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
environment variable (described below) provides more detailed control of
ps behavior.
