Hi
I have 2 files where i save the IP adress of many printers that work on UNIX, one of these files, which is the 'Main File', is on a server call PROD, and the other one is on a different server call Al.
What I want, is to make a comparison between the 2 files, and then, copy the IPs that exist on the server PROD that are not on the Al server.
I understand that the diff command may be useful but I don't get the way yet.
Thax a lot!
