我正试图写一个期望脚本登录到一个pfsense路由器，并运行一些命令。我似乎无法正确匹配来自pfsense设备的多行响应，并以运行autowexpect并从那里返回时看到响应的方式正确回答它们。我认为我的脚本是在传递密码，但大墙的文字，以'输入一个选项结束：登录后看到的“”未匹配。这就是我希望运行的：

# Main script
set prompt {[$>?#]: }
puts "Connecting to pfSense router..."
spawn ssh -p $ssh_port -o StrictHostKeyChecking=no $username@$pfsense_router
expect {
    -re "assword.*:" {
        send "$password\r"
        expect $prompt
#        exp_continue
    }
   -re ".*Enter an option: " {
            send "8\r"
            expect $prompt
#            exp_continue
       }
    "/root:.*" {
        puts "SSH login successful."
        check_gateway_status $target_host
    }
    "Permission denied" {
        send_user "Authentication failed. Please check your credentials.\n"
        exit 1
    }
    timeout {
        send_user "Timeout while trying to connect to the router.\n"
        exit 1
    }
}

字符串
为了匹配看起来像这样的文本：

ssh $pfsense_ip -p 3456
Password for root@$pfsense_hostname:
KVM Guest - Netgate Device ID: fa1a75cc70c259bca849

我该如何正确地做到这一点？
