I INSTALLED “LINUX”. BECAUSE WINDOWS IS FOR MEN WHO ASK PERMISSION TO EXIST. I CRUSHED THE INSTALLER WITH MY BARE HANDS AND NOW THE TERMINAL CALLS ME “SIR” BUT MY KERNEL KEEPS PANICKING. WHAT COMMAND MAKES THE COMPUTER SUBMIT COMPLETELY? I REFUSE TO GOOGLE

:() { # define a function named ":". : # run the function named ":" | : # pass the output to the function named ":" & # run this line in the background. }; # end of definition : # call the function ":".in case anyone was curious.
If you replace : with “loop” it becomes pretty clear. The only ‘weird’ thing is using punctuation as a function name.
it’s not just looping; every instance starts two instances of itself waiting for input. it’s basically doing
async def fork(): f = fork() await fork(await f)…except python doesn’t start the second call until its arguments are evaluated, while shell does.
