linux 如何杀掉 tty终端

1、用w -s命令可以得到终端名，如：

[root@iZwz9fmdwtsy7wsbdhvx1uZ ~]# w -s

12:53:28 up 58 min, 5 users, load average: 0.00, 0.01, 0.05

USER TTY FROM IDLE WHAT

root pts/0 119.131.52.147 56:40 -bash

root pts/1 119.131.52.147 49:20 -bash

root pts/2 119.131.52.147 36:24 /usr/bin/python /bin/yum install gitlab-ce

root pts/3 119.131.52.147 9:36 -bash

root pts/4 119.131.52.147 0.00s w -s

2、用ps -t 命令可以得到终端的进程号

如：

[root@iZwz9fmdwtsy7wsbdhvx1uZ ~]# ps -t /dev/pts/2

PID TTY TIME CMD

9565 pts/2 00:00:00 bash

9582 pts/2 00:00:00 sudo

9583 pts/2 00:00:01 yum

3、用kill -9命令

可以将进程杀掉，以关闭终端。前提：kill命令的执行者必须是超级用户或对tty1的进程有操作权限，否则，命令会报错：Operation not permitted，如：

[root@iZwz9fmdwtsy7wsbdhvx1uZ ~]# kill -9 9583

[root@iZwz9fmdwtsy7wsbdhvx1uZ ~]# ps -t /dev/pts/2

PID TTY TIME CMD

9565 pts/2 00:00:00 bash

[root@iZwz9fmdwtsy7wsbdhvx1uZ ~]# kill -9 9565

[root@iZwz9fmdwtsy7wsbdhvx1uZ ~]# ps -t /dev/pts/2

error: TTY could not be found

Usage:

ps [options]

Try ‘ps –help
