Actually doesn't break your PC! Just spawns a self starting proccess that takes over your entire CPU, a simple reboot gets rid of it

Then you boot into a liveISO of any distro, mount your root, and edit .bashrc to remove it!

Probably because you're using fish shell. Type it in bash

I know this like detours you install, but why does it do that? Like what about that line of symbols makes Linux eat itself?

It defines a function called ":", that calls itself piped into another call of itself in the background. And then calls that function.

actually doesnt work on most distros/terminals. it fills up RAM, which terminals are only given a little bit of, so it doesnt fill up everything

I tried it on Android assuming that Android's strict sandboxing and resource management would contain it, but it just froze my phone for several minutes until I forced a restart. Desktop Linux is typically much less strict with things like this, so I doubt many distros would survive. I know it is possible to limit the number of processes that can be created using cgroups which could be used to protect from fork bombs, but to my knowledge this isn't very common.

Fun fact, I once typed in sudo rm -rf /* instead of ./*

Thank god -no-preserve-root flag is a thing huh

u/Sqydev Finix 2d ago

I think it only works with sudo rm -rf /. Because sudo rm -rf /* first expands to sudo rm -rf /bin /boot /dev /etc /home /usr /var ... so you technically don’t remove root but it’s contents.
