rwho

rwho(1) 						      General Commands Manual							   rwho(1)

NAME

       rwho - show who is logged in on local machines

SYNOPSIS

DESCRIPTION

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

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

       An example output line from would look similar to:

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

WARNINGS

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