Linux Terminates user sessions

The first step is to use the TTY command to view your session ID, in this case the session ID is 1
[[email protected] ~]# TTY
/dev/pts/1
[Email protected] ~]#

The second step uses the W command to see which sessions the current server has;
[Email protected]:~$ W
10:14:59 up min, 2 users, Load average:0.00, 0.09, 0.27
USER TTY from [email protected] IDLE jcpu PCPU
Dante Pts/1 192.168.1.2 10:14 0.00s 0.54s 0.00s W
Dante pts/0 192.168.1.120 10:10 4:29 0.55s 0.55s-bash
[Email protected]:~$

Step three use the Pkill command to kill the corresponding session ID
[Email protected]:~$ pkill-9-T pts/0
[Email protected]:~$ W
10:17:35 up min, 1 user, load average:0.01, 0.07, 0.23
USER TTY from [email protected] IDLE jcpu PCPU
Dante Pts/1 192.168.1.2 10:14 0.00s 0.58s 0.00s W
