模拟来自用户的 "enter" 按钮的命令

Question

我正在寻找一种在 tcl expect 中模拟按下 "enter" 脚本的方法（例如在一些输出之后脚本停止，并且只有在我手动按下 "enter" 之后它才会更进一步）它等待用户按下 "enter" 键，然后继续输出剩余的脚本。

这是我遇到这个问题的代码：

set timeout 20
set f [open "password.txt" r]
set password [read $f]
close $f

foreach i $password {

puts "trying this as a pass : $i"
spawn ssh user@exemple.net -p 724
expect "user@exemple.net's password:"
send $i
interact
}

此代码从 password.txt 中提取它包含的所有单词，并尝试将它们作为用户@exemple.net 的密码；代码有效，但在上面代码的这一行之后 expect "user@example.net's password:" 我需要手动按下 "enter" 按钮然后脚本继续下一次尝试。

如何模拟这个输入。有没有模拟它的命令？我是 tcl expect 的新手。谢谢你的时间。

尝试改变

send $i

至

send "$i\n"

例如使用此代码：

#!/usr/bin/expect


# Set the time allowed to wait for a given response. SEt to 30 seconds because it can take a while
# for machines to respond to an ssh request.
set timeout 30000


proc connectToServer { user host password port } {

    set address $user
    append address "@"
    append address $host

    puts "Connecting to server: $host"

    spawn ssh $address -p $port
    expect {
        {*password: } {
            send "$password\n" 
            interact
        }
        {The authenticity of host*} {
            send "yes\n"
            expect {
                {*password: } {
                    send "$password\n"
                    interact
                }
            }
        }
        "*No route to host" { puts "No route to host" }
        eof {puts "Woops there was an eof"}
        timeout {puts "Timed out"}
    }
}


if {$argc < 3} {
    puts "Error - you need to provide at least 3 arguments"
    puts "* user"
    puts "* host"
    puts "* password"
    puts "* port - optional"
} else {
    set user [lindex $argv 0];
    set host [lindex $argv 1];
    set password [lindex $argv 2];

    # setting port argument is optional
    if {$argc > 3} {
        set port [lindex $argv 3];
    } else {
        set port 22
    }

    connectToServer $user $host $password $port
}
