Synopsis
w [username]The w command displays the
current process running in each shell for all logged-in
users:
$ w 10:51pm up 8 days, 3:42, 8 users, load average: 0.00, 0.00, 0.00 USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT barrett pts/0 :0 Sat 2pm 27:13m 0.07s 0.07s emacs jones pts/1 host1 6Sep03 2:33m 0.74s 0.21s bash smith pts/2 host2 6Sep03 0.00s 13.35s 0.04s w
The top line is the same one printed by uptime. The columns indicate the user’s
terminal, originating host or X display (if applicable), login time,
idle time, two measures of the CPU time (run man w for details), and the current
process. Provide a username to see only that user’s
information.
For the briefest output, try w
-hfs.
