report a snapshot of the current processes

-e              Select all processes. Identical to -A.

-f              Do full-format listing. This option can be combined with many other UNIX-style options to
                add additional columns. It also causes the command arguments to be printed. When used
                with -L, the NLWP (number of threads) and LWP (thread ID) columns will be added. See the
                c option, the format keyword args, and the format keyword comm.

-d              Select all processes except session leaders.

x               Lift the BSD-style "must have a tty" restriction, which is imposed upon the set of all
                processes when some BSD-style (without "-") options are used or when the ps personality
                setting is BSD-like. The set of processes selected in this manner is in addition to the
                set of processes selected by other means. An alternate description is that this option
                causes ps to list all processes owned by you (same EUID as ps), or to list all processes
                when used together with the a option.

-a              Select all processes except both session leaders (see getsid(2)) and processes not
                associated with a terminal.

r               Restrict the selection to only running processes.

g               Really all, even session leaders. This flag is obsolete and may be discontinued in a
                future release. It is normally implied by the a flag, and is only useful when operating
                in the sunos4 personality.
