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.
