grep Matching anything except pattern

Paul Sperry — Tue, 20 Nov 2007 10:16:35 GMT

Hi all,

I have a bunch of email lists that I need to find out which one have external addresses.
I have used grep to find file pattern matches but never to find ones that don't match. I did a man grep but didn't see any ideas. How can I use find/grep to to find all files that contain addresses other than @mydomain.com

TIA
Paul

Explore grep's '-v' option.

When you did a "man grep", you didn't look hard enough. Use the -v option which lists all lines except those matching the pattern.

Hi Paul:

The '-v' switch of 'grep' negates a match. That is, 'grep -v' finds everything that does NOT match:

Compare :

# grep local /etc/hosts

...with:

# grep -v local /etc/hosts

Yes,
grep -v
will do the required.
