1.首先查看已经登陆的用户
|
1 2 3 4 5 6 |
[root@VM_152_184_centos /]# w 20:50:14 up 9 days, 5:58, 3 users, load average: 0.21, 0.05, 0.02 USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT root pts/0 101.45.224.253 20:48 0.00s 0.00s 0.00s w root pts/1 101.45.224.253 20:49 17.00s 0.00s 0.00s -bash test pts/2 101.45.224.253 20:50 2.00s 0.00s 0.00s -bash |
用w命令可以看出，现在登陆的账号有root和hmj两位
2.踢掉test的登陆
踢掉test用户的登陆，实际上就是杀死它的进程。
执行命令：
|
1 |
pkill -kill -t TTY值 |
|
1 |
<fieldset>例如：pkill -kill -t pst/2</fieldset> |
3.再用w命令查看已经登录的用户
|
1 2 3 4 5 |
[root@VM_152_184_centos /]# w 20:55:10 up 9 days, 6:03, 2 users, load average: 0.03, 0.03, 0.00 USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT root pts/0 101.45.224.253 20:48 0.00s 0.00s 0.00s w root pts/1 101.45.224.253 20:49 5:13 0.00s 0.00s -bash |
此时可以看到，用户test已经被踢出去了。
