shell调用expect

expect的作用不再累述

 

下面是一个简单的shell调用expect脚本的例子

作用是从一个普通用户切换到root用户并做相关操作(删除root家目录下的myfile),然后切换回来

 

shell 脚本:  test.sh

 

#!/bin/sh

echo "test expect"


User=root
Passwd=mypass
File=myfile


./my.exp $User $Passwd $File


echo "test end"

 

 

expect 脚本:my.exp

 

#!/usr/bin/expect -f

set User [lindex $argv 0]
set Passwd [lindex $argv 1]
set File [lindex $argv 2]

spawn su - $User
expect "*password*"
send $Passwd
send "\n"
expect "*$"
send "rm -rf $File"
send "\n"
expect "*$"
send "exit\n"

expect eof
exit
