rwho(1C)

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 user 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.
