expect管理N多服务器

一个很简单的例子，下次有机会慢慢扩展^_^

#!/usr/bin/expect

set timeout -1

set host [lindex $argv 0]
set user [lindex $argv 1]
set pass [lindex $argv 2]

spawn telnet $host
expect *login:

send "$user\r"
expect *assword

send "$pass\r"
expect *bude243

send "ls -l > ls.out\r"
send "exit\r"
expect eof
