Questions tagged [ps]

ps is the UNIX command for retreiving process information.

From the Linux User's Manual:

DESCRIPTION
   ps displays information about a selection of the active processes.

By default, ps displays the current processes owned by the user executing the command and attached to the same process group as the shell that launches it. On most UNIX systems, the command
ps -A (or ps -e) will display information about all processes running on the system.
