浅析Linux系统如何实现不同终端间同步的技巧
浅析Linux系统如何实现不同终端间同步的技巧: 在进行Linux多终端操作时,如果能够实现不同终端之间的同步,那么就能够在各个终端上显示相同的操作效果,能够节省很多时间,操作方法也很简单,下面小编就给大家介绍下Linux不同终端间同步的方法。
安装必须软件
#yum install tcl expect
(1)确认当前所在终端号:
root@localhost shell]# w
17:59:31 up 9:47, 5 users, load average: 0.06, 0.02, 0.00
USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT
root tty3 - 08:15 9:44m 0.75s 0.75s 。/xrgsu -a
root tty1 :0 17:08 9:47m 9.41s 9.41s /usr/bin/Xorg :
root pts/0 :0.0 17:25 0.00s 3.04s 0.00s w
root pts/1 :0.0 17:33 10:04 0.11s 0.11s bash
root pts/3 :0.0 17:39 46.00s 0.02s 0.02s /bin/bash
(2)以root用户身份向指定终端发起同步命令:
=========pts/0 向pts/1 发起操作========
[root@localhost shell]# kibitz -tty pts/1 root
asking root to type: kibitz -4010
=========pts/1 收到请求 =============
[root@localhost shell]#
Message from root@localhost.localdomain on pts/0 at 18:02 。。.
Can we talk? Run: kibitz -4010
EOF
(3)按回车,输入 kibitz -4010
[root@localhost shell]# kibitz -4010
Escape sequence is ^]
此时,pts/0 与pts/1两个终端已同步,控制任何一个终端可以在两边显示操作信息。
(4)再次查看终端状态
[root@localhost shell]# w
18:06:10 up 9:54, 5 users, load average: 0.04, 0.02, 0.00
USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT
root tty3 - 08:15 9:50m 0.76s 0.76s 。/xrgsu -a
root tty1 :0 17:08 9:54m 12.66s 12.66s /usr/bin/Xorg :
root pts/0 :0.0 17:25 1:58 5.41s 0.00s expect -- /usr/
root pts/1 :0.0 17:33 0.00s 0.11s 0.00s expect -- /usr/
root pts/3 :0.0 17:39 4:17 0.03s 0.03s /bin/bash
pts/0和pts/1已经通过expect程序同步,pts/3没有同步。
