How do I see who's logged in?

Question

I'm having a little problem. I need to (from the command line) be able to see what users are logged in.

Here's the tricky part: I DO NOT want those users that have locked their screens and left their desktop to show up in my list.

I've tried doing these two things, but both of them show users that have locked desktops. Is there anything else I can do?

Answer 1

who -Hu

will provide you a list of logged in users, and their idle times.

who -u

will forego printing the headers. To know whether it will report correctly for screen-locked users, I guess you'll have to test it. Here's the output from my system right now:

[mini-nevie:~] nevinwilliams% /usr/bin/who -Hu
USER          LINE     WHEN         IDLE       PID  COMMENT
nevinwilliams console  Apr 18 01:27  old        62
nevinwilliams ttys000  Apr 20 14:34 00:08    31675
nevinwilliams ttys001  Apr 20 14:35 00:04    31695
nevinwilliams ttys002  Apr 20 14:42   .      31758
[mini-nevie:~] nevinwilliams%

I ran the command from ttys002.
