Difference between interact, expect and exit in expect script
<p>I have a expect script as follow.</p>

<pre><code>#!/usr/bin/expect

set timeout 20

spawn "some_script.sh"

expect "Enter Auth Username:"
send "username\n"

expect "Enter Auth Password:"
send "password\n"

expect/interact/exit
</code></pre>

<p>I would like to know what is different between using expect/interact/exit.</p>

<p>Thanks!</p>
