Not really: the function `:` calls itself and _pipes_ into itself. The difference is - from what I can deduce - that if it were to only call itself, there would be up to 2 `:` processes running at a time, while the bash call stack would grow indefinitely. Using all your RAM but not an actual fork bomb. Adding the pipe makes the number of `:` processes grow exponentially, and very quickly you reach the limit of 16384 active processes (PIDs, actually) on a Linux box. |
