1,查看远程登录用户和定位到自己是哪一个终端
[[emailprotected] worker]# w
15:27:07 up 300 days, 4:18, 4 users, load average: 0.07, 0.15, 0.11
USER TTY FROM [emailprotected] IDLE JCPU PCPU WHAT
worker pts/2 182.150.44.71 15:08 0.00s 0.03s 0.02s sshd: worker [priv]
worker pts/3 182.150.44.71 15:08 17:33 0.00s 0.02s sshd: worker [priv]
worker pts/5 182.150.44.71 15:26 9.00s 0.00s 0.00s -bash
worker pts/6 182.150.44.71 15:26 8.00s 0.00s 0.00s -bash
[[emailprotected] worker]# who am i
worker pts/2 -10-09 15:08 (182.150.56.79)
2，发送消息给要关闭的终端用户
[[emailprotected] worker]# echo -e "i will close your connection in one minute,please contack devops in time" >/dev/pts/3
对方收到的信息如下：
[[emailprotected] worker]# who am i
worker pts/3 -10-09 15:08 (182.150.56.79)
[[emailprotected] worker]# i will close your connection in one minute,please contack devops in time
3，关闭某一个远程登录终端
[[emailprotected] worker]# fuser -k /dev/pts/3
/dev/pts/3: 30355 30408 30409
重新w查看，3的终端已经不在了。
[[emailprotected] worker]# w
15:31:40 up 300 days, 4:22, 3 users, load average: 0.19, 0.16, 0.11
USER TTY FROM [emailprotected] IDLE JCPU PCPU WHAT
worker pts/2 182.150.44.71 15:08 0.00s 0.03s 0.02s sshd: worker [priv]
worker pts/5 182.150.44.71 15:26 4:42 0.00s 0.00s -bash
worker pts/6 182.150.44.71 15:26 4:41 0.00s 0.00s -bash
