Commands Reference, Volume 4

rwho Command


Shows which users are logged in to hosts on the local network.


rwho-a ]


The /usr/bin/rwho command displays the user name, host name, and start date and time of each session for everyone on the local network who is currently logged in to a host running the rwhod daemon. If a workstation is inactive for at least 3 minutes, the rwho command reports the idle time as a number of minutes in the last column. After an hour of inactivity, a user is not included unless the -a flag is specified.

Note: Since this command displays a lot of output, use this command with caution if the local network has a large number of users.

Status information is broadcast once every 3 minutes by each network host running the rwhod daemon. Any activity (such as a user logging on or off) that takes place between broadcasts is not reflected until the next broadcast.


-a Includes all users. Without this flag, users whose sessions are idle an hour or more are not included in the report.


To get a report of all users currently logged in to hosts on the local network, enter:
