I'm looking for a command to comapre two files and pull out the duplicates.
I used to know it and I haven't been able to think of it all morning
I've looked at comm, diff, and uniq and they're not it.

Any one know of this?

Thanks,
Nate

comm or uniq should do the trick, provided the 2 files are sorted.

Hope This Helps, PH.

Sorry, I mis-worded that, what I meant to do was for it to show the duplicates.

I have 2 lists of server names we're testing and i think that we have the same server on both lists. What i need it to do is to pull out what shows up on both lists

Something like this ?
comm -12 /path/to/list1 /path/to/list2
Remember, the two lists must be sorted.

Yet another way:
sort /path/to/list1 /path/to/list2 | uniq -d
