How to forcefully kick out a logged-in user in centos system

In the system, we can use w or who to view the user:

[root@linuxidc ~]# who
root pts/0 2019-04-17 20:45 (58.63.138.162)
root pts/1 2019-05-5 22:24 (118.186.197.221)
 
[root@linuxidc ~]# w
22:33:29 up 4 days, 8:05, 2 users, load average: 1.58, 1.36, 1.47
USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT
root pts/0 58.63.138.162 20:45 0.00s 0.03s 0.00s w
root pts/1 118.186.197.221 22:24 4:40 0.02s 0.02s -bash

See which user is logged in:

(recommended tutorial : centos usage tutorial)

[root@linuxidc ~]# who am i
root pts/0 2019-04-17 20:45 (58.63.138.162)

Next use pkill to kick out user pts/1:

[root@linuxidc ~]# pkill -kill -t pts/1

Then use w or who to view:

[root@linuxidc ~]# w
22:40:43 up 4 days, 8:12, 1 user, load average: 1.58, 1.36, 1.40
USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT
root pts/0 58.63.138.162 20:45 0.00s 0.03s 0.00s w

There are no more pts/1, you're done.
