NAME
ps - report process status
SYNOPSIS
ps [options]
DESCRIPTION
ps gives a snapshot of the current processes. If you want a repetitive
update of this status, use top. This man page documents the /proc-based
version of ps, or tries to.
COMMAND-LINE OPTIONS
This version of ps accepts several kinds of options.
Unix98 options may be grouped and must be preceeded by a dash.
BSD options may be grouped and must not be used with a dash.
GNU long options are preceeded by two dashes.
Options of different types may be freely mixed.
Set the I_WANT_A_BROKEN_PS environment variable to force BSD syntax
even when options are preceeded by a dash. The PS_PERSONALITY environ-
ment variable (described below) provides more detailed control of ps
behavior.
SIMPLE PROCESS SELECTION
Switch Description
() ()
-A select all processes
-N negate selection
-a select all with a tty except session leaders
-d select all, but omit session leaders
-e select all processes
T select all processes on this terminal
a select all processes on a terminal, includ-
ing those of other users
g really all, even group leaders (does nothing
w/o SunOS settings)
r restrict output to running processes
x select processes without controlling ttys
--deselect negate selection

STANDARDS
This ps can be set to conform to version 2 of the Single Unix Specifi-
cation.
AUTHOR
ps was originally written by Branko Lankester .
Michael K. Johnson re-wrote it significantly to
use the proc filesystem, changing a few things in the process.
Michael Shields added the pid-list feature.
Charles Blake added multi-level sorting, the dirent-
style library, the device name-to-number mmaped database, the approxi-
mate binary search directly on System.map, and many code and documenta-
tion cleanups.
David Mosberger-Tang wrote the generic BFD support for psupdate.
Albert Cahalan rewrote ps for full Unix98 and BSD
support, along with some ugly hacks for obsolete and foreign syntax.
Michael K. Johnson is the current maintainer.
