Log Everyone Out Of The System
If you want to log out all other users in a system, you can use pkill command.
who or w command - Show who is logged on and what they are doing.
pkill command - Kill user session and forcefully logout of the system.
For Example :
==========
root@vps [~]# w
root pts/0 * 00:17 4:43m 0.04s 0.04s -bash
test pts/4 * 05:04 3.00s 0.00s 0.00s -bash
root@vps [~]# pkill -KILL -u test
root@vps [~]# w
root pts/0 * 00:17 4:45m 0.06s 0.06s -bash
==========
OR you can run below script.
who | awk '!/root/{ cmd="/sbin/pkill -KILL -u " $1; system(cmd)}'
Note : You have to run above script as root
