expect 脚本同步文件,指定host和要同步的文件,构建文件分发系统,批量远程执行命令

expect脚本自动同步文件

#!/usr/bin/expect

set passwd "1q2w3e"

spawn rsync -av [email protected]:/tmp/12.txt /tmp/

expect {

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

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

}

expect eof

如果尝试取消最后一行,expect eof

会出现,还没输入密码就退出的情况

指定host和要同步的文件,从本机到对方

set host [lindex $argv 0]

set file [lindex $argv 1]

spawn rsync -av $file root@$host:$file

文件分发系统的实现

rsync.expect 内容

spawn rsync -aRv $file root@$host:$file

ip.list内容

[root@aminglinux01 sbin]# cat /tmp/ip.list

192.168.67.129

192.168.67.130

127.0.0.1

file.txt内容

[root@aminglinux01 sbin]# cat /tmp/file.txt

/tmp/12.txt

/root/shell/1.sh

/root/111/222/lll.txt

rsync.sh 内容

[root@aminglinux01 sbin]# cat rsync.sh

#!/bin/bash

for ip in 'cat /tmp/ip.list'

do

./rsync.expect $ip /tmp/file.txt

done

出现问题,暂未解决

expect 脚本同步文件,指定host和要同步的文件,构建文件分发系统,批量远程执行命令

发现问题点,修改标点符号,即可。忘了

的作用了<br/>#!/bin/bash<br/>for ip in

cat /tmp/ip.list` * 注意:就是这两个不是单引号的标点符号

实验结果:

[root@aminglinux01 sbin]# sh -x rsync.sh

++ cat /tmp/ip.list

  • for ip in '

    cat /tmp/ip.list

    '
  • ./rsync.expect 192.168.67.129 /tmp/file.txt

    spawn rsync -avR --files-from=/tmp/file.txt / [email protected]:/

验证之后发现 文件同步到67.130上了

再同步一次就成功了
