分发系统：命令批量执行脚本

该脚本实现对不同主机批量执行命令

[[email protected] ~]# cat exe.expect#!/usr/bin/expect
set host [lindex $argv 0]
set passwd "123456"
set cm [lindex $argv 1]
spawn ssh [email protected]$host
expect {
"yes/no" { send "yes\r"}
"password:" { send "$passwd\r" }
}
expect "]*"
send "$cm\r"
expect "]*"
send "exit\r"

[[email protected] ~]# cat exe.sh#!/bin/bash
for ip in `cat ip.txt`
do
    echo $ip
    ./exe.expect $ip ‘w ; free -m ; ls /tmp"
done

[[email protected] ~]# cat ip.txt
