Batch: echo ON (or) OFF


‘echo’ command display messages, or turns command-echoing on or off.

Syntax
ECHO [ON | OFF]
ECHO [message]

By default, echo is on. You can test this by executing echo command in command prompt.

C:\>echo
ECHO is on.

Why do we require ‘echo off’?
Hello.bat
ver
vol
cd

When you ran Hello.bat file, it prints the commands names also in the output.



You can display the output without command names using echo off command.

Hello.bat

@echo off
ver
vol
cd
