A question for all you command line experts out there. I have a big list of email addresses that has lots of duplicates, and I want to get it down to just the list of unique addresses. I just know there must be an easy way to do this with GNU utilities, but I don't know how to do it. Can someone tell me the best way to do this?
Thanks, Jim Herrmann
