Article Contributed By :. Is going to recursively execute itself forever, quickly creating many processes and slowing the system down.

This is known as a fork bomb. It keeps splitting itself until there is no option but to restart the system. It will spawn another process using a pipe which runs a copy of the same program asynchronously. This hogs the CPU and memory, slowing down the system to a near-halt or even crash the system. For example, script. A pipe symbol will make the output or result of the first command sequence as the input for the second command sequence.

In the case of a fork bomb, there is no output, so it will simply run the second command sequence without any input. This runs itself again, but also creating another process to run the same program again with no input. But a Windows pipe creates a new process for each side of the pipe, in addition to the parent process.

The parent process can't finish until each side of the pipe terminates. So the main program with a simple pipe will have 3 processes. You can see how the bomb quickly get's out of control if each side of the pipe recursively calls the parent batch! It's a logic bomb, it keeps recreating itself and takes up all your CPU resources. It overloads your computer with too many processes and it forces it to shut down.

If you make a batch file with this in it and start it you can end it using taskmgr. You have to do this pretty quickly or your computer will be too slow to do anything.
