Listing users

We can check who is currently logged on to the system using the w command. This gives us some basic system statistics and list all users logged on:

  8:54pm  up 22 min,  3 users,  load average: 0.00, 0.02, 0.04
User     tty       login@  idle   JCPU   PCPU  what
jasonw   tty5      8:42pm    10                -bash
asti     tty6      8:43pm    11                (bash)
markst   ttyp2     8:32pm                      w

We can also see when the user logged on, how long he has been idle and what he is currently doing. Two of the users seem to be doing nothing as only their shell appears as their active process. The third user is actually running the w program.
