               When the shell is not interactive, signals ignored upon entry to
               the shell cannot be trapped or reset.  Interactive shells permit
               trapping signals ignored on entry.  Trapped signals that are not
-              being  ignored  are reset to their original values in a subshell

+Control how the results of pathname expansion are sorted.
+The value of this variable specifies the sort criteria and sort order for

+If this variable is unset or set to the null string, pathname expansion
+uses the historial behavior of sorting by name.
+If set, a valid value begins with an optional <I>+</I>, which is ignored,

+<p><small>POSIX</small> is the name for a family of standards based on Unix.
+A number of Unix services, tools, and functions are part of the standard,
+ranging from the basic system calls and C library functions to common
+applications and tools to system administration and management.
+</p>
+<p>The <small>POSIX</small> Shell and Utilities standard was originally developed by
+IEEE Working Group 1003.2 (POSIX.2).
+The first edition of the 1003.2 standard was published in 1992.
+It was merged with the original IEEE 1003.1 Working Group and is
+currently maintained by the Austin Group (a joint working group of the
+IEEE, The Open Group and ISO/IEC SC22/WG15).
+Today the Shell and Utilities are a volume within the set of documents that
+make up IEEE Std 1003.1-2017, and thus the former POSIX.2 (from 1992)
+is now part of the current unified <small>POSIX</small> standard.
+</p>
+<p>The Shell and Utilities volume concentrates on the command
+interpreter interface and utility programs commonly executed from
+the command line or by other programs.
+The standard is freely available on the web at
+<a href="https://pubs.opengroup.org/onlinepubs/9699919799/utilities/contents.html">https://pubs.opengroup.org/onlinepubs/9699919799/utilities/contents.html</a>.
+</p>
+<p>Bash is concerned with the aspects of the shell&rsquo;s behavior defined
+by the <small>POSIX</small> Shell and Utilities volume.  The shell command
+language has of course been standardized, including the basic flow
+control and program execution constructs, I/O redirection and
+pipelines, argument handling, variable expansion, and quoting.
+</p>
+<p>The <i>special</i> builtins, which must be implemented as part of the
+shell to provide the desired functionality, are specified as
+being part of the shell; examples of these are <code>eval</code> and
+<code>export</code>.
+Other utilities appear in the sections of POSIX not
+devoted to the shell which are commonly (and in some cases must
+be) implemented as builtin commands, such as
+<code>read</code> and <code>test</code>.
+POSIX also specifies aspects of the shell&rsquo;s interactive
+behavior, including job control and command
+line editing.
+Only vi-style line editing commands have been
+standardized; emacs editing commands were left out due to
+objections.

+              ggeettooppttss  is used by shell procedures to parse positional parame-
+              ters.  _o_p_t_s_t_r_i_n_g contains the option  characters  to  be  recog-
+              nized;  if a character is followed by a colon, the option is ex-
               pected to have an argument, which should be separated from it by
-              white space.  The colon and question mark characters may not  be
-              used  as  option  characters.   Each time it is invoked, ggeettooppttss
-              places the next option in the shell variable _n_a_m_e,  initializing

               _n_a_m_e if it does not exist, and the index of the next argument to
               be processed into the variable OOPPTTIINNDD.  OOPPTTIINNDD is initialized to
               1 each time the shell or a shell script is invoked.  When an op-
               tion requires an argument, ggeettooppttss places that argument into the
               variable OOPPTTAARRGG.  The shell does not reset OOPPTTIINNDD automatically;
-              it must be manually reset  between  multiple  calls  to  ggeettooppttss

               to be used.
 
               When the end of options is encountered, ggeettooppttss exits with a re-
               turn value greater than zero.  OOPPTTIINNDD is set to the index of the
               first non-option argument, and _n_a_m_e is set to ?.
 
-              ggeettooppttss normally parses the positional parameters, but  if  more
