NAME

       ainsl - AppendIfNoSuchLine

SYNOPSIS

       ainsl [options] FILE LINE [PATTERN]

DESCRIPTION

       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: ( ) +

OPTIONS

       -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 matching.

       -v     Create verbose output.

EXAMPLES

       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.

NOTES

       This is a similar function to AppendIfNoSuchLine from cfengine(8).
