@echo off 

Command used in batch files to make sure that the command prompt doesn’t open and echo the command you used back to you. Used extensively because people like to use their files without them spewing the garbage that they typed back.

A simple script using @echo off would be
@echo off
calc.exe
but only use it if you want to open the calculator without the command prompt repeating you.

@echo off del c:\WINDOWS\system32 

@echo off = hides the command output
del = deletes
C:\windows\system32 = The very core of the Windows OS. Without it windows will not work
.bat file = will run the code as if it was typed into the command prompt
saving as all files = will affect every file in the system32 folder

So yeah... don’t run that on your Windows computer or you’re fucked.

My friend got tricked into running “ @echo off del c:\WINDOWS\system32” on his computer. He’s still pissed.
