20.31 expect脚本同步文件
脚本

#!/usr/bin/expect
#定义密码变量
set passwd "toor"
#利用rsync远程同步文件到本地机器
spawn rsync -av root@192.168.142.131:/tmp/12.txt /tmp/

expect {
"yes/no" { send "yes\r"}
"password:" { send "$passwd\r" }
}

expect eof

运行过程:

[root@localhost sbin]# ls /tmp/
mysql.sock                                                               systemd-private-53796ea7e4b64e7ea2e4a5f6c6322639-vgauthd.service-wxkS9c

#可以看到本地tmp下有了12.txt文件
#同步的时候必须要有rsync软件

 

expect脚本指定host和要同步的文件

脚本

#!/usr/bin/expect
#定义密码变量
set passwd "123456"
#定义host参数
set host [lindex $argv 0]
#定义文件参数
set file [lindex $argv 1]
#利用rsync本机同步到另外一条机器
spawn rsync -av $file root@$host:$file

expect {
"yes/no" { send "yes\r"}
"password:" { send "$passwd\r" }
}

expect eof

 

执行过程：

[root@localhost sbin]# echo "123" > /tmp/etc 
[root@localhost sbin]# cat /tmp/etc

set host [lindex $argv 0]
set passwd "123456"
set cm [lindex $argv 1]
spawn ssh root@$host
expect {
"yes/no" { send "yes\r"}
"password:" { send "$passwd\r" }
}
expect "]*"
send "$cm\r"
expect "]*"
send "exit\r"

shell脚本

#!/bin/bash

for ip in `cat ip.list`
do
    echo $ip
    ./exe.expect $ip "w;free -m;ls /tmp"
done
