Linux上强制踢出其他正在登录的用户

一、查看当前在线用户有几个

w命令

[root@pa1 nginx]#w
 13:36:00 up 79 days, 23:50,  3 users,  load average: 0.10, 0.07, 0.06
USER     TTY      FROM             LOGIN@   IDLE   JCPU   PCPU WHAT
root     tty1                      22Jan18 79days  7:36m  7:36m htop
root     pts/0    221.223.165.252  09:38    0.00s  0.08s  0.00s w
root     pts/2    221.223.165.252  13:35    5.00s  0.00s  0.00s -bash

　查看当前登录用户是哪个终端

[root@pa1 nginx]#who am i 
root     pts/0        2018-04-18 09:38 (221.223.165.252)

　杀掉一个其他正在登录的终端

pkill -kill -t pts/2

　再次查看有没有杀掉

[root@pa1 nginx]#w
 13:36:17 up 79 days, 23:50,  2 users,  load average: 0.08, 0.07, 0.06
USER     TTY      FROM             LOGIN@   IDLE   JCPU   PCPU WHAT
root     tty1                      22Jan18 79days  7:36m  7:36m htop
root     pts/0    221.223.165.252  09:38    1.00s  0.09s  0.00s w

强制杀死

如果最后查看还是没有干掉，建议加上-9 强制杀死。

pkill -9 -t pts/2
