Using ECHO in .bat files

The ECHO statement has two separate uses:
1. It controls the display of all commands in your .bat file.
2. Display information you want

Controlling the display of commands

Most .bat files you will see start with the following line of code:

		 @echo off

This causes the command interpreter (command.com or cmd.exe), to suppress the display of all following commands in your .bat file.
The @, that can be used on any line in your .bat file, causes the interpreter to also suppress the display of the "echo off" line.
Try to run the following .bat file

		 REM @echo off
		 echo Hello

The REM statement is described here, by the way. If you run the previous lines the output will be like:

C:\Documents and Settings\Gert Rijs>REM @echo off

C:\Documents and Settings\Gert Rijs>echo Hello
Hello
C:\Documents and Settings\Gert Rijs>

So, you see every line of your .bat file printed as it runs. This can be very nice if you are writing a new .bat file, you can see all output and errors as it is run. When you are finished writing, you might like the output to be slightly less cluttered.
Remove the REM from the first line, so your .bat file looks like:

@echo off
echo Hello

Now run it again, your output should resemble:

Hello
