Question

我对脚本编写非常陌生，它试图创建一个脚本来自动登录到远程服务器，而无需用户输入用户名和密码，因为脚本使用预设的用户名，服务器和密码进行代理跳转。

问题是登录成功后，当用户类型退出时，控制台上会显示此错误消息：

username@remote_server ~ $ exit
logout
Connection to remote_server closed.
expect: spawn id exp6 not open
    while executing
"expect eof "

另一个问题是，当服务器不可访问时，我不确定如何正确退出脚本。我在下面的脚本中对我的尝试发表了评论。

下面是我的脚本：

 #!/bin/bash

 #log into remote server
 clear 

 echo "Enter server name [ENTER]:" #prompt user for input
 read INPUT

 SERVER=`echo $INPUT`

 clear

 echo ""
 echo "Logging into $SERVER, please wait ............"
 echo ""
 export SERVER #export global variable to expect script

 #Take the gobal env variable from bash script above i.e. $SERVER and pass 
 it into the expect script below

 /usr/bin/expect -c '
 set password "password"

            expect ":~$"
            set timeout 10
            log_user 0
            spawn ssh -o StrictHostKeyChecking=no $env(SERVER)
            expect "user_name@proxy_jump_server*:" #preset proxy jump server username and servername. User should not see this
            send "$password\r"
            expect {
                   timeout {send_user "server is unreachable"; exit} 
                   eof { ; exit } # this is where I am not sure how to exit the code correctly if the server is unreachable
                   "* ~ $"
            }
            send "clear\r"
            log_user 1
            interact
 expect eof '

期望：生成ID exp6未打开
