　　强制踢人命令格式：pkill -kill -t pts
　　解释：
　　pkill -kill -t 　踢人命令
　　tty　所踢用户的TTY
　　如上踢出tty1用户的命令为： pkill -kill -t pts/4
　　用户已经被强制踢掉了

实践如下：
1）谁还在用ssh连接到本linux上？
[root@iZ25dcp92ckZ ~]# w
17:52:38 up 118 days,  1:38,  5 users,  load average: 2.01, 2.02, 2.05
USER     TTY      FROM             LOGIN@   IDLE   JCPU   PCPU WHAT
root     pts/0    202.108.16.80    09:36    2:45m  1:36   0.34s -bash
root     pts/1    202.108.16.80    09:36    2:45m  0.19s  0.19s -bash
root     pts/3    202.108.16.80    09:36    2:45m  0.26s  0.26s -bash
root     pts/9    202.108.16.80    09:40    3:48m  0.11s  0.11s -bash

2）根据1作pkill操作，自己的ssh连接得留下：
[root@iZ25dcp92ckZ ~]# pkill -kill -t pts/0
[root@iZ25dcp92ckZ ~]# pkill -kill -t pts/1
[root@iZ25dcp92ckZ ~]# pkill -kill -t pts/3
[root@iZ25dcp92ckZ ~]# pkill -kill -t pts/9

3）确认已经把pc的ssh连接杀死并Ok了：
[root@iZ25dcp92ckZ ~]# w
17:53:21 up 118 days,  1:39,  1 user,  load average: 1.44, 1.89, 2.00
USER     TTY      FROM             LOGIN@   IDLE   JCPU   PCPU WHAT
root     pts/10   117.136.0.88     17:32    1.00s  0.05s  0.00s w
[root@iZ25dcp92ckZ ~]#
