rwho

rwho(1) 						      General Commands Manual							   rwho(1)

NAME

       rwho - Shows which users are logged into hosts on the local network.

SYNOPSIS

       rwho [-a]

       rwho [-a] [users]

OPTIONS

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

DESCRIPTION

       The  rwho  command  displays  the username, hostname, and start date and time of each session for everyone on the local network who is cur-
       rently logged in to a host running the rwhod daemon.

       If one or more user names are specified, only the status of those users whose names are listed appears on the screen. If  a  user  has  not
       typed  anything for at least 3 minutes, rwho 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 option is specified. Because 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.

EXAMPLES

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

       $ rwho

       bob		host2:pts5		 Nov  17  06:30   :20	bob		  host7:console 	    Nov   17   06:25   :25   franz
       host1:pts0		Nov  17  11:20	:51  franz	      host1:pts8	       Nov  16	15:33  :42  franz	     host4:console
       Nov 17 16:32 pietro	    host1:console	    Nov 17 13:14 :31 pietro	      host1:pts7	       Nov  17	13:15  :47  server
       host2:console	       Nov 17 06:58 :20 luis		host2:pts6		Nov 17 09:22

FILES

       Indicates data files received from remote rwhod daemons.
