| .B w \- |
| .RB [ husfV ] |
| .RI [ user ] |
| .SH DESCRIPTION |
| .B "w " |
| displays information about the users currently on the machine, |
| and their processes. |
| The header shows, in this order, the current time, |
| how long the system has been running, |
| how many users are currently logged on, |
| and the system load averages for the past 1, 5, and 15 minutes. |
| .sp |
| The following entries are displayed for each user: |
| login name, the tty name, the remote host, login time, idle time, JCPU, PCPU, |
| and the command line of their current process. |
| .sp |
| The JCPU time is the time used by all processes attached to the tty. It |
| does not include past background jobs, but does include currently |
| running background jobs. |
| .sp |
| The PCPU time is the time used by the current process, named in the "what" |
| field. |
