NAME
rwho - who’s logged in on local machines

SYNOPSIS
rwho [ -a ]

DESCRIPTION
The rwho command produces output similar to who, but for all
machines on the local network. If no report has been received from
a machine for 5 minutes then rwho assumes the machine is down, and
does not report users last known to be logged into that machine.

If a users hasn’t typed to the system for a minute or more, then
rwho reports this idle time. If a user hasn’t typed to the system
for an hour or more, then the user will be omitted from the output
of rwho unless the -a flag is given.

FILES
/usr/spool/rwho/whod.* information about other machines

BUGS
This is unwieldy when the number of machines on the local net is
large.
