$ w

 20:01:30 up 6 days,  2:20,  3 users,  load average: 0.06, 0.11, 0.10
USER     TTY      FROM             LOGIN@   IDLE   JCPU   PCPU WHAT
rick     tty7     :0               16Jun20  6days 16:51   2.37s /sbin/upstart --user
rick     pts/21     18:44    1:14m  0.19s  0.00s sleep 60
rick     pts/22     18:45    0.00s  0.44s  0.01s w
