执行： ./4.expect 192.168.11.18 /tmp/12.txt第二部分：构建文件分发系统1. 需求背景对于大公司而言，肯定时不时会有网站或者配置文件更新，而且使用的机器肯定也是好多台，少则几台，多则几十甚至上百台。所以，自动同步文件是至关重要的。2. 实现思路首先要有一台模板机器，把要分发的文件准备好，然后只要使用expect脚本批量把需要同步的文件分发到目标机器即可。3. 核心命令rsync -av --files-from=list.txt / root@host:/4. 文件分发系统的实现cat rsync.expect

#!/usr/bin/expect

set passwd ""

set host [lindex $argv ]

set file [lindex $argv ]

spawn rsync -av --files-from=$file / root@$host:/

expect {

"yes/no" { send "yes\r"}

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

}

expect eof

cat ip.list

192.168.11.18

192.168.11.19

......

cat rsync.sh

#!/bin/bash

for ip in `cat ip.list`

do

    echo $ip

    ./rsync.expect $ip list.txt

done

5. 命令批量执行脚本cat exe.expect

#!/usr/bin/expect

set host [lindex $argv ]

set passwd ""

set cm [lindex $argv ]

spawn ssh root@$host

expect {

"yes/no" { send "yes\r"}

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

}

expect "]*"

send "$cm\r"

expect "]*"

send "exit\r"

cat exe.sh

#!/bin/bash

for ip in `cat ip.list`

do

    echo $ip

    ./exe.expect $ip "w;free -m;ls /tmp"

done
