At some point the Linux kernel will be patched to detect and terminate forking attacks, and sadly all these memes will be dead.
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.
That’s why I run all my terminal commands through ChatGPT to verify they aren’t some sort of fork bomb. My system is unusably slow, but it’s AI protected, futuristic, and super practical.
Seems inefficient, one should just integrate ChatGPT into Bash to automatically check these things.
You said ‘ls’ but did you really mean ‘ls -la’? Imma go ahead and just give you the output from ‘cat /dev/urandom’ anyway.
I said “ls” but I really meant “sl”. I just wanted to watch that steam locomotive animation.
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.
The thing about fork bombs that it’s not particular process which takes up all the resources, they’re all doing nothing in a minimal amount of space. You could say “ok this group of processes is using a lot of resources” and kill it but then you’re probably going to take down the whole user session as the starting point is not trivial to establish. Though I guess you could just kill all shells connected to the fork morass, won’t fix the general case but it’s a start. OTOH I don’t think kernel devs are keen on special-case solutions.
You don’t really have to kill every process, limiting spawning of new usermode processes after a limit has been reached should be enough, combine that with a warning and always reserving enouh resources for the kernel and critically important processes to remain working and the user should have all the tools needed to find what is causing the issue and kill the responsible processes
While nobody really cares enough to fix these kinds of problems for your basic home computer, I think this problem is mostly solved for cloud/virtualization providers
Just set your ulimit to a reasonable number of processes per user and you’ll be fine.
If you’re cold, they’re cold.
Run this command to warm up your computery friends.
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.
Ah yes. Uni(x bomb)
How did this one work again? It was something with piping in a backgrounded subshell, right?
It creates a new process that spins up 2 new instances of itself recursively.

Thanks, nice Infographic!
Hard to pronounce but ok I guess.
It’s pronounced “forky”.

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.
Mine had the text “you are won solitaire” on them
I like your style. How often have you been cursed at?
What for those of us who are dumb but not curious?
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.Does the added “amp” do anything more in the function? I’m the curious, not (entirely) dumb type
It’s a failed html escape sequence for &
some lemmy instances were having trouble with that for a while now. html used ampersand to encode special characters, and a regular ampersand gets encoded as &
Somehow, the decoding sometimes breaks, and we get to see it the way it is here
Good old Bobby Droptables
i wanna test what happens but im Scared to do it on a vm
enjoy:
ill just crash your pc after a while
That’s not a cat but quite obviously a rabbit.
don’t do this it INSTALLS MUSTARD GAS !
nix run nixpkgs#mustard-gas
sudo apt-get install mustard-gas
It’s found at
sudo snap install mustard-gas
nowadaysNO
On a modern system it shouldn’t be that affected if you configure it right
Sudo fuck my system. There. Got it.
You laugh but you can configure a hard limit on forks.
This cat is just :3

Does it work on fish shell?
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.
The ampersand looks very weird in that font. It would bug me.
It hails back to the early days of the ampersand, from when it was basically still just Latin “et”: https://commons.wikimedia.org/wiki/File:Trebuchet_MS_ampersand.svg
Personally, I do like this font (Fira Mono+Sans), because it still looks professional, without being so boring that I get depression from looking at it.
But yeah, that ampersand is pushing it a bit, as I’m not sure everyone else knows that’s an ampersand…
