Editing Shutting Down Services (section)

=== What is Running? ===

After setting-up superuser access and the ability to run the computer in single user mode, one can begin on disabling unnecessary background processes. But the key here is to keep the system running without disrupting the services that allows the computer to function properly. To do this, start by listing all of the processes running on the computer using the command ''ps wwwaux''. The "ps" program (short for process status) allows the user to display currently running processes.

From Example A (above), several samples of running processes can be seen. The system processes that will not be touched have brackets surrounding the name. For instance, Example A's '''Command Column''' has ''[Migration/0]'' and several other system processes that we will not be shutting down. However, not all processes are essential for the purposes of this experiment. Some services, those that are unbracketed, may be turned off and still allow the computer to function properly.
