-By default, \fBps\fR selects all processes with the same effective user
-ID (EUID) as the curent user and associated with the same terminal as the
-invoker. It displays the process ID (PID), the terminal (tty) associated
-with the process (TTY), the cumulated CPU time in [dd\-]hh:mm:ss format
-(TIME), and the executable name (CMD). The use of BSD\-style options
-will add process state (STAT) to the default display. The use of BSD\-style
-options will also change the process selection to include processes
-on other terminals (TTYs) that are owned by you; alternately, this may
-be described as setting the selection to be the set of all processes
-filtered to exclude processes owned by other users or not on a terminal.
-Output is unsorted by default.
