How can I get a list of users running processes?

I'm looking for a command that will give me a list of users (unique, dont name my user account 60 times) that are running processes on a system... Help?

I think that is the best reply I have ever seen.

Its also the shortest, most concise and actually contained the solution to the OP's question... in one character! Haha.

Well done.

Indeed. Very funny, except it's not what I asked for.



ps –fa | awk ‘{print NR “ ” $1}’ | sort -u

You can also use the negate switch with ps for some interesting results:

tgalati4@tpad-Gloria7 ~ $ ps -f -N -U tgalati4 -U root
