Loops Expect脚本在foreach循环中失败

我有一个expect脚本，它在一个包含主机列表的文件中循环，ssh进入每个主机，sudo进入根目录，并运行id。问题是它永远不会返回到源服务器外壳。它试图从它已使用ssh连接到的主机上运行，从而弄乱了逻辑

set file [open "hosts.test"]
set hosts [split [read -nonewline $file] "\n"]
close $file

foreach host $hosts {
    puts $host
    spawn ssh -q -o StrictHostKeyChecking=no  [lindex $argv 0]@$host
    expect "Password: "
    send "[lindex $argv 1]\r"
    expect -re "(>|#) "
    send "sudo su -\r"
    expect "Enter YOUR password: "
    send "[lindex $argv 1]\r"
    expect -re "(>|#) "
    send "id\r"
    expect -re "(>|#) "
    send "exit\r"
    expect -re "(>|#) "
    send "logout\r"
    close $spawn_id
 }

以下是错误：

看起来你输入了错误的登录密码。我在这里更改了明文密码。这不是问题，问题是它永远不会返回到源服务器。它尝试从它登录的第一台服务器再次生成，因此它永远不会返回到它期望在脚本中使用的原始shell。查看调试输出，我看到相同的密码：prompt repeated。我的结论是密码没有正确发送。您是否看到所有超时消息？
