shell结合expect的非交互式脚本

简单需求来讲解shell+expect

先安装下expect，yum安装

yum install expect -y

#!/bin/bash

ip=‘192.168.80.20‘    #定义远程交换服务器的IP

password=‘[email protected]‘    #定义输入的密码

expect << EOF

spawn ssh [email protected]$ip ls    #在expect中执行命令

set timeout -1            #定义超时时间，-1为永不超时

expect "*:"                #如果输出*：

set timeout -1

send "$password\r"        #自动输入password

expect eof            #结束

EOF
