What does “@” mean in Windows batch scripts

Question

I saw @ is used in such contexts:

@echo off

@echo start eclipse.exe

What does @ mean here?

Answer 1

Another useful time to include @ is when you use FOR in the command line. For example:

FOR %F IN (*.*) DO ECHO %F

Previous line show for every file: the command prompt, the ECHO command, and the result of ECHO command. This way:

FOR %F IN (*.*) DO @ECHO %F

Just the result of ECHO command is shown.
