rwho — show who is logged in on local machines


rwho [-a]


rwho produces output similar to the output of the HP-UX who command for all machines on the local network that are running the rwho daemon (see who(1) and rwhod(1M)). If rwhod has not received a report from a machine for 11 minutes, rwho assumes the machine is down and rwho does not report users last known to be logged into that machine.

rwho's output line has fields for the name of the user, the name of the machine, the user's terminal line, the time the user logged in, and the amount of time the user has been idle. Idle time is shown as:


If a user has not typed to the system for a minute or more, rwho reports this as idle time. If a user has not typed to the system for an hour or more, the user is omitted from rwho's output unless the -a flag is given.

An example output line from rwho would look similar to:

joe_user machine1:tty0p1 Sep 12 13:28 :11

This output line could be interpreted as joe_user is logged into machine1 and his terminal line is tty0p1. joe_user has been logged on since September 12 at 13:28 (1:28 p.m.). joe_user has not typed anything into machine1 for 11 minutes.


rwho's output becomes unwieldy when the number of users for each machine on the local network running rwhod becomes large. One line of output occurs for each user on each machine on the local network that is running rwhod.


rwho was developed by the University of California, Berkeley.
