title: How does the echo command works in batch programming
body: <p>I'm have started to learn batch programming to go a little more deeper in the Windows Machines. In Internet I have seen some commands with echo like <strong>"@echo off"</strong> or <strong>"on"</strong> and also this: <strong>"echo."</strong> but I don't know what are they doing. If anyone can explain me the functions of the echo command, please answer me.</p>
