Ps (Unix)

In most Unix-like operating systems, the ps command line program gives a snapshot of the currently running processes, including ps itself.

ps has many options, though it is commonly run with the options aux, where "a" lists all processes on a terminal, including those of other users, "x" lists all processes without controlling terminals and "u" adds the controlling user for each process.
