sed
Example
If the variable _UNIX03=YES is set and a backslash followed by an ’n’
appear in set1 or set2, the two characters are handled as a single newline
character. If the variable _UNIX03 is unset or is not set to YES, the two
characters are handled as a single character ’n’.
If the delimiter is not ’n’, within set1 and set2, the delimiter itself can be
used as a literal character if it is preceded by a backslash. If a backslash
character is immediately followed by a backslash character in set1 or set2,
the two backslash characters are counted as a single literal backslash
character.
a,b{ Groups all commands until the next matching } subcommand, so that sed
runs the entire group only if the { subcommand is selected by its
address(es).
:label Designates a label, which can be the destination of a bor t subcommand.
# Treats the script line as a comment unless it is the first line in the script.
Including the first line in a script as #n is equivalent to specifying –n on the
command line. An empty script line is also treated as a comment.
a= Writes the decimal value of the current line number to the standard output.
This filter switches desserts in a menu:
