用expect实现的自动登录到多台服务器的shell脚本

复制代码

代码如下:

#!/usr/bin/expect -f

set ipaddress [lindex $argv 0]

set passwd [lindex $argv 1]

set timeout 30

spawn ssh root@$ipaddress

#expect “yes/no”

#send “yesr”

expect “password:”

send “$passwdr”

expect “]*”

send “mkdir -p /tmp/haha/haha2r”

send “exitr”

***************

expect {

“(yes/no)?” {

     send “yesn”

  }

“password:” {

   ….

}

判断语句

if {$havepass == 0} {

  expect “password:” { send “$pwn” }

}

或者：

expect {

“yes/no” { send “yesr”; exp_continue}

“password:” { send “$passwdr” }

}
