ainsl - AppendIfNoSuchLine
ainsl [options] FILE LINE [PATTERN]
Add LINE to the end of FILE if this file does not contain this line
already. If PATTERN is given, then the LINE is only appended if PATTERN
is not found in the file.
If PATTERN is not given, LINE is used instead for matching a line in
FILE. Then LINE may also contain the anchors '^' and '$' which are only
treated specialy at the beginning or end of the pattern and are used
for matching, not when adding the line. Additionaly, the following
characters are escaped in LINE: ( ) +
-a Autocreate file if it does not exist.
-D Create debugging output.
-h Show help, version and summary of options.
-n Print the actions, but do not execute them.
-Q Quote all metacharacters in pattern. Uses perl's \Q function.
-q Quote * and + metacharacters in pattern.
-s Convert white space in LINE or PATTERN to '\s+' regexp for
-v Create verbose output.
ainsl -v /etc/fstab '/dev/fd0 /floppy auto users,noauto 0 0'
Append the entry for the floppy device to /etc/fstab, if this line
isn't already inlcuded.
ainsl -s /etc/exports '/srv/www @linuxhosts(async,rw) backup(async,ro)'
Add exports entry without exactly matching spaces.
This is a similar function to AppendIfNoSuchLine from cfengine(8).
