一个用expect批量登陆主机执行命令的脚本

主机文件如下:

host.txt

192.168.10.1   host1

192.168.10.2   host2

192.168.10.3   host3

192.168.10.4   host4

192.168.10.5   host5


expect 脚本如下

# login.exp

#!/usr/bin/expect -f

set ipaddress [lindex $argv 0]

set password [lindex $argv 1]

set CMD [lindex $argv 2]

spawn ssh $ipaddress $CMD

expect "(yes/no)"{

    send "yes\r"

    expect "password:"

    send "$password\r"

    }

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

    "*host" {exit 1}

expect eof


批量执行脚本如下(打印出所有的主机名)：

#!/bin/bash

for i in $(awk -F\  '{print $1}' host.txt)

do

./login.exp $i test1 hostname

done
