOF) and application-visible variable
+   (rl_eof_found) to allow applications to detect when readline reads EOF
+   before calling the deprep-terminal hook.
+
+c. There is a new configuration option: --with-shared-termcap-library, which
+   forces linking the shared readline library with the shared termcap (or
+   curses/ncurses/termlib) library so applications don't have to do it.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-5.2-alpha, and
+the previous version, bash-5.1-release.
+
+1. Changes to Bash
+
+a. Fixed a bug that assigned a value to the variable name supplied as an
+   argument to `wait -p' when there were no jobs.
+
+b. Fixed a bug that resulted in performing incorrect word expansion on the
+   key/value pairs in a compound array assignment.
+
+c. Fixed a bug that could put the child forked to run a command substitution
+   into the wrong process group.
+
+d. Fixed a problem that could cause the lastpipe option to work incorrectly if
+   file descriptor 0 was closed.
+
+e. Bash tries to suppress traps if a forked child receives a trapped signal
+   before it has a chance to reset its signal handlers.
+
+f. Fixed several memory leaks in compound array assignments.
+
+g. Fixed a problem with performing an assignment with `+=' to an array element
+   that was the value of a nameref.
+
+h. Fixed a bug that could cause a nameref containing an array reference using
+   `@' or `*' not to expand to multiple words.
+
+i. Fixed a bug where extended glob functions could match `.' or `..' when it
+   wasn't explicitly specified, even if dotglob was set.
+
+j. Fixed a bug that caused non-interactive posix-mode shells not to exit on a
+   variable assignment error while assigning into the temporary environment.
+
+k. Fixed a bug that caused parsing errors if an alias contained a compound
+   array assignment.
+
+l. Fixed a couple of instances where bash checked syntax too aggressively when
+   trying to determine how to add a partial command to command-oriented
+   history.
+
+m. Fixed a parser problem that caused it not to allow reserved words to follow
+   the `((' and `[[' commands.
+
+n. Fixed a bad offset calculation when using negative offsets to `history -d'.
+
+o. Fixed an off-by-one error that caused a read past the end of a buffer when
+   reading a multibyte character from the output of a command substitution.
+
+p. Fixed a problem with a failed `exec' command not setting $? to the right
+   value for an exit trap.
+
+q. Fixed a problem that caused bash not to unlink FIFOs created as part of
+   expanding redirections for an external command.
+
+r. Fixed a bug that could cause aliases not to be expanded in case statements.
+
+s. Fixed a bug that could cause word completion to attempt programmable
+   completion for the target of a redirection, instead of filename completion.
+
+t. Fixed a bug that could result in errors after rebinding a key sequence with
+   `bind -x' multiple times.
+
+u. Fixed a problem that could result in not quoting the result when performing
+   command name completion with a glob pattern in the command name.
+
+v. `mapfile' now uses fully-buffered reads in more cases, which should improve
+   bulk read performance.
+
+w. Fixed a bug that caused `wait -n' to not reset its internal state when
+   interrupted by a signal, resulting in subsequent calls failing.
+
+x. Fixed a bug with parsing numeric arguments to readline key sequences
+   installed with `bind -x'.
+
+y. Bash suppresses forking in several additional cases, including most uses
+   of $(<file).
+
+z. If there are multiple `!' tokens in a [[ command, toggle the invert state
+   instead of setting it unconditionally.
+
+aa. Fixed a bug where running `fc' on an empty history list would cause the
+    shell to crash.
+
+bb. Word completion now checks whether or not a quote character closes a
+    quoted string begun on a previous line, so readline doesn't interpret the
+    quote as starting a new quoted string.
+
+cc. Fixed a typo that translated \UNNNNNNNN characters that were not valid in
+    the current locale encoding as \uNNNNNNNN.
+
+dd. Fixed an issue that could cause bash to print timing statistics for the
+    wrong command when `set -e' causes a command to fail.
+
+ee. Bash now runs the exit trap in function context if a failed command in
+    the function causes the shell to exit.
+
+ff. Some fixes to how subshells modify $SHLVL.
+
+gg. Fixed a bug that caused `mapfile -t' not to remove the delimiter when the
+    delimiter is > 128 in the current encoding.
+
+hh. Fixed a problem that could cause the shell to attempt to free unallocated
+    memory if an expansion error occurred.
+
+ii. Fixed a bug in the bash malloc implementation of malloc_usable_size. Bash
+    did not use it, but it could cause problems with library functions that
+    did.
+
+jj. If the `exec' builtin fails, and the shell does not exit, it restores
+    trapped signals to their trapped state.
+
+kk. Fixed a bug that could cause variable assignment arguments to `declare' to
+    expand variables using attributes that the call to declare was turning off.
+
+ll. Fixed a bug with LINENO and arithmetic for commands.
+
+mm. Fixed a posix-mode bug that caused tildes not to be expanded after an
+    unquoted colon on the right side of an assignment statement.
+
+nn. Fixed a problem with `caller' and line numbers when executing an ERR trap.
+
+oo. Fixed a problem that could make the value returned by ${a:=b} not be the
+    final value assigned to a (e.g., if `a' has an attribute that modifies
+    the value on assignment).
+
+pp. Fixed a problem with saving multi-line here-documents to the history list
+    where the here-document delimiter does not appear on the first line.
+
+qq. Fixed a bug with using += to assign to dynamic variables like RANDOM.
+
+rr. Fixed a bug that caused `set -n' to modify $? if set after execution had
+    started.
+
+ss. Builtins like printf/read/wait now behave more consistently when assigning
+    arbitrary keys to associative arrays (like `]'. when appropriately quoted).
+
+tt. Fixed a problem with here-document collection printing the wrong prompt
+    when parsing a compound list in an interactive shell.
+
+uu. Fixed a problem with quoting shell expansion characters (like `$') when
+    they appear in a tab-completed word along with characters that do need
+    quoting (e.g.. $HOME/VirtualBox VMs).
+
+2. Changes to Readline
+
+a. Fixed a problem with cleaning up active marks when using callback mode.
+
+b. Fixed a problem with arithmetic comparison operators checking the version.
+
+c. Fixed a problem that could cause readline not to build on systems without
+   POSIX signal functions.
+
+d. Fixed a bug that could cause readline to crash if the application removed
+   the callback line handler before readline read all typeahead.
+
+e. Added additional checks for read errors in the middle of readline commands.
+
+f. Fixed a redisplay problem that occurred when switching from the digit-
+   argument prompt `(arg: N)' back to the regular prompt and the regular
+   prompt contained invisible characters.
+
+g. Fixed a problem with restoring the prompt when aborting an incremental
+   search.
+
+h. Fix a problem with characters > 128 not being displayed correctly in certain
+   single-byte encodings.
+
+i. Fixed a problem with unix-filename-rubout that caused it to delete too much
+   when applied to a pathname consisting only of one or more slashes.
+
+j. Fixed a display problem that caused the prompt to be wrapped incorrectly if
+   the screen changed dimensions during a call to readline() and the prompt
+   became longer than the screen width.
+
+k. Fixed a problem that caused the \r output by turning off bracketed paste
+   to overwrite the line if terminal echo was disabled.
+
+l. Fixed a bug that could cause colored-completion-prefix to not display if
+   completion-prefix-display-length was set.
+
+m. Fixed a problem with line wrapping prompts when a group of invisible
+   characters runs to the right edge of the screen and the prompt extends
+   longer then the screen width.
+
+n. Fixed a couple problems that could cause rl_end to be set incorrectly by
+   transpose-words.
+
+3. New Features in Bash
+
+a. The bash malloc returns memory that is aligned on 16-byte boundaries.
+
+b. There is a new internal timer framework used for read builtin timeouts.
+
+c. Rewrote the command substitution parsing code to call the parser recursively
+   and rebuild the command string from the parsed command. This allows better
+   syntax checking and catches errors much earlier. Along with this, if
+   command substitution parsing completes with here-documents remaining to be
+   read, the shell prints a warning message and reads the here-document bodies
+   from the current input stream.
+
+d. The `ulimit' builtin now treats an operand remaining after all of the options
+   and arguments are parsed as an argument to the last command specified by
+   an option. This is for POSIX compatibility.
+
+e. Here-document parsing now handles $'...' and $"..." quoting when reading the
+   here-document body.
+
+f. The `shell-expand-line' and `history-and-alias-expand-line' bindable readline
+   commands now understand $'...' and $"..." quoting.
+
+g. There is a new `spell-correct-word' bindable readline command to perform
+   spelling correction on the current word.
+
+h. The `unset' builtin now attempts to treat arguments as array subscripts
+   without parsing or expanding the subscript, even when `assoc_expand_once'
+   is not set.
+
+i. There is a default value for $BASH_LOADABLES_PATH in config-top.h.
+
+j. Associative array assignment and certain instances of referencing (e.g.,
+   `test -v') now allow `@' and `*' to be used as keys.
+
+k. Bash attempts to expand indexed and associative array subscripts only
+   once when executing shell constructs and word expansions.
+
+l. The `unset' builtin allows a subscript of `@' or `*' to unset a key with
+   that value for associative arrays instead of unsetting the entire array
+   (which you can still do with `unset arrayname'). For indexed arrays, it
+   removes all elements of the array without unsetting it (like `A=()').
+
+m. Additional builtins (printf/test/read/wait) do a better job of not
+   parsing array subscripts if array_expand_once is set.
+
+n. New READLINE_ARGUMENT variable set to numeric argument for readline commands
+   defined using `bind -x'.
+
+o. The new `varredir_close' shell option causes bash to automatically close
+   file descriptors opened with {var}<fn and other styles of varassign
+   redirection unless they're arguments to the `exec' builtin.
+
+p. The `$0' special parameter is now set to the name of the script when running
+   any (non-interactive) startup files such as $BASH_ENV.
+
+q. The `enable' builtin tries to load a loadable builtin using the default
+   search path if `enable name' (without any options) attempts to enable a
+   non-existent builtin.
+
+r. The `printf' builtin has a new format specifier: %Q. This acts like %q but
+   applies any specified precision to the original unquoted argument, then
+   quotes and outputs the result.
+
+s. The new `noexpand_translations' option controls whether or not the translated
+   output of $"..." is single-quoted.
+
+t. There is a new parameter transformation operator: @k. This is like @K, but
+   expands the result to separate words after word splitting.
+
+u. There is an alternate array implementation, selectable at `configure' time,
+   that optimizes access speed over memory use (use the new configure
+    --enable-alt-array-implementation option).
+
+v. If an [N]<&WORD- or [N]>&WORD- redirection has WORD expand to the empty
+   string, treat the redirection as [N]<&- or [N]>&- and close file descriptor
+   N (default 0).
+
+w. Invalid parameter transformation operators are now invalid word expansions,
+   and so cause fatal errors in non-interactive shells.
+
+x. New shell option: patsub_replacement. When enabled, a `&' in the replacement
+   string of the pattern substitution expansion is replaced by the portion of
+   the string that matched the pattern. Backslash will escape the `&' and
+   insert a literal `&'.
+
+y. `command -p' no longer looks in the hash table for the specified command.
+
+z. The new `--enable-translatable-strings' option to `configure' allows $"..."
+   support to be compiled in or out.
+
+aa. The new `globskipdots' shell option forces pathname expansion never to
+    return `.' or `..' unless explicitly matched. It is enabled by default.
+
+bb. Array references using `@' and `*' that are the value of nameref variables
+    (declare -n ref='v[@]' ; echo $ref) no longer cause the shell to exit if
+    set -u is enabled and the array (v) is unset.
+
+4. New Features in Readline
+
+a. There is now an HS_HISTORY_VERSION containing the version number of the
+   history library for applications to use.
+
+b. History expansion better understands multiple history expansions that may
+   contain strings that would ordinarily inhibit history expansion (e.g.,
+   `abc!$!$').
+
+c. There is a new framework for readline timeouts, including new public
+   functions to set timeouts and query how much time is remaining before a
+   timeout hits, and a hook function that can trigger when readline times
+   out. There is a new state value to indicate a timeout.
+
+d. Automatically bind termcap key sequences for page-up and page-down to
+   history-search-backward and history-search-forward, respectively.
+
+e. There is a new `fetch-history' bindable command that retrieves the history
+   entry corresponding to its numeric argument. Negative arguments count back
+   from the end of the history.
+
+f. `vi-undo' is now a bindable command.
+
+g. There is a new option: `enable-active-region'. This separates control of
+   the active region and bracketed-paste. It has the same default value as
+   bracketed-paste, and enabling bracketed paste enables the active region.
+   Users can now turn off the active region while leaving bracketed paste
+   enabled.
+
+h. rl_completer_word_break_characters is now `const char *' like
+   rl_basic_word_break_characters.
+
+i. Readline looks in $LS_COLORS for a custom filename extension
+   (*.readline-colored-completion-prefix) and uses that as the default color
+   for the common prefix displayed when `colored-completion-prefix' is set.

+	  `assoc_expand_once' option were enabled.
+	- the expressions in substring parameter brace expansion can be
+	  expanded more than once
+	- the expressions in the $(( ... )) word expansion can be expanded
+	  more than once
+	- arithmetic expressions used as indexed array subscripts can be
+	  expanded more than once;
+	- `test -v', when given an argument of A[@], where A is an existing
+	  associative array, will return true if the array has any set
+	  elements. Bash-5.2 will look for a key named `@';
+	- the ${param[:]=value} word expansion will return VALUE, before any
+	  variable-specific transformations have been performed (e.g.,
+	  converting to lowercase). Bash-5.2 will return the final value
+	  assigned to the variable, as POSIX specifies;
+	- Parsing command substitutions will act as if extended glob is
+	  enabled, so that parsing a command substitution containing an extglob
+	  pattern (say, as part of a shell function) will not fail. This
+	  assumes the intent is to enable extglob before the command is
+	  executed and word expansions are performed. It will fail at word
+	  expansion time if extglob hasn't been enabled by the time the
+	  command is executed.

-builtins/printf.def
-	- bexpand: if passed a null or empty string, return a newly-allocated
-	  empty string (so the return value can always be freed) instead of
-	  NULL.
-	- printstr: if passed a null string, treat it as if it were an empty

+builtins/wait.def
+	- wait_builtin: don't assign the variable given with -p if there are no

 arrayfunc.c
-	- unbind_array_element: now takes a third (flags) argument; flags&1
-	  means to not expand an associative array index. This is only called
-	  from a shell builtin context, which means the argument should have
-	  already undergone word expansion, so it should be ok.  Will still
-	  be a problem for uses like "unset -v 'var[$ind]'", quoted to avoid
-	  globbing
-	- valid_array_reference: pass second flags argument to skipsubscript;
-	  still set to 0 by all callers
+	- kvpair_assignment_p: return non-zero if argument L appears to be a
+	  key-value pair associative array compound assignment
+	- expand_and_quote_kvpair_word: run a single word in a key-value pair
+	  associative array compound assignment through the appropriate
+	  expansions and single-quote the result
 
 arrayfunc.h
-	- unbind_array_element: updated prototype
+	- kvpair_assignment_p, expand_and_quote_kvpair_word: extern declarations
 
-builtins/set.def
-	- unset_builtin: add third argument of 1 to unbind_array_element calls
-	  [TEMPORARILY DISABLED]
-	- unset_builtin: call valid_array_reference with second arg of 1 to
-	  handle unmatched pairs of quotes and [/]
-
-array.c
-	- array_reference: optimize access locality as well as sequential
-	  access by adding ability to start from last-accessed element and move
-	  backwards or forwards depending on the desired index.  Inspired by
-	  report from Tom McCurdy <tom.j.mccurdy@gmail.com> and followup from
-	  Christian Franke <Christian.Franke@t-online.de>
-
-variables.c
-	- all_array_variables: include associative arrays, not just indexed
-	  arrays.  Reported by Grisha Levit <grishalevit@gmail.com>
-
-execute_cmd.c
-	- execute_disk_command: if we're optimizing out the fork (CMD_NO_FORK),
-	  decrement the shell level so we don't end up incrementing it twice.
-	  We should decrement the shell level for an implicit exec like an
-	  explicit one.  Reported by Stephane Chazelas
-	  <stephane.chazelas@gmail.com>
-
-builtins/exec.def
-	- exec_builtin: don't bother to decrement the shell level if we are
-	  already in a `(command)' subshell.  Reported by Stephane Chazelas
-	  <stephane.chazelas@gmail.com>
-
-lib/readline/macro.c
-	- macro_level: count of macro nesting level, maintained by
-	  _rl_push_executing_macro and _rl_pop_executing macro
-	- _rl_with_macro_input: if current nesting level exceeds
-	  MAX_MACRO_LEVEL, abort the current command line with _rl_abort_internal
-	  and return to the top level.  Reported by Christian Klomp
-	  <christianklomp@gmail.com>
-
-lib/readine/history.c
-	- add_history: if allocating the history list for the first time,
-	  make sure the max history list size isn't so large that it will
-	  cause allocation errors.  Cap it at MAX_HISTORY_INITIAL_SIZE
-	  (8192).  Reported by Sean Zha <freeman_cha@hotmail.com>
-
-jobs.c
-	- wait_for: if a foreground job with job control enabled is killed by a
-	  SIGINT and sourcelevel != 0, act as if we received the SIGINT so the
-	  file sourcing can be terminated.  Reported by PePa
-	  <peterkelly@passchier.net>
-
-				   9/26
-				   ----
 subst.c
-	- read_comsub: only warn once for null bytes in command substitution
-	  output, instead of once for every null byte
+	- expand_oneword: detect whether VALUE appears to be a key-value
+	  pair compound assignment and call the appropriate function to expand
+	  each word in the resulting list. Fixes inconsistency reported by
+	  oguzismailuysal@gmail.com
 
-arrayfunc.c
-	- array_variable_part: now takes a `flags' argument; changed all callers
-	  to initially pass 0
-	- array_variable_name: now takes a `flags' argument; changed all callers
-	  to initially pass 0
-	- array_variable_name: pass `flags' argument to skipsubscript instead
-	  of just passing 0
-
-arrayfunc.h
-	- array_variable_{name,part}: added new argument to prototypes
-
-				   9/29
-				   ----
-bashline.c
-	- bash_directory_completion_hook: don't bother to try and expand a
-	  ${ or $( that isn't complete; expand_prompt_string will complain.
-	  Fixes reports from John Passaro <john.a.passaro@gmail.com> and
-	  Valentin Bajrami <valentin.bajrami@gmail.com>
-
-lib/readline/history.c
-	- _hs_append_history_line: use a strategy that attempts to avoid
-	  realloc copying memory to a newly-allocated block if the history
-	  line we're appending to gets `too long' (currently 256 bytes).
-	  We reallocate in powers of 2 starting at 512, and rely on realloc
-	  not allocating a new block and copying into it if the size is the
-	  same as the last call to realloc.  Addresses issue raised by
-	  Hubert Schmid <h.schmid@gmx.de>
-
-trap.h
-	- check_signals: new extern declaration
-	- trapped_signal_received: new extern declaration
-
-builtins/read.def
-	- read_builtin: if one of the zread* functions returns < 0 (which
-	  usually only happens in Posix mode), make sure we call check_signals()
-	  before eventually calling run_pending_traps() because zread() isn't
-	  going to call it
-	- include trap.h for correct extern functions and variable declarations
-
-lib/sh/zread.c
-	- zread: if executing a builtin, call check_signals_and_traps() for
-	  backwards compatibility.  If not, call check_signals() only, because
-	  we don't want to run traps during, for instance, reading command
-	  substitution output.  Fixes race condition bug reported by Luiz Angelo
-	  Daros de Luca <luizluca@gmail.com>
-
-				   9/30
-				   ----
+				   12/12
+				   -----
 subst.c
-	- command_substitute: reset parse_and_execute_level to 0 in the child
-	  process, since it's independent of the other parse_and_execute
-	  calls.  Adds command substitution inside other parse_and_execute
-	  calls optimizations to suppress forks, as suggested by
-	  Martijn Dekker <martijn@inlv.org>
-
-				   10/3
-				   ----
-configure.ac
-	- SHOBJ_STATUS: make sure it defaults to unsupported and is substituted
-	  if the shobj-conf script isn't run.  Fixes `make install' bug with
-	  a minimal config reported by Andrew Tomazos <andrewtomazos@gmail.com>
-
-				   10/5
-				   ----
-support/shobj-conf
-	- darwin: set compatibility_version for a shared build of the readline
-	  library (the standalone readline distribution shares this file) to
-	  $(SHLIB_MAJOR)$(SHLIB_MINOR).  Recommendation from Max Horn
-	  <max@quendi.de>
+	- command_substitute: don't reset pipeline_pgrp to shell_pgrp if we
+	  are already forked to run a command (SUBSHELL_FORK). Fixes SIGINT
+	  in command substitution in here-document in forked child issue
+	  reported by oguzismailuysal@gmail.com
 
-				   10/6
-				   ----
-array.h
-	- array_first_index: new convenience define
-
-array.c
-	- ADD_AFTER: new define, complement of ADD_BEFORE
-	- UNSET_LASTREF: now takes an array as an argument, prepping for move
-	  of lastref pointer into the array struct
-	- array_insert: check whether we are adding at the beginning of the
-	  array and take a fast path if so
-	- array_insert: use same strategy as array_reference to find the place
-	  to insert, starting from the last-referenced element and moving
-	  forward or back from there; use ADD_AFTER if moving backward
-	- array_insert: if replacing an existing element, just replace the
-	  value with new->value instead of the entire element
-	- array_reference: short-circuit quickly if looking for an element
-	  before the first assigned index
-	- array_reference: if we don't find the element, leave lastref pointing
-	  to the closest element under the assumption we will be assigning or
-	  looking for something close
-	- array_reference: take advantage of ordered indexes to short-circuit
-	  when looking for element that is not set
-
-				   10/7
-				   ----
-array.c
-	- array_remove: short-circuit if asked to remove index after max
-	  index or before first index
-
-				   10/10
+				   12/18
 				   -----
-lib/malloc/malloc.c
-	- internal_realloc: if we are requesting reallocation to the same size
-	  as the block's current size, short-circuit and return `mem' right
-	  after doing bounds check
-	- internal_realloc: if we are reducing the size of an allocation, and
-	  the new size fits in the next lower bin, just keep the same block
-	  and adjust the size, so we can avoid some copies
-
-parse.y
-	- set_line_mbstate: keep track of the allocated size of
-	  shell_input_line_property, only request reallocation if the size
-	  increases, but don't let it get too big
+execute_cmd.c
+	- execute_pipeline: execute the lastpipe code even if prev == 0. It
+	  can only be 0 here if stdin was closed when this function was
+	  executed
+	- execute_pipeline: if prev == 0, set lstdin to a sentinel (-1) that
+	  means to close fd 0 after executing the command, and call close(prev)
+	  before restoring stdin. restore_stdin now understands -1, and closes
+	  fd 0. Fixes issue reported by Tomas Janousek <tomi@nomi.cz>

+				   12/21
 				   -----
-jobs.c
-	- wait_for_background_pids: make sure we wait for pid in
-	  last_procsub_child since it's not found in any job -- still needs
-	  more work to wait for multiple process substitutions
-
-subst.c
-	- process_substitute: if make_child fails, make sure we call
-	  restore_pipeline to undo the previous save_pipeline()
+doc/bashref.texi
+	- PROMPT_COMMANDS: clean up a couple of remaining instances of this
+	  name. Report from Eli Schwartz <eschwartz@archlinux.org>
 
-				   10/15
+				   12/26
 				   -----
 subst.c
-	- process_substitute,command_substitute: leave subshell_level (reflected
-	  as $BASH_SUBSHELL) intact for any exit trap instead of decrementing
-	  it.  Suggested by Martijn Dekker <martijn@inlv.org>
+	- command_substitute: make sure that the child process always has
+	  pipeline_pgrp == shell_pgrp: if pipeline_pgrp is non-zero when we
+	  get to the child, meaning that we're part of an already-forked
+	  child that is, for instance, running redirections, we need to reset
+	  shell_pgrp to it to preserve the invariant. Fixes bug with terminal
+	  being set to the incorrect pgrp reported by oguzismailuysal@gmail.com
 
-builtins/evalstring.c
-	- optimize_subshell_command: new function, framework for optimizing
-	  out forks for command that have already forked and are executing
-	  in a subshell. Not used yet
-
-expr.c
-	- readtok: if we have a post-increment or post-decrement, and the
-	  previous token is not a string, check whether the previous token is
-	  a number that results from a pre-increment or pre-decrement, and
-	  make that an error.  Report from Conrad Hoffmann <ch@bitfehler.net>
-
-				   10/16
-				   -----
-aclocal.m4
-	- BASH_JOB_CONTROL_MISSING: convert from AC_TRY_RUN to AC_TRY_COMPILE
-	  with existing set of preprocessor defines, so it can work when
-	  cross-compiling.  Suggested by Felix Janda <felix.janda@posteo.de>
-
-				   10/19

 				   -----
-variables.c
-	- get_bashpid: BASHPID is no longer readonly; assignments to it are
-	  just ignored.
+configure.ac,builtins/shobj-conf,m4/threadlib.m4
+	- midnightbsd: update auto-configuration to treat MidnightBSD like
+	  FreeBSD. From https://savannah.gnu.org/patch/?10006
 
-doc/{bash.1,bashref.texi}
-	- BASHPID: note that assignments are ignored and unsetting BASHPID
-	  causes it to lose its special properties
-
-				   10/28
+				   12/30
 				   -----
-builtins/pushd.def
-	- popd_builtin: make sure to check the normalized stack offset
-	  (i.e., negatives counting back from the end of the stack) is within
-	  bounds before trying to free that stack entry.  Report from
-	  Fernando Muñoz <fernando@null-life.com>
-

-	  command number or -2
-	- maybe_add_history: set current_command_line_comment for first line
-	  of command
-	- bash_add_history: chars_to_add set to "\n" if the current command line
-	  is one greater than the previous line containing a comment
-	  (current_command_line_comment).  Fixes complaint from back in
-	  January, 2016 from Dave Rutherford <dave@evilpettingzoo.com>
+examples/loadables/stat.c
+	- stattime: use strftime with a default format or the format supplied
+	  with the -F option to format the file time information
+	- stat_builtin: now takes a -F fmt option for a strftime format string;
+	  change to function calling sequences to pass the format down to

-array.h
-	- lastref: move last-referenced pointer into each array struct, so all
-	  arrays can have reference locality

-
-pathexp.c
-	- quote_string_for_globbing: if quoting for a regexp, make sure to
-	  skip and copy a leading `^' in a bracket expression, and skip and
-	  copy a subsequent `]' (after an optional `^'), so that leading
-	  bracket doesn't close the bracket expression.  Report from

-examples/loadables/Makefile.in
-	- rm: add rules to build rm as one of the `other' targets
+trap.c
+	- trap_handler: if we get a signal for which we have set a trap, but

-builtins/declare.def
-	- declare_internal: new (undocumented so far) option: -G. Means to
-	  act on global variables (create, modify) if no local variable is

-	- declare_find_variable: new declare-specific wrapper functon for

-subst.c
-	- shell_expand_word_list: before calling make_internal_declare, add

-parse.y
-	- clear_string_list_expander: take a pointer to an alias that's about

-alias.c
-	- free_alias_data: if an alias being freed is currently being expanded,
-	  call clear_string_list_expander to remove references to it from the

+arrayfunc.c
+	- assign_array_element: sanity check: make sure that the subscript

-bashline.c
-	- edit_and_execute_command,bash_execute_unix_command: restore the bash
-	  signal handlers before running parse_and_execute() so bash will catch
-	  and handle signals, instead of letting readline catch them without
-	  any opportunity to run _rl_handle_signal(). Fixes bug reported by
-	  Stan Marsh <gazelle@xmission.com>
+lib/readline/nls.c
+	- _rl_current_locale: private variable, stores the value of the
+	  LC_CTYPE locale category, as determined by _rl_init_locale; set
+	  to allocated memory in _rl_init_locale()
+	- _rl_set_localevars: new function, code from _rl_init_eightbit that
+	  checks the current locale (passed as an argument) and sets the
+	  various locale-aware variables based on it. It accepts a second
+	  argument: FORCE. If non-zero, it means to restore the default "C"
+	  locale values if the locale is "C" or "POSIX", now that this
+	  function can be called multiple times
+	- _rl_init_eightbit: now just calls _rl_init_locale and
+	  _rl_set_localevars
+	- _rl_reset_locale: new function, checks whether our the locale has
+	  changed since we last called _rl_init_locale to set our internal
+	  idea of its value. If it has changed, call _rl_set_localevars with
+	  the new locale and a FORCE argument of 1 to change the
+	  locale-dependent variables.

-	  nuance; we're just interested in whether or not there are any

-	- parameter_brace_expand: if we are expanding something like ${foo@a},
-	  pass PF_ALLINDS to parameter_brace_expand_word and
-	  parameter_brace_expand_indir so we don't get tripped up on `nounset'
-	  if foo has an assigned subscript other than 0/"0". Inspired by a

-	  entries, and HN_FIRST, which means we are parsing the first in a
-	  first,last range of history entries
-	- fc_gethnum: if we have a number >= 0, and it's out of range, return
-	  different values (0 or last history) depending on whether we are
-	  parsing the first or last in a range argument. Based on a report from
-	  Martijn Dekker <martijn@inlv.org>
+parse.y
+	- parse_comsub: don't clear the pushed string list; we might need it to

+builtins/exec.def

+	- get_var_and_type: now takes an array_eltstate_t * argument in place

+	  filename_bstab is set not to include the expansion char (and any

+	  sh_backslash_quote uses filename_bstab. Fixes the longstanding issue
+	  of quoting a `$', for instance, if the rest of the filename contains
+	  any characters that need quoting in filenames. This assumes that the
+	  filename is unquoted (*QCP == 0) so the word will be expanded and is

+This is a terse description of the new features added to bash-5.2 since
+the release of bash-5.1.  As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. The bash malloc returns memory that is aligned on 16-byte boundaries.
+
+b. There is a new internal timer framework used for read builtin timeouts.
+
+c. Rewrote the command substitution parsing code to call the parser recursively
+   and rebuild the command string from the parsed command. This allows better
+   syntax checking and catches errors much earlier. Along with this, if
+   command substitution parsing completes with here-documents remaining to be
+   read, the shell prints a warning message and reads the here-document bodies
+   from the current input stream.
+
+d. The `ulimit' builtin now treats an operand remaining after all of the options
+   and arguments are parsed as an argument to the last command specified by
+   an option. This is for POSIX compatibility.
+
+e. Here-document parsing now handles $'...' and $"..." quoting when reading the
+   here-document body.
+
+f. The `shell-expand-line' and `history-and-alias-expand-line' bindable readline
+   commands now understand $'...' and $"..." quoting.
+
+g. There is a new `spell-correct-word' bindable readline command to perform
+   spelling correction on the current word.
+
+h. The `unset' builtin now attempts to treat arguments as array subscripts
+   without parsing or expanding the subscript, even when `assoc_expand_once'
+   is not set.
+
+i. There is a default value for $BASH_LOADABLES_PATH in config-top.h.
+
+j. Associative array assignment and certain instances of referencing (e.g.,
+   `test -v' now allow `@' and `*' to be used as keys.
+
+k. Bash attempts to expand indexed array subscripts only once when executing
+   shell constructs and word expansions.
+
+l. The `unset' builtin allows a subscript of `@' or `*' to unset a key with
+   that value for associative arrays instead of unsetting the entire array
+   (which you can still do with `unset arrayname'). For indexed arrays, it
+   removes all elements of the array without unsetting it (like `A=()').
+
+m. Additional builtins (printf/test/read/wait) do a better job of not
+   parsing array subscripts if array_expand_once is set.
+
+n. New READLINE_ARGUMENT variable set to numeric argument for readline commands
+   defined using `bind -x'.
+
+o. The new `varredir_close' shell option causes bash to automatically close
+   file descriptors opened with {var}<fn and other styles of varassign
+   redirection unless they're arguments to the `exec' builtin.
+
+p. The `$0' special parameter is now set to the name of the script when running
+   any (non-interactive) startup files such as $BASH_ENV.
+
+q. The `enable' builtin tries to load a loadable builtin using the default
+   search path if `enable name' (without any options) attempts to enable a
+   non-existent builtin.
+
+r. The `printf' builtin has a new format specifier: %Q. This acts like %q but
+   applies any specified precision to the original unquoted argument, then
+   quotes and outputs the result.
+
+s. The new `noexpand_translations' option controls whether or not the translated
+   output of $"..." is single-quoted.
+
+t. There is a new parameter transformation operator: @k. This is like @K, but
+   expands the result to separate words after word splitting.
+
+u. There is an alternate array implementation, selectable at `configure' time,
+   that optimizes access speed over memory use (use the new configure
+    --enable-alt-array-implementation option).
+
+v. If an [N]<&WORD- or [N]>&WORD- redirection has WORD expand to the empty
+   string, treat the redirection as [N]<&- or [N]>&- and close file descriptor
+   N (default 0).
+
+w. Invalid parameter transformation operators are now invalid word expansions,
+   and so cause fatal errors in non-interactive shells.
+
+x. New shell option: patsub_replacement. When enabled, a `&' in the replacement
+   string of the pattern substitution expansion is replaced by the portion of
+   the string that matched the pattern. Backslash will escape the `&' and
+   insert a literal `&'.
+
+y. `command -p' no longer looks in the hash table for the specified command.
+
+z. The new `--enable-translatable-strings' option to `configure' allows $"..."
+   support to be compiled in or out.
+
+aa. The new `globskipdots' shell option forces pathname expansion never to
+    return `.' or `..' unless explicitly matched. It is enabled by default.
+
+bb. Array references using `@' and `*' that are the value of nameref variables
+    (declare -n ref='v[@]' ; echo $ref) no longer cause the shell to exit if
+    set -u is enabled and the array (v) is unset.
+
+cc. There is a new bindable readline command name:
+    `vi-edit-and-execute-command'.
+
+dd. In posix mode, the `printf' builtin checks for the `L' length modifier and
+    uses long double for floating point conversion specifiers if it's present,
+    double otherwise.
+
+ee. The `globbing' completion code now takes the `globstar' option into account.
+
+ff. `suspend -f' now forces the shell to suspend even if job control is not
+   currently enabled.
+
+gg. Since there is no `declare -' equivalent of `local -', make sure to use
+    `local -' in the output of `local -p'.
+
+2. New Features in Readline
+
+a. There is now an HS_HISTORY_VERSION containing the version number of the
+   history library for applications to use.
+
+b. History expansion better understands multiple history expansions that may
+   contain strings that would ordinarily inhibit history expansion (e.g.,
+   `abc!$!$').
+
+c. There is a new framework for readline timeouts, including new public
+   functions to set timeouts and query how much time is remaining before a
+   timeout hits, and a hook function that can trigger when readline times
+   out. There is a new state value to indicate a timeout.
+
+d. Automatically bind termcap key sequences for page-up and page-down to
+   history-search-backward and history-search-forward, respectively.
+
+e. There is a new `fetch-history' bindable command that retrieves the history
+   entry corresponding to its numeric argument. Negative arguments count back
+   from the end of the history.
+
+f. `vi-undo' is now a bindable command.
+
+g. There is a new option: `enable-active-region'. This separates control of
+   the active region and bracketed-paste. It has the same default value as
+   bracketed-paste, and enabling bracketed paste enables the active region.
+   Users can now turn off the active region while leaving bracketed paste
+   enabled.
+
+h. rl_completer_word_break_characters is now `const char *' like
+   rl_basic_word_break_characters.
+
+i. Readline looks in $LS_COLORS for a custom filename extension
+   (*.readline-colored-completion-prefix) and uses that as the default color
+   for the common prefix displayed when `colored-completion-prefix' is set.
+
+j. Two new bindable string variables: active-region-start-color and
+   active-region-end-color. The first sets the color used to display the
+   active region; the second turns it off. If set, these are used in place
+   of terminal standout mode.
+
+k. New readline state (RL_STATE_EOF) and application-visible variable
+   (rl_eof_found) to allow applications to detect when readline reads EOF
+   before calling the deprep-terminal hook.
+
+l. There is a new configuration option: --with-shared-termcap-library, which
+   forces linking the shared readline library with the shared termcap (or
+   curses/ncurses/termlib) library so applications don't have to do it.
+
+m. Readline now checks for changes to locale settings (LC_ALL/LC_CTYPE/LANG)
+   each time it is called, and modifies the appropriate locale-specific display
+   and key binding variables when the locale changes.

 # declarations like `int a3[[(sizeof (unsigned char)) >= 0]];'.
 # This bug is HP SR number 8606223364.

+       had  been  terminated  with the && control operator, with a two-way pipe
        established between the executing shell and the coprocess.
 
-       The format for a coprocess is:
+       The syntax for a coprocess is:
 
               ccoopprroocc [_N_A_M_E] _c_o_m_m_a_n_d [_r_e_d_i_r_e_c_t_i_o_n_s]
 
-       This  creates a coprocess named _N_A_M_E.  If _N_A_M_E is not supplied, the de-
-       fault name is CCOOPPRROOCC.  _N_A_M_E must not be supplied if _c_o_m_m_a_n_d is a _s_i_m_p_l_e
-       _c_o_m_m_a_n_d  (see above); otherwise, it is interpreted as the first word of
-       the simple command.  When the coprocess is executed, the shell  creates
-       an  array  variable (see AArrrraayyss below) named _N_A_M_E in the context of the
-       executing shell.  The standard output of _c_o_m_m_a_n_d  is  connected  via  a
-       pipe  to  a  file  descriptor in the executing shell, and that file de-
-       scriptor is assigned to _N_A_M_E[0].  The standard input of _c_o_m_m_a_n_d is con-
-       nected via a pipe to a file descriptor in the executing shell, and that
-       file descriptor is assigned to _N_A_M_E[1].  This pipe is  established  be-
-       fore any redirections specified by the command (see RREEDDIIRREECCTTIIOONN below).
-       The file descriptors can be utilized as arguments to shell commands and
-       redirections  using standard word expansions.  Other than those created
-       to execute command and process substitutions, the file descriptors  are
-       not available in subshells.  The process ID of the shell spawned to ex-
-       ecute the coprocess is available as the value of the variable _N_A_M_E_PID.
-       The  wwaaiitt builtin command may be used to wait for the coprocess to ter-
-       minate.
+       This creates a coprocess named _N_A_M_E.  _c_o_m_m_a_n_d may be  either  a  simple
+       command  or  a  compound command (see above).  _N_A_M_E is a shell variable
+       name.  If _N_A_M_E is not supplied, the default name is CCOOPPRROOCC.
+
+       The recommended form to use for a coprocess is
+
+              ccoopprroocc _N_A_M_E { _c_o_m_m_a_n_d [_r_e_d_i_r_e_c_t_i_o_n_s]; }
+
+       This form is recommended because simple commands result in  the  copro-
+       cess  always being named CCOOPPRROOCC, and it is simpler to use and more com-
+       plete than the other compound commands.
+
+       If _c_o_m_m_a_n_d is a compound command, _N_A_M_E is optional. The word  following
+       ccoopprroocc  determines whether that word is interpreted as a variable name:
+       it is interpreted as _N_A_M_E if it is not a reserved word that  introduces
+       a  compound  command.   If _c_o_m_m_a_n_d is a simple command, _N_A_M_E is not al-
+       lowed; this is to avoid confusion between _N_A_M_E and the  first  word  of
+       the simple command.
+
+       When  the  coprocess  is  executed, the shell creates an array variable
+       (see AArrrraayyss below) named _N_A_M_E in the context of  the  executing  shell.

-       Variables local to the function may be declared with the llooccaall  builtin
-       command.  Ordinarily, variables and their values are shared between the
-       function and its caller.  If a variable is declared  llooccaall,  the  vari-
-       able's  visible  scope  is restricted to that function and its children
-       (including the functions it calls).  Local variables "shadow" variables
-       with  the same name declared at previous scopes.  For instance, a local
-       variable declared in a function hides a global  variable  of  the  same
-       name:  references  and assignments refer to the local variable, leaving
-       the global variable unmodified.  When the function returns, the  global
-       variable is once again visible.

-       The  shell  uses  _d_y_n_a_m_i_c  _s_c_o_p_i_n_g  to  control a variable's visibility
-       within functions.  With dynamic scoping, visible  variables  and  their
-       values  are a result of the sequence of function calls that caused exe-
-       cution to reach the current function.  The value of a variable  that  a
-       function  sees  depends on its value within its caller, if any, whether
-       that caller is the "global" scope or another shell function.   This  is

+
+       In the following description, the _c_u_r_r_e_n_t _s_c_o_p_e is a currently- execut-
+       ing function.  Previous scopes consist of that function's caller and so
+       on,  back  to  the "global" scope, where the shell is not executing any
+       shell function.  Consequently, a local variable at the current scope is
+       a variable declared using the llooccaall or ddeeccllaarree builtins in the function
+       that is currently executing.
+
+       Local variables "shadow" variables with the same name declared at  pre-
+       vious  scopes.   For  instance, a local variable declared in a function
+       hides a global variable of the same name:  references  and  assignments

        value that is restored when the function returns.
 
-       For example, if a variable _v_a_r is declared as local in function  _f_u_n_c_1,
-       and  _f_u_n_c_1  calls  another  function _f_u_n_c_2, references to _v_a_r made from

        within _f_u_n_c_2 will resolve to the local variable _v_a_r from _f_u_n_c_1, shadow-
        ing any global variable named _v_a_r.
 
        The uunnsseett builtin also acts using the same dynamic scope: if a variable
        is local to the current scope, uunnsseett will unset it; otherwise the unset
-       will  refer  to  the  variable  found in any calling scope as described
-       above.  If a variable at the current local scope is unset, it will  re-
-       main  so until it is reset in that scope or until the function returns.
-       Once the function returns, any instance of the variable at  a  previous
-       scope will become visible.  If the unset acts on a variable at a previ-

+Prefixing a double-quoted string with a dollar sign ('$'), such as

+shell variables, as explained below.  See the gettext documentation for

+translated, the dollar sign is ignored.  Since this is a form of double
+quoting, the string remains double-quoted by default, whether or not it
+is translated and replaced.  If the 'noexpand_translation' option is
+enabled using the 'shopt' builtin (*note The Shopt Builtin::),
+translated strings are single-quoted instead of double-quoted.
+
+   The rest of this section is a brief overview of how you use gettext
+to create translations for strings in a shell script named SCRIPTNAME.
+There are more details in the gettext documentation.
+
+
+File: bash.info,  Node: Creating Internationalized Scripts,  Up: Locale Translation
+
+Once you've marked the strings in your script that you want to translate
+using $"...", you create a gettext "template" file using the command
+
+     bash --dump-po-strings SCRIPTNAME > DOMAIN.pot
+
+The DOMAIN is your "message domain".  It's just an arbitrary string
+that's used to identify the files gettext needs, like a package or
+script name.  It needs to be unique among all the message domains on
+systems where you install the translations, so gettext knows which
+translations correspond to your script.  You'll use the template file to
+create translations for each target language.  The template file
+conventionally has the suffix '.pot'.
+
+   You copy this template file to a separate file for each target
+language you want to support (called "PO" files, which use the suffix
+'.po').  PO files use various naming conventions, but when you are
+working to translate a template file into a particular language, you
+first copy the template file to a file whose name is the language you
+want to target, with the '.po' suffix.  For instance, the Spanish
+translations of your strings would be in a file named 'es.po', and to
+get started using a message domain named "example," you would run
+
+     cp example.pot es.po
+
+Ultimately, PO files are often named DOMAIN.po and installed in
+directories that contain multiple translation files for a particular
+language.
+
+   Whichever naming convention you choose, you will need to translate
+the strings in the PO files into the appropriate languages.  This has to
+be done manually.
+
+   When you have the translations and PO files complete, you'll use the
+gettext tools to produce what are called "MO" files, which are compiled
+versions of the PO files the gettext tools use to look up translations
+efficiently.  MO files are also called "message catalog" files.  You use
+the 'msgfmt' program to do this.  For instance, if you had a file with
+Spanish translations, you could run
+
+     msgfmt -o es.mo es.po
+
+to produce the corresponding MO file.
+
+   Once you have the MO files, you decide where to install them and use
+the 'TEXTDOMAINDIR' shell variable to tell the gettext tools where they
+are.  Make sure to use the same message domain to name the MO files as
+you did for the PO files when you install them.
+
+   Your users will use the 'LANG' or 'LC_MESSAGES' shell variables to
+select the desired language.
+
+   You set the 'TEXTDOMAIN' variable to the script's message domain.  As
+above, you use the message domain to name your translation files.
+
+   You, or possibly your users, set the 'TEXTDOMAINDIR' variable to the
+name of a directory where the message catalog files are stored.  If you
+install the message files into the system's standard message catalog
+directory, you don't need to worry about this variable.
+
+   The directory where the message catalog files are stored varies
+between systems.  Some use the message catalog selected by the
+'LC_MESSAGES' shell variable.  Others create the name of the message
+catalog from the value of the 'TEXTDOMAIN' shell variable, possibly
+adding the '.mo' suffix.  If you use the 'TEXTDOMAIN' variable, you may
+need to set the 'TEXTDOMAINDIR' variable to the location of the message
+catalog files, as above.  It's common to use both variables in this
+fashion: '$TEXTDOMAINDIR'/'$LC_MESSAGES'/LC_MESSAGES/'$TEXTDOMAIN'.mo.
+
+   If you used that last convention, and you wanted to store the message
+catalog files with Spanish (es) and Esperanto (eo) translations into a
+local directory you use for custom translation files, you could run
+
+     TEXTDOMAIN=example
+     TEXTDOMAINDIR=/usr/local/share/locale
+
+     cp es.mo ${TEXTDOMAINDIR}/es/LC_MESSAGES/${TEXTDOMAIN}.mo
+     cp eo.mo ${TEXTDOMAINDIR}/eo/LC_MESSAGES/${TEXTDOMAIN}.mo
+
+   When all of this is done, and the message catalog files containing
+the compiled translations are installed in the correct location, your
+users will be able to see translated strings in any of the supported
+languages by setting the 'LANG' or 'LC_MESSAGES' environment variables
+before running your script.

+
+     You can quote any part of the pattern to force the quoted portion
+     to be matched literally instead of as a regular expression (see
+     above).  If the pattern is stored in a shell variable, quoting the
+     variable expansion forces the entire pattern to be matched
+     literally.
+
+     The pattern will match if it matches any part of the string.  If
+     you want to force the pattern to match the entire string, anchor
+     the pattern using the '^' and '$' regular expression operators.
 
      For example, the following will match a line (stored in the shell
-     variable LINE) if there is a sequence of characters anywhere in the
-     value consisting of any number, including zero, of characters in
-     the 'space' character class, zero or one instances of 'a', then a
-     'b':
+     variable 'line') if there is a sequence of characters anywhere in
+     the value consisting of any number, including zero, of characters
+     in the 'space' character class, immediately followed by zero or one
+     instances of 'a', then a 'b':
+
           [[ $line =~ [[:space:]]*(a)?b ]]
 
-     That means values like 'aab' and ' aaaaaab' will match, as will a
-     line containing a 'b' anywhere in its value.
-
-     Storing the regular expression in a shell variable is often a
-     useful way to avoid problems with quoting characters that are
-     special to the shell.  It is sometimes difficult to specify a
-     regular expression literally without using quotes, or to keep track
-     of the quoting used by regular expressions while paying attention
-     to the shell's quote removal.  Using a shell variable to store the
-     pattern decreases these problems.  For example, the following is
-     equivalent to the above:
+     That means values for 'line' like 'aab', ' aaaaaab', 'xaby', and '
+     ab' will all match, as will a line containing a 'b' anywhere in its
+     value.
+
+     If you want to match a character that's special to the regular
+     expression grammar ('^$|[]()\.*+?'), it has to be quoted to remove
+     its special meaning.  This means that in the pattern 'xxx.txt', the
+     '.' matches any character in the string (its usual regular
+     expression meaning), but in the pattern '"xxx.txt"', it can only
+     match a literal '.'.
+
+     Likewise, if you want to include a character in your pattern that
+     has a special meaning to the regular expression grammar, you must
+     make sure it's not quoted.  If you want to anchor a pattern at the
+     beginning or end of the string, for instance, you cannot quote the
+     '^' or '$' characters using any form of shell quoting.
+
+     If you want to match 'initial string' at the start of a line, the
+     following will work:
+          [[ $line =~ ^"initial string" ]]
+     but this will not:
+          [[ $line =~ "^initial string" ]]
+     because in the second example the '^' is quoted and doesn't have
+     its usual special meaning.
+
+     It is sometimes difficult to specify a regular expression properly
+     without using quotes, or to keep track of the quoting used by
+     regular expressions while paying attention to shell quoting and the
+     shell's quote removal.  Storing the regular expression in a shell
+     variable is often a useful way to avoid problems with quoting
+     characters that are special to the shell.  For example, the
+     following is equivalent to the pattern used above:
+
           pattern='[[:space:]]*(a)?b'
           [[ $line =~ $pattern ]]
 
-     If you want to match a character that's special to the regular
-     expression grammar, it has to be quoted to remove its special
-     meaning.  This means that in the pattern 'xxx.txt', the '.' matches
-     any character in the string (its usual regular expression meaning),
-     but in the pattern '"xxx.txt"' it can only match a literal '.'.
      Shell programmers should take special care with backslashes, since
-     backslashes are used both by the shell and regular expressions to
-     remove the special meaning from the following character.  The
-     following two sets of commands are _not_ equivalent:

+     that were originally not quoted can remove the special meaning of

-
-   (You may have to modify the pattern if you have the 'dotglob' option
-enabled.)
-
-   GNU Parallel can replace certain common idioms that operate on lines
-read from a file (in this case, filenames listed one per line):
-     	while IFS= read -r x; do
-     		do-something1 "$x" "config-$x"
-     		do-something2 < "$x"
-     	done < file | process-output

-                process-output
-
-   Parallel provides a built-in mechanism to remove filename extensions,
-which lends itself to batch file transformations or renaming:
-     ls *.gz | parallel -j+0 "zcat {} | bzip2 >{.}.bz2 && rm {}"
-This will recompress all files in the current directory with names
-ending in .gz using bzip2, running one job per CPU (-j+0) in parallel.
-(We use 'ls' for brevity here; using 'find' as above is more robust in

-take arguments from the command line; the above can also be written as
-

+
+     In the first form above, only the first match is replaced.  If
+     there are two slashes separating PARAMETER and PATTERN (the second

+     null, matches of PATTERN are deleted.  If STRING is null, matches
+     of PATTERN are deleted and the '/' following PATTERN may be
+     omitted.
+
+     If the 'patsub_replacement' shell option is enabled using 'shopt',
+     any unquoted instances of '&' in STRING are replaced with the
+     matching portion of PATTERN.  This is intended to duplicate a
+     common 'sed' idiom.
+
+     Quoting any part of STRING inhibits replacement in the expansion of
+     the quoted portion, including replacement strings stored in shell
+     variables.  Backslash will escape '&' in STRING; the backslash is
+     removed in order to permit a literal '&' in the replacement string.
+     Users should take care if STRING is double-quoted to avoid unwanted
+     interactions between the backslash and double-quoting, since
+     backslash has special meaning within double quotes.  Pattern
+     substitution performs the check for unquoted '&' after expanding
+     STRING, so users should ensure to properly quote any occurrences of
+     '&' they want to be taken literally in the replacement and ensure
+     any instances of '&' they want to be replaced are unquoted.
+
+     For instance,
+
+          var=abcdef
+          rep='& '
+          echo ${var/abc/& }
+          echo "${var/abc/& }"
+          echo ${var/abc/$rep}
+          echo "${var/abc/$rep}"
+
+     will display four lines of "abc def", while
+
+          var=abcdef
+          rep='& '
+          echo ${var/abc/\& }
+          echo "${var/abc/\& }"
+          echo ${var/abc/"& "}
+          echo ${var/abc/"$rep"}
+
+     will display four lines of "& def".  Like the pattern removal
+     operators, double quotes surrounding the replacement string quote
+     the expanded characters, while double quotes enclosing the entire
+     parameter substitution do not, since the expansion is performed in
+     a context that doesn't take any enclosing double quotes into
+     account.
+
+     Since backslash can escape '&', it can also escape a backslash in
+     the replacement string.  This means that '\\' will insert a literal
+     backslash into the replacement, so these two 'echo' commands
+
+          var=abcdef
+          rep='\\&xyz'
+          echo ${var/abc/\\&xyz}
+          echo ${var/abc/$rep}
+
+     will both output '\abcxyzdef'.
+
+     It should rarely be necessary to enclose only STRING in double
+     quotes.
+
+     If the 'nocasematch' shell option (see the description of 'shopt'
+     in *note The Shopt Builtin::) is enabled, the match is performed
+     without regard to the case of alphabetic characters.  If PARAMETER

+<span id="index-internationalized-scripts"></span>
+<span id="index-string-translations"></span>
+<p>Once you&rsquo;ve marked the strings in your script
+that you want to translate using $&quot;...&quot;,
+you create a gettext &quot;template&quot; file using the command
+</p>
+<div class="example">
+<pre class="example">bash --dump-po-strings <var>scriptname</var> &gt; <var>domain</var>.pot
+</pre></div>
+
+<p>The <var>domain</var> is your <em>message domain</em>.
+It&rsquo;s just an arbitrary string that&rsquo;s used to identify the files gettext
+needs, like a package or script name.
+It needs to be unique among all
+the message domains on systems where you install the translations, so
+gettext knows which translations correspond to your script.
+You&rsquo;ll use the template file to create translations for each target language.
+The template file conventionally has the suffix &lsquo;<samp>.pot</samp>&rsquo;.
+</p>
+<p>You copy this template file to a separate file for each target language
+you want to support (called &quot;PO&quot; files, which use the suffix &lsquo;<samp>.po</samp>&rsquo;).
+PO files use various naming conventions, but
+when you are working to translate a template file into a particular
+language, you first copy the template file to a file whose name is the
+language you want to target, with the &lsquo;<samp>.po</samp>&rsquo; suffix.
+For instance, the Spanish translations of your strings would be
+in a file named &lsquo;<samp>es.po</samp>&rsquo;, and to get started using a message
+domain named &quot;example,&quot; you would run
+</p>
+<div class="example">
+<pre class="example">cp example.pot es.po
+</pre></div>
+
+<p>Ultimately, PO files are often named <var>domain</var>.po and installed in
+directories that contain multiple translation files for a particular language.
+</p>
+<p>Whichever naming convention you choose, you will need to translate the
+strings in the PO files into the appropriate languages.
+This has to be done manually.
+</p>
+<p>When you have the translations and PO files complete, you&rsquo;ll use the
+gettext tools to produce what are called &quot;MO&quot; files, which are compiled
+versions of the PO files the gettext tools use to look up translations
+efficiently.
+MO files are also called &quot;message catalog&quot; files.
+You use the <code>msgfmt</code> program to do this.
+For instance, if you had a file with Spanish translations, you could run
+</p>
+<div class="example">
+<pre class="example">msgfmt -o es.mo es.po
+</pre></div>
+
+<p>to produce the corresponding MO file.
+</p>
+<p>Once you have the MO files, you decide where to install them and use the
+<code>TEXTDOMAINDIR</code> shell variable to tell the gettext tools where they are.
+Make sure to use the same message domain to name the MO files 
+as you did for the PO files when you install them.

-<p>Some systems use the message catalog selected by the <code>LC_MESSAGES</code>
-shell variable.  Others create the name of the message catalog from the
-value of the <code>TEXTDOMAIN</code> shell variable, possibly adding a
-suffix of &lsquo;<samp>.mo</samp>&rsquo;.  If you use the <code>TEXTDOMAIN</code> variable, you
-may need to set the <code>TEXTDOMAINDIR</code> variable to the location of
-the message catalog files.  Still others use both variables in this
-fashion:
-<code>TEXTDOMAINDIR</code>/<code>LC_MESSAGES</code>/LC_MESSAGES/<code>TEXTDOMAIN</code>.mo.
+<p>Your users will use the <code>LANG</code> or <code>LC_MESSAGES</code> shell variables to
+select the desired language.
+</p>
+<p>You set the <code>TEXTDOMAIN</code> variable to the script&rsquo;s message domain.
+As above, you use the message domain to name your translation files.
+</p>
+<p>You, or possibly your users, set the <code>TEXTDOMAINDIR</code> variable to the
+name of a directory where the message catalog files are stored.
+If you install the message files into the system&rsquo;s standard message catalog
+directory, you don&rsquo;t need to worry about this variable.
+</p>
+<p>The directory where the message catalog files are stored varies between
+systems.
+Some use the message catalog selected by the <code>LC_MESSAGES</code>
+shell variable.
+Others create the name of the message catalog from the value of the
+<code>TEXTDOMAIN</code> shell variable, possibly adding the &lsquo;<samp>.mo</samp>&rsquo; suffix.
+If you use the <code>TEXTDOMAIN</code> variable, you may need to set the
+<code>TEXTDOMAINDIR</code> variable to the location of the message catalog files,
+as above.
+It&rsquo;s common to use both variables in this fashion:
+<code>$TEXTDOMAINDIR</code>/<code>$LC_MESSAGES</code>/LC_MESSAGES/<code>$TEXTDOMAIN</code>.mo.
+</p>
+<p>If you used that last convention, and you wanted to store the message
+catalog files with Spanish (es) and Esperanto (eo) translations into a
+local directory you use for custom translation files, you could run
+</p>
+<div class="example">
+<pre class="example">TEXTDOMAIN=example
+TEXTDOMAINDIR=/usr/local/share/locale
+
+cp es.mo ${TEXTDOMAINDIR}/es/LC_MESSAGES/${TEXTDOMAIN}.mo
+cp eo.mo ${TEXTDOMAINDIR}/eo/LC_MESSAGES/${TEXTDOMAIN}.mo
+</pre></div>
+
+<p>When all of this is done, and the message catalog files containing the
+compiled translations are installed in the correct location,
+your users will be able to see translated strings
+in any of the supported languages by setting the <code>LANG</code> or
+<code>LC_MESSAGES</code> environment variables before running your script.

 commands from its input sources to several different instances of Bash.
 </p>
-<p>For a complete description, refer to the GNU Parallel documentation.  A few
-examples should provide a brief introduction to its use.
-</p>
-<p>For example, it is easy to replace <code>xargs</code> to gzip all html files in the
-current directory and its subdirectories:
-</p><div class="example">
-<pre class="example">find . -type f -name '*.html' -print | parallel gzip
-</pre></div>
-<p>If you need to protect special characters such as newlines in file names,
-use find&rsquo;s <samp>-print0</samp> option and parallel&rsquo;s <samp>-0</samp> option.
-</p>
-<p>You can use Parallel to move files from the current directory when the
-number of files is too large to process with one <code>mv</code> invocation:
-</p><div class="example">
-<pre class="example">printf '%s\n' * | parallel mv {} destdir
-</pre></div>
-
-<p>As you can see, the {} is replaced with each line read from standard input.
-While using <code>ls</code> will work in most instances, it is not sufficient to
-deal with all filenames. <code>printf</code> is a shell builtin, and therefore is
-not subject to the kernel&rsquo;s limit on the number of arguments to a program,
-so you can use &lsquo;<samp>*</samp>&rsquo; (but see below about the <code>dotglob</code> shell option).
-If you need to accommodate special characters in filenames, you can use
-</p>
-<div class="example">
-<pre class="example">printf '%s\0' * | parallel -0 mv {} destdir
-</pre></div>
-
-<p>as alluded to above.
-</p>
-<p>This will run as many <code>mv</code> commands as there are files in the current
-directory.
-You can emulate a parallel <code>xargs</code> by adding the <samp>-X</samp> option:
-</p><div class="example">
-<pre class="example">printf '%s\0' * | parallel -0 -X mv {} destdir
-</pre></div>
-
-<p>(You may have to modify the pattern if you have the <code>dotglob</code> option
-enabled.)
-</p>
-<p>GNU Parallel can replace certain common idioms that operate on lines read
-from a file (in this case, filenames listed one per line):
-</p><div class="example">
-<pre class="example">	while IFS= read -r x; do
-		do-something1 &quot;$x&quot; &quot;config-$x&quot;
-		do-something2 &lt; &quot;$x&quot;
-	done &lt; file | process-output
-</pre></div>
-
-<p>with a more compact syntax reminiscent of lambdas:
-</p><div class="example">
-<pre class="example">cat list | parallel &quot;do-something1 {} config-{} ; do-something2 &lt; {}&quot; |
-           process-output
-</pre></div>
-
-<p>Parallel provides a built-in mechanism to remove filename extensions, which
-lends itself to batch file transformations or renaming:
-</p><div class="example">
-<pre class="example">ls *.gz | parallel -j+0 &quot;zcat {} | bzip2 &gt;{.}.bz2 &amp;&amp; rm {}&quot;
-</pre></div>
-<p>This will recompress all files in the current directory with names ending
-in .gz using bzip2, running one job per CPU (-j+0) in parallel.
-(We use <code>ls</code> for brevity here; using <code>find</code> as above is more
-robust in the face of filenames containing unexpected characters.)
-Parallel can take arguments from the command line; the above can also be
-written as
-</p>
-<div class="example">
-<pre class="example">parallel &quot;zcat {} | bzip2 &gt;{.}.bz2 &amp;&amp; rm {}&quot; ::: *.gz
-</pre></div>
-
-<p>If a command generates output, you may want to preserve the input order in
-the output.  For instance, the following command
-</p><div class="example">
-<pre class="example">{
-    echo foss.org.my ;
-    echo debian.org ;
-    echo freenetproject.org ;
-} | parallel traceroute
-</pre></div>
-<p>will display as output the traceroute invocation that finishes first.
-Adding the <samp>-k</samp> option 
-</p><div class="example">
-<pre class="example">{
-    echo foss.org.my ;
-    echo debian.org ;
-    echo freenetproject.org ;
-} | parallel -k traceroute
-</pre></div>
-<p>will ensure that the output of <code>traceroute foss.org.my</code> is displayed first.
-</p>
-<p>Finally, Parallel can be used to run a sequence of shell commands in parallel,
-similar to &lsquo;<samp>cat file | bash</samp>&rsquo;.
-It is not uncommon to take a list of filenames, create a series of shell
-commands to operate on them, and feed that list of commands to a shell.
-Parallel can speed this up.  Assuming that <samp>file</samp> contains a list of
-shell commands, one per line,
-</p>
-<div class="example">
-<pre class="example">parallel -j 10 &lt; file
-</pre></div>

-<p>will evaluate the commands using the shell (since no explicit command is
-supplied as an argument), in blocks of ten shell jobs at a time.

+This is intended to duplicate a common <code>sed</code> idiom.
+</p>
+<p>Quoting any part of <var>string</var> inhibits replacement in the
+expansion of the quoted portion, including replacement strings stored
+in shell variables.
+Backslash will escape &lsquo;<samp>&amp;</samp>&rsquo; in <var>string</var>; the backslash is removed
+in order to permit a literal &lsquo;<samp>&amp;</samp>&rsquo; in the replacement string.
+Users should take care if <var>string</var> is double-quoted to avoid
+unwanted interactions between the backslash and double-quoting, since
+backslash has special meaning within double quotes.
+Pattern substitution performs the check for unquoted &lsquo;<samp>&amp;</samp>&rsquo; after
+expanding <var>string</var>,
+so users should ensure to properly quote any occurrences of &lsquo;<samp>&amp;</samp>&rsquo;
+they want to be taken literally in the replacement
+and ensure any instances of &lsquo;<samp>&amp;</samp>&rsquo; they want to be replaced are unquoted.
+</p>
+<p>For instance,
+</p>
+<div class="example">
+<pre class="example">var=abcdef
+rep='&amp; '
+echo ${var/abc/&amp; }
+echo &quot;${var/abc/&amp; }&quot;
+echo ${var/abc/$rep}
+echo &quot;${var/abc/$rep}&quot;
+</pre></div>
+
+<p>will display four lines of &quot;abc def&quot;, while

+<div class="example">
+<pre class="example">var=abcdef

+echo ${var/abc/\&amp; }
+echo &quot;${var/abc/\&amp; }&quot;
+echo ${var/abc/&quot;&amp; &quot;}
+echo ${var/abc/&quot;$rep&quot;}
+</pre></div>
+
+<p>will display four lines of &quot;&amp; def&quot;.
+Like the pattern removal operators, double quotes surrounding the
+replacement string quote the expanded characters, while double quotes
+enclosing the entire parameter substitution do not, since
+the expansion is performed in a
+context that doesn&rsquo;t take any enclosing double quotes into account.
+</p>
+<p>Since backslash can escape &lsquo;<samp>&amp;</samp>&rsquo;, it can also escape a backslash in
+the replacement string.
+This means that &lsquo;<samp>\\</samp>&rsquo; will insert a literal
+backslash into the replacement, so these two <code>echo</code> commands

+Prefixing a double-quoted string with a dollar sign ('$'), such as

+shell variables, as explained below.  See the gettext documentation for
+additional details not covered here.  If the current locale is 'C' or

+quoting, the string remains double-quoted by default, whether or not it
+is translated and replaced.  If the 'noexpand_translation' option is
+enabled using the 'shopt' builtin (*note The Shopt Builtin::),
+translated strings are single-quoted instead of double-quoted.
+
+   The rest of this section is a brief overview of how you use gettext
+to create translations for strings in a shell script named SCRIPTNAME.
+There are more details in the gettext documentation.
+
+
+File: bashref.info,  Node: Creating Internationalized Scripts,  Up: Locale Translation
+
+Once you've marked the strings in your script that you want to translate
+using $"...", you create a gettext "template" file using the command
+
+     bash --dump-po-strings SCRIPTNAME > DOMAIN.pot
+
+The DOMAIN is your "message domain".  It's just an arbitrary string
+that's used to identify the files gettext needs, like a package or
+script name.  It needs to be unique among all the message domains on
+systems where you install the translations, so gettext knows which
+translations correspond to your script.  You'll use the template file to
+create translations for each target language.  The template file
+conventionally has the suffix '.pot'.
+
+   You copy this template file to a separate file for each target
+language you want to support (called "PO" files, which use the suffix
+'.po').  PO files use various naming conventions, but when you are
+working to translate a template file into a particular language, you
+first copy the template file to a file whose name is the language you
+want to target, with the '.po' suffix.  For instance, the Spanish
+translations of your strings would be in a file named 'es.po', and to
+get started using a message domain named "example," you would run
+
+     cp example.pot es.po
+
+Ultimately, PO files are often named DOMAIN.po and installed in
+directories that contain multiple translation files for a particular
+language.
+
+   Whichever naming convention you choose, you will need to translate
+the strings in the PO files into the appropriate languages.  This has to
+be done manually.
+
+   When you have the translations and PO files complete, you'll use the
+gettext tools to produce what are called "MO" files, which are compiled
+versions of the PO files the gettext tools use to look up translations
+efficiently.  MO files are also called "message catalog" files.  You use
+the 'msgfmt' program to do this.  For instance, if you had a file with
+Spanish translations, you could run
+
+     msgfmt -o es.mo es.po
+
+to produce the corresponding MO file.
+
+   Once you have the MO files, you decide where to install them and use
+the 'TEXTDOMAINDIR' shell variable to tell the gettext tools where they
+are.  Make sure to use the same message domain to name the MO files as
+you did for the PO files when you install them.
+
+   Your users will use the 'LANG' or 'LC_MESSAGES' shell variables to
+select the desired language.
+
+   You set the 'TEXTDOMAIN' variable to the script's message domain.  As
+above, you use the message domain to name your translation files.
+
+   You, or possibly your users, set the 'TEXTDOMAINDIR' variable to the
+name of a directory where the message catalog files are stored.  If you
+install the message files into the system's standard message catalog
+directory, you don't need to worry about this variable.
+
+   The directory where the message catalog files are stored varies
+between systems.  Some use the message catalog selected by the
+'LC_MESSAGES' shell variable.  Others create the name of the message
+catalog from the value of the 'TEXTDOMAIN' shell variable, possibly
+adding the '.mo' suffix.  If you use the 'TEXTDOMAIN' variable, you may
+need to set the 'TEXTDOMAINDIR' variable to the location of the message
+catalog files, as above.  It's common to use both variables in this
+fashion: '$TEXTDOMAINDIR'/'$LC_MESSAGES'/LC_MESSAGES/'$TEXTDOMAIN'.mo.
+
+   If you used that last convention, and you wanted to store the message
+catalog files with Spanish (es) and Esperanto (eo) translations into a
+local directory you use for custom translation files, you could run
+
+     TEXTDOMAIN=example
+     TEXTDOMAINDIR=/usr/local/share/locale
+
+     cp es.mo ${TEXTDOMAINDIR}/es/LC_MESSAGES/${TEXTDOMAIN}.mo
+     cp eo.mo ${TEXTDOMAINDIR}/eo/LC_MESSAGES/${TEXTDOMAIN}.mo
+
+   When all of this is done, and the message catalog files containing
+the compiled translations are installed in the correct location, your
+users will be able to see translated strings in any of the supported
+languages by setting the 'LANG' or 'LC_MESSAGES' environment variables
+before running your script.

      For example, the following will match a line (stored in the shell

+
           [[ $line =~ [[:space:]]*(a)?b ]]
 
-     That means values like 'aab' and ' aaaaaab' will match, as will a
-     line containing a 'b' anywhere in its value.
-
-     Storing the regular expression in a shell variable is often a
-     useful way to avoid problems with quoting characters that are
-     special to the shell.  It is sometimes difficult to specify a
-     regular expression literally without using quotes, or to keep track
-     of the quoting used by regular expressions while paying attention
-     to the shell's quote removal.  Using a shell variable to store the
-     pattern decreases these problems.  For example, the following is
-     equivalent to the above:
+     That means values for 'line' like 'aab', ' aaaaaab', 'xaby', and '
+     ab' will all match, as will a line containing a 'b' anywhere in its
+     value.
+
+     If you want to match a character that's special to the regular
+     expression grammar ('^$|[]()\.*+?'), it has to be quoted to remove
+     its special meaning.  This means that in the pattern 'xxx.txt', the
+     '.' matches any character in the string (its usual regular
+     expression meaning), but in the pattern '"xxx.txt"', it can only
+     match a literal '.'.
+
+     Likewise, if you want to include a character in your pattern that
+     has a special meaning to the regular expression grammar, you must
+     make sure it's not quoted.  If you want to anchor a pattern at the
+     beginning or end of the string, for instance, you cannot quote the
+     '^' or '$' characters using any form of shell quoting.
+
+     If you want to match 'initial string' at the start of a line, the

+     but this will not:
+          [[ $line =~ "^initial string" ]]
+     because in the second example the '^' is quoted and doesn't have

+
+     It is sometimes difficult to specify a regular expression properly
+     without using quotes, or to keep track of the quoting used by
+     regular expressions while paying attention to shell quoting and the
+     shell's quote removal.  Storing the regular expression in a shell
+     variable is often a useful way to avoid problems with quoting
+     characters that are special to the shell.  For example, the
+     following is equivalent to the pattern used above:
+
           pattern='[[:space:]]*(a)?b'
           [[ $line =~ $pattern ]]
 
-     If you want to match a character that's special to the regular
-     expression grammar, it has to be quoted to remove its special
-     meaning.  This means that in the pattern 'xxx.txt', the '.' matches
-     any character in the string (its usual regular expression meaning),
-     but in the pattern '"xxx.txt"' it can only match a literal '.'.
      Shell programmers should take special care with backslashes, since

-     printf '%s\0' * | parallel -0 -X mv {} destdir
-
-   (You may have to modify the pattern if you have the 'dotglob' option
-enabled.)
-
-   GNU Parallel can replace certain common idioms that operate on lines
-read from a file (in this case, filenames listed one per line):
-     	while IFS= read -r x; do
-     		do-something1 "$x" "config-$x"
-     		do-something2 < "$x"
-     	done < file | process-output

-     cat list | parallel "do-something1 {} config-{} ; do-something2 < {}" |
-                process-output
-
-   Parallel provides a built-in mechanism to remove filename extensions,
-which lends itself to batch file transformations or renaming:
-     ls *.gz | parallel -j+0 "zcat {} | bzip2 >{.}.bz2 && rm {}"
-This will recompress all files in the current directory with names
-ending in .gz using bzip2, running one job per CPU (-j+0) in parallel.
-(We use 'ls' for brevity here; using 'find' as above is more robust in
-the face of filenames containing unexpected characters.)  Parallel can
-take arguments from the command line; the above can also be written as
-
-     parallel "zcat {} | bzip2 >{.}.bz2 && rm {}" ::: *.gz
-
-   If a command generates output, you may want to preserve the input

-         echo foss.org.my ;
-         echo debian.org ;
-         echo freenetproject.org ;

-         echo freenetproject.org ;
-     } | parallel -k traceroute
-will ensure that the output of 'traceroute foss.org.my' is displayed
-first.
-
-   Finally, Parallel can be used to run a sequence of shell commands in
-parallel, similar to 'cat file | bash'.  It is not uncommon to take a
-list of filenames, create a series of shell commands to operate on them,

+     expansion, parameter and variable expansion, arithmetic expansion,
+     command and process substitution, and quote removal.  The match is
+     performed according to the rules described below (*note Pattern
+     Matching::).
+
+     In the first form above, only the first match is replaced.  If
+     there are two slashes separating PARAMETER and PATTERN (the second
+     form above), all matches of PATTERN are replaced with STRING.  If
+     PATTERN is preceded by '#' (the third form above), it must match at

+     preceded by '%' (the fourth form above), it must match at the end
+     of the expanded value of PARAMETER.  If the expansion of STRING is
+     null, matches of PATTERN are deleted.  If STRING is null, matches
+     of PATTERN are deleted and the '/' following PATTERN may be
+     omitted.
+
+     If the 'patsub_replacement' shell option is enabled using 'shopt',
+     any unquoted instances of '&' in STRING are replaced with the
+     matching portion of PATTERN.  This is intended to duplicate a
+     common 'sed' idiom.
+
+     Quoting any part of STRING inhibits replacement in the expansion of
+     the quoted portion, including replacement strings stored in shell
+     variables.  Backslash will escape '&' in STRING; the backslash is
+     removed in order to permit a literal '&' in the replacement string.
+     Users should take care if STRING is double-quoted to avoid unwanted
+     interactions between the backslash and double-quoting, since
+     backslash has special meaning within double quotes.  Pattern
+     substitution performs the check for unquoted '&' after expanding
+     STRING, so users should ensure to properly quote any occurrences of
+     '&' they want to be taken literally in the replacement and ensure
+     any instances of '&' they want to be replaced are unquoted.
+
+     For instance,
+
+          var=abcdef
+          rep='& '
+          echo ${var/abc/& }
+          echo "${var/abc/& }"
+          echo ${var/abc/$rep}
+          echo "${var/abc/$rep}"
+
+     will display four lines of "abc def", while
+
+          var=abcdef
+          rep='& '
+          echo ${var/abc/\& }
+          echo "${var/abc/\& }"
+          echo ${var/abc/"& "}
+          echo ${var/abc/"$rep"}
+
+     will display four lines of "& def".  Like the pattern removal
+     operators, double quotes surrounding the replacement string quote
+     the expanded characters, while double quotes enclosing the entire
+     parameter substitution do not, since the expansion is performed in
+     a context that doesn't take any enclosing double quotes into
+     account.
+
+     Since backslash can escape '&', it can also escape a backslash in
+     the replacement string.  This means that '\\' will insert a literal
+     backslash into the replacement, so these two 'echo' commands
+
+          var=abcdef
+          rep='\\&xyz'
+          echo ${var/abc/\\&xyz}
+          echo ${var/abc/$rep}
+
+     will both output '\abcxyzdef'.
+
+     It should rarely be necessary to enclose only STRING in double
+     quotes.
+
+     If the 'nocasematch' shell option (see the description of 'shopt'
+     in *note The Shopt Builtin::) is enabled, the match is performed
+     without regard to the case of alphabetic characters.  If PARAMETER

+send to that command.  This happens because the shell and the command
+are in the same process group as the terminal, and '^C' sends 'SIGINT'
+to all processes in that process group.  See *note Job Control::, for a
+more in-depth discussion of process groups.
+
+   When Bash is running without job control enabled and receives
+'SIGINT' while waiting for a foreground command, it waits until that
+foreground command terminates and then decides what to do about the
+'SIGINT':
+
+  1. If the command terminates due to the 'SIGINT', Bash concludes that
+     the user meant to end the entire script, and acts on the 'SIGINT'
+     (e.g., by running a 'SIGINT' trap or exiting itself);
+
+  2. If the pipeline does not terminate due to 'SIGINT', the program
+     handled the 'SIGINT' itself and did not treat it as a fatal signal.
+     In that case, Bash does not treat 'SIGINT' as a fatal signal,
+     either, instead assuming that the 'SIGINT' was used as part of the
+     program's normal operation (e.g., 'emacs' uses it to abort editing
+     commands) or deliberately discarded.  However, Bash will run any
+     trap set on 'SIGINT', as it does with any other trapped signal it
+     receives while it is waiting for the foreground command to
+     complete, for compatibility.

+
+The rest of this section is a brief overview of how you use gettext to
+create translations for strings in a shell script named @var{scriptname}.
+There are more details in the gettext documentation.
+
+@node Creating Internationalized Scripts
+@cindex internationalized scripts
+@cindex string translations
+Once you've marked the strings in your script
+that you want to translate using $"...",
+you create a gettext "template" file using the command
+
+@example
+bash --dump-po-strings @var{scriptname} > @var{domain}.pot
+@end example
+
+@noindent
+The @var{domain} is your @dfn{message domain}.
+It's just an arbitrary string that's used to identify the files gettext
+needs, like a package or script name.
+It needs to be unique among all
+the message domains on systems where you install the translations, so
+gettext knows which translations correspond to your script.
+You'll use the template file to create translations for each target language.
+The template file conventionally has the suffix @samp{.pot}.
+
+You copy this template file to a separate file for each target language
+you want to support (called "PO" files, which use the suffix @samp{.po}).
+PO files use various naming conventions, but
+when you are working to translate a template file into a particular
+language, you first copy the template file to a file whose name is the
+language you want to target, with the @samp{.po} suffix.
+For instance, the Spanish translations of your strings would be
+in a file named @samp{es.po}, and to get started using a message
+domain named "example," you would run
+
+@example
+cp example.pot es.po
+@end example
+
+@noindent
+Ultimately, PO files are often named @var{domain}.po and installed in
+directories that contain multiple translation files for a particular language.
+
+Whichever naming convention you choose, you will need to translate the
+strings in the PO files into the appropriate languages.
+This has to be done manually.
+
+When you have the translations and PO files complete, you'll use the
+gettext tools to produce what are called "MO" files, which are compiled
+versions of the PO files the gettext tools use to look up translations
+efficiently.
+MO files are also called "message catalog" files.
+You use the @command{msgfmt} program to do this.
+For instance, if you had a file with Spanish translations, you could run
 
+@example
+msgfmt -o es.mo es.po
+@end example
+
+@noindent
+to produce the corresponding MO file.
+
+Once you have the MO files, you decide where to install them and use the
+@code{TEXTDOMAINDIR} shell variable to tell the gettext tools where they are.
+Make sure to use the same message domain to name the MO files 
+as you did for the PO files when you install them.

+
+You set the @env{TEXTDOMAIN} variable to the script's message domain.
+As above, you use the message domain to name your translation files.
+
+You, or possibly your users, set the @env{TEXTDOMAINDIR} variable to the
+name of a directory where the message catalog files are stored.
+If you install the message files into the system's standard message catalog
+directory, you don't need to worry about this variable.
+
+The directory where the message catalog files are stored varies between
+systems.
+Some use the message catalog selected by the @env{LC_MESSAGES}
+shell variable.
+Others create the name of the message catalog from the value of the
+@env{TEXTDOMAIN} shell variable, possibly adding the @samp{.mo} suffix.
+If you use the @env{TEXTDOMAIN} variable, you may need to set the
+@env{TEXTDOMAINDIR} variable to the location of the message catalog files,
+as above.
+It's common to use both variables in this fashion:
+@env{$TEXTDOMAINDIR}/@env{$LC_MESSAGES}/LC_MESSAGES/@env{$TEXTDOMAIN}.mo.
+
+If you used that last convention, and you wanted to store the message
+catalog files with Spanish (es) and Esperanto (eo) translations into a
+local directory you use for custom translation files, you could run
+
+@example
+TEXTDOMAIN=example
+TEXTDOMAINDIR=/usr/local/share/locale
+
+cp es.mo $@{TEXTDOMAINDIR@}/es/LC_MESSAGES/$@{TEXTDOMAIN@}.mo
+cp eo.mo $@{TEXTDOMAINDIR@}/eo/LC_MESSAGES/$@{TEXTDOMAIN@}.mo
+@end example
+
+When all of this is done, and the message catalog files containing the
+compiled translations are installed in the correct location,
+your users will be able to see translated strings
+in any of the supported languages by setting the @env{LANG} or
+@env{LC_MESSAGES} environment variables before running your script.

-@example
-printf '%s\n' * | parallel mv @{@} destdir

-
-As you can see, the @{@} is replaced with each line read from standard input.
-While using @code{ls} will work in most instances, it is not sufficient to

+================================================================================
+
+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<https://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<https://www.gnu.org/licenses/why-not-lgpl.html>.

+# Shellmath
+Introducing decimal arithmetic libraries for the Bash shell, because
+they said it couldn't be done... and because:
+
+.
+
+![image info](./image.png)
+
+## Quick-start guide
+Download this project and source the file `shellmath.sh` into your shell script,
+then fire away at the shellmath API!
+
+The ___basic___ API looks like this:
+```
+    _shellmath_add        arg1   arg2  [...]  argN
+    _shellmath_subtract   arg1   arg2               # means arg1 - arg2
+    _shellmath_multiply   arg1   arg2  [...]  argN
+    _shellmath_divide     arg1   arg2               # means arg1 / arg2
+```
+
+The ___extended___ API introduces one more function:
+```
+    _shellmath_getReturnValue   arg
+```
+
+This function optimizes away the need for ___$(___ subshelling ___)___ in order to capture `shellmath`'s output.
+To use this feature, just be sure to set `__shellmath_isOptimized=1` at the top
+of your script. (You can find an example in `faster_e_demo.sh`.)
+
+Operands to the _shellmath_ functions can be integers or decimal
+numbers presented in either standard or scientific notation:
+```
+    _shellmath_add   1.009   4.223e-2
+    _shellmath_getReturnValue   sum
+    echo "The sum is $sum"
+```
+Addition and multiplication are of arbitrary arity; try this on for size:
+```
+    _shellmath_multiply  1  2  3  4  5  6
+    _shellmath_getReturnValue   sixFactorial
+    echo "6 factorial is $sixFactorial"
+```
+Subtraction and division, OTOH, are exclusively binary operations. 
+
+## The demos
+For a gentle introduction to `shellmath` run the demo `slower_e_demo.sh` 
+with a small whole-number argument, say 15:
+```
+$ slower_e_demo.sh 15
+e = 2.7182818284589936
+```
+
+This script uses a few `shellmath` API calls to calculate *e*, the mathematical
+constant also known as [Euler's number](https://oeis.org/A001113). The argument 
+*15* tells the script to evaluate the *15th-degree* Maclaurin polynomial for *e*.
+(That's the Taylor polynomial centered at 0.) Take a look inside the script to
+see how it uses the `shellmath` APIs.
+
+There is another demo script very much like this one but *different*, and the
+sensitive user can *feel* the difference. Try the following, but don't blink 
+or you'll miss it ;)
+```
+$ faster_e_demo.sh 15
+e = 2.7182818284589936
+```
+
+Did you feel the difference? Try the `-t` option with both scripts; this will produce
+timing statistics. Here are my results
+when running from my minGW64 command prompt on Windows 10 with an Intel i3 Core CPU:
+```
+$ for n in {1..5}; do faster_e_demo.sh -t 15 2>&1; done | awk '/^real/ {print $2}'
+0m0.055s
+0m0.051s
+0m0.056s
+0m0.054s
+0m0.054s
+
+$ for n in {1..5}; do slower_e_demo.sh -t 15 2>&1; done | awk '/^real/ {print $2}'
+0m0.498s
+0m0.594s
+0m0.536s
+0m0.511s
+0m0.580s
+```
+
+(When sizing up these timings, do keep in mind that ___we are timing the
+calculation of e from its Maclaurin polynomial. Every invocation of either
+script is exercising the shellmath arithmetic subroutines 31 times.___)

+## Runtime efficiency competitive with awk and bc
+The file `timingData.txt` captures the results of some timing experiments that compare 
+`shellmath` against the GNU versions of the calculators `awk` and `bc`. The experiments
+exercised each of the arithmetic operations and captured the results in a shell variable.
+The result summary below shows that `shellmath` is competitive with `awk` and runs faster
+than `bc` in these experiments. (One commenter noted that the differences in execution speed
+can be partially explained by the fact that `shellmath` and `awk` use finite precision 
+whereas `bc` uses arbitrary precision. Another factor in these measurements is the need to 
+subshell 'awk' and 'bc' to capture their results, whereas 'shellmath' writes directly to
+the shell's global memory.)
+
+Here are the run times of `shellmath` as a percentage of the `awk` and `bc` equivalents:
+```
+                    versus awk    versus bc
+   Addition:          82.2%         40.6%
+   Subtraction:       95.9%         50.5%
+   Multiplication:   135.9%         73.3%
+   Division:          80.3%         43.2%
+```
+
+Astute observers will note the experiments provide approximations to the sum, difference, 
+product, and quotient of *pi* and *e*. Unfortunately I did not gain insight as to which 
+of these values, if any, are
+[transcendental](https://en.wikipedia.org/wiki/Transcendental_number#Possible_transcendental_numbers).
+
+You can find a deeper discussion of shellmath's runtime efficiency
+[here](https://github.com/clarity20/shellmath/wiki/Shellmath-and-runtime-efficiency).
+
+## Background
+The Bash shell does not have built-in operators for decimal arithmetic, making it
+something of an oddity among well-known, widely-used programming languages. For the most part,
+practitioners in need of powerful computational building blocks have naturally opted
+for *other* languages and tools. Their widespread availability has diverted attention
+from the possibility of *implementing* decimal arithmetic in Bash and it's easy to assume
+that this ***cannot*** be done:
+
++ From the indispensable _Bash FAQ_ (on _Greg's Wiki_): [How can I calculate with floating point numbers?](http://mywiki.wooledge.org/BashFAQ/022)  
+  *"For most operations... an external program must be used."*
++ From Mendel Cooper's wonderful and encyclopedic _Advanced Bash Scripting Guide_:  
+  [Bash does not understand floating point arithmetic. Use bc instead.](https://tldp.org/LDP/abs/html/ops.html#NOFLOATINGPOINT)
++ From a community discussion on Stack Overflow, _How do I use floating point division in bash?_  
+  The user's [preferred answer](https://stackoverflow.com/questions/12722095/how-do-i-use-floating-point-division-in-bash#12722107)
+  is a good example of _prevailing thought_ on this subject.
+
+Meanwhile, 
+
++ Bash maintainer (BDFL?) Chet Ramey sounds a (brighter?) note in [The Bash Reference Guide, Section 6.5](https://tiswww.case.edu/php/chet/bash/bashref.html#Shell-Arithmetic)
+  by emphasizing what the built-in arithmetic operators ***can*** do.
+
+But finally, a glimmer of hope:
+
++ A [diamond-in-the-rough](http://stackoverflow.com/a/24431665/3776858) buried elsewhere
+  on Stack Overflow.  
+  This down-and-dirty milestone computes the decimal quotient of two integer arguments. At a casual
+  glance, it seems to have drawn inspiration from the [Euclidean algorithm](https://mathworld.wolfram.com/EuclideanAlgorithm.html)
+  for computing GCDs, an entirely different approach than `shellmath`'s.
+
+Please try `shellmath` on for size and draw your own conclusions!
+
+## How it works
+`shellmath` splits decimal numbers into their integer and fractional parts,
+performs the appropriate integer operations on the parts, and recombines the results.
+(In the spirit of Bash, numerical overflow is silently ignored.)
+
+Because if we can get carrying, borrowing, place value, and the distributive
+law right, then the sky's the limit! As they say--erm, as they ___said___ in Rome,
+
+        Ad astra per aspera.
+
+## And now...
+You can run your floating-point calculations directly in Bash!
+

 #
-# KNOWN DEFECTS (easy fixes, tedious work; sorted by priority):
-#  0. Translation coverage when upstream sends new strings.
+# 本翻译目�采用的格�约定，和其他注�事项：
 #
-#  1. Argument lists in `help` are translated, but the `help blah` text still
-#     refers to the original name like WORDS.
-#
-#     These long helps should be changed to follow their `help` synopsis.  Use
-#     <�数> to refer to `�数' in the one-line synopsis.
-#
-#  2. Passive voice.  When used inappropriately, they sound even worse in
-#     Chinese than in English.  In fact huge amounts of `被' is what you use to
-#     spot translated text.  (You don't always need `被' for passive voice
-#     either.)
-#
-#  3. Typography.
-#     a. Capitalization.  English convensions mangle command names in help text
-#        if it's the first word of the sentense (e.g. `Getopts blah blah...').
-#        Do yourself a favor and change the names back into lowercase.
-#     b. Quotes.  Chinese has no `typewriter quote' convension, and standard
-#        “curly quotes� should be used.
-#     c. Colons.  We don't use `: ` in Chinese; use `：`.  Sometimes `:` is seen
-#        w/o a space (worse).
-#     d. Other stuff like parentheses and whitespace.  Alignment can be quite
-#        important for Feeling Good(TM).
+# 1. 冒�：冒�左边最近的分��有中文字符时，使用中文冒�，�则使用英文冒�。
+# 2. 引�：永远使用 " "，除�被引用的字符是 " 或 '，此时�留原文（一般是 ` '）。
+# 3. 括�：括�内�有中文字符时，使用中文括�，�则使用英文括�。
+# 4. 命令帮助中，�行用法里的�替��语（如“�称�）在完整帮助中应写� <�称>，
+#    尖括�两边按照英文括�的原则加空格。
+# 5. 注�统一术语，�确定的术语先�索此文件看看。新术语强烈推�“术语在线�网站。
+# 6. �常查看上下文（�代�）对翻译的正确率很有帮助。
