[linux-help] Re: Regexp question

[Steven Saner <ssaner@xxxxxxxxxxxxxxx>]

Is this a perl regexp? If so you can use !~ to invert a regexp. So you
could do:

if ($var !~ m/foobar.*/)

That would be true only if $var does not match m/foobar.*/

If you are using a regexp with grep on the command line, you can do a
similar thing with the -v option.

grep -v 'foobar.*' file

That will return all lines in the file that do not match foobar.*

Is that what you are after?
