@echo off

One of my office mate (echo) was creating some batchfile when suddenly one of co-employee ask why his batchfile wouldnt work.

He told to echo that he is using his name as variable on batchfile just like echo is doing. And he demonstrated that he uses “@ryan off” but simply not working, while echo’s “@echo off” is working fine.

Of course we look at him grinning and explain that @echo is a command in DOS which by coincidence is echo is using.

When your echo is on, it will display each line of code on the screen but when your echo is off, it will only display the command output on the screen.
