The exit code -argument is a GNU extension. -.TP -Q [\fIexit-code\fR] -Immediately quit the \*(sd script without processing -any more input. This is a GNU extension. -.TP -.RI r\ filename -Append text read from -.IR filename . -.TP -.RI R\ filename -Append a line read from -.IR filename . -Each invocation of the command reads a line from the file. -This is a GNU extension. -.SS -Commands which accept address ranges -.TP -{ -Begin a block of commands (end with a }). -.TP -.RI b\ label -Branch to -.IR label ; -if -.I label -is omitted, branch to end of script. -.TP -c \e -.TP -.I text -Replace the selected lines with -.IR text , -which has each embedded newline preceded by a backslash. -.TP -d -Delete pattern space. -Start next cycle. -.TP -D -If pattern space contains no newline, start a normal new cycle as if -the d command was issued. Otherwise, delete text in the pattern -space up to the first newline, and restart cycle with the resultant -pattern space, without reading a new line of input. -.TP -h H -Copy/append pattern space to hold space. -.TP -g G -Copy/append hold space to pattern space. -.TP -l -List out the current line in a ``visually unambiguous'' form. -.TP -.RI l\ width -List out the current line in a ``visually unambiguous'' form, -breaking it at -.I width -characters. This is a GNU extension. -.TP -n N -Read/append the next line of input into the pattern space. -.TP -p -Print the current pattern space. -.TP -P -Print up to the first embedded newline of the current pattern space. -.TP -.RI s/ regexp / replacement / -Attempt to match -.I regexp -against the pattern space. -If successful, replace that portion matched -with -.IR replacement . -The -.I replacement -may contain the special character -.B & -to refer to that portion of the pattern space which matched, -and the special escapes \e1 through \e9 to refer to the -corresponding matching sub-expressions in the -.IR regexp . -.TP -.RI t\ label -If a s/// has done a successful substitution since the -last input line was read and since the last t or T -command, then branch to -.IR label ; -if -.I label -is omitted, branch to end of script. -.TP -.RI T\ label -If no s/// has done a successful substitution since the -last input line was read and since the last t or T -command, then branch to -.IR label ; -if -.I label -is omitted, branch to end of script. This is a GNU -extension. -.TP -.RI w\ filename -Write the current pattern space to -.IR filename . -.TP -.RI W\ filename -Write the first line of the current pattern space to -.IR filename . -This is a GNU extension. -.TP -x -Exchange the contents of the hold and pattern spaces. -.TP -.RI y/ source / dest / -Transliterate the characters in the pattern space which appear in -.I source -to the corresponding character in -.IR dest . -.SH -Addresses -\*(Sd commands can be given with no addresses, in which -case the command will be executed for all input lines; -with one address, in which case the command will only be executed -for input lines which match that address; or with two -addresses, in which case the command will be executed -for all input lines which match the inclusive range of -lines starting from the first address and continuing to -the second address. -Three things to note about address ranges: -the syntax is -.IR addr1 , addr2 -(i.e., the addresses are separated by a comma); -the line which -.I addr1 -matched will always be accepted, -even if -.I addr2 -selects an earlier line; -and if -.I addr2 -is a -.IR regexp , -it will not be tested against the line that -.I addr1 -matched. -.PP -After the address (or address-range), -and before the command, a -.B ! -may be inserted, -which specifies that the command shall only be -executed if the address (or address-range) does -.B not -match. -.PP -The following address types are supported: -.TP -.I number -Match only the specified line -.IR number -(which increments cumulatively across files, unless the -.B -s -option is specified on the command line). -.TP -.IR first ~ step -Match every -.IR step 'th -line starting with line -.IR first . -For example, ``sed -n 1~2p'' will print all the odd-numbered lines in -the input stream, and the address 2~5 will match every fifth line, -starting with the second. -.I first -can be zero; in this case, \*(sd operates as if it were equal to -.IR step . -(This is an extension.) -.TP -$ -Match the last line. -.TP -.RI / regexp / -Match lines matching the regular expression -.IR regexp . -.TP -.BI \fR\e\fPc regexp c -Match lines matching the regular expression -.IR regexp . -The -.B c -may be any character. -.PP -GNU \*(sd also supports some special 2-address forms: -.TP -.RI 0, addr2 -Start out in "matched first address" state, until -.I addr2 -is found. -This is similar to -.RI 1, addr2 , -except that if -.I addr2 -matches the very first line of input the -.RI 0, addr2 -form will be at the end of its range, whereas the -.RI 1, addr2 -form will still be at the beginning of its range. -This works only when -.I addr2 -is a regular expression. -.TP -.IR addr1 ,+ N -Will match -.I addr1 -and the -.I N -lines following -.IR addr1 . -.TP -.IR addr1 ,~ N -Will match -.I addr1 -and the lines following -.I addr1 -until the next line whose input line number is a multiple of -.IR N . -.SH "REGULAR EXPRESSIONS" -POSIX.2 BREs -.I should -be supported, but they aren't completely because of performance -problems. -The -.B \en -sequence in a regular expression matches the newline character, -and similarly for -.BR \ea , -.BR \et , -and other sequences. -The \fI-E\fP option switches to using extended regular expressions instead; -the -E option has been supported for years by GNU sed, and is now -included in POSIX. -.SH BUGS -.PP -E-mail bug reports to -.BR bug-sed@gnu.org . -Also, please include the output of ``sed --version'' in the body -of your report if at all possible. -.SH AUTHOR -Written by Jay Fenlason, Tom Lord, Ken Pizzini, -and Paolo Bonzini. -GNU sed home page: <http://www.gnu.org/software/sed/>. -General help using GNU software: <http://www.gnu.org/gethelp/>. -E-mail bug reports to: <bug-sed@gnu.org>. -Be sure to include the word ``sed'' somewhere in the ``Subject:'' field. -.SH COPYRIGHT -Copyright \(co 2014 Free Software Foundation, Inc. -License GPLv3+: GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html>. -.br -This is free software: you are free to change and redistribute it. -There is NO WARRANTY, to the extent permitted by law. -.SH "SEE ALSO" -.BR awk (1), -.BR ed (1), -.BR grep (1), -.BR tr (1), -.BR perlre (1), -sed.info, -any of various books on \*(sd, -.na -the \*(sd FAQ (http://sed.sf.net/grabbag/tutorials/sedfaq.txt), -http://sed.sf.net/grabbag/. -.PP -The full documentation for -.B sed -is maintained as a Texinfo manual.
