Start line parameters

[Magnum]

What does the start line do ?

I know start can open a program in another window.

@echo off
:: A fork bomb using the Microsoft Windows batch language:
:: WARNING !! THIS LOCKS UP YOUR SYSTEM !!!
:s
start "" %0
goto s

%0 in a batch file is the name of the file itself, %1 etc. are the parameters.

Code Select Expand

@echo off
:: A fork bomb using the Microsoft Windows batch language:
:: WARNING !! THIS LOCKS UP YOUR SYSTEM !!!
:s
start "" %0
goto s

Opens a new window every round, those windows open a new window every round and so on.
Won't "lock up your system" but you would never be quick enough to kill them. Just restart, no drama.

Obviously, I am not going to try.

In XP, it does indeed lock up your system.

Even CAD won't help.

That's why it is called a fork bomb. :-)

What O.S. are you running ?
