expect批量执行命令

今天在网上发现了一个expect批量执行命令的脚本,比我之前的批量修改密码的脚本要简单些,现在共享给大家.
系统:centos
需要的软件包:expect(有网的自己yum安装,没网的在光盘里找吧)
1、定义主机ip
cat ip.txt
192.168.0.192
192.168.0.193
192.168.0.194
192.168.0.195
192.168.0.196

2、定义脚本内容
cat script.sh
mkdir test_directory

3、shell嵌套expect脚本
cat shut.sh

view source

print?

01	#!/bin/bash

02	#Create By : www.rootop.org

03	#Version : 1.0

04	#Data : 2015/05/22

05	#Last Modify: 2015/05/22-m1

06	#Desc : auto ops

07	#Tested : RedHat6/CentOS6 with "expect" package

09	passwd='123456'

10	sc=$(cat script.sh)

12	cat ip.txt \| while read line

15	/usr/bin/expect <<EOF

16	set timeout 30

17	spawn ssh root@$line

expect {

19	"yes/no" { send "yes\r";exp_continue }

20	"password:" { send "$passwd\r" }

}

22	expect "]# "

23	send "$sc\r"

24	send "exit\r"

25	expect eof

EOF

done

exit 0

ps:首先定义密码为passwd变量,把发送的命令定义为sc变量,然后用循环读ip地址定义为line变量.
