options are used to choose the information displayed by ps. The
output may differ by personality.
-c Show different scheduler information for the -l option.
--context
Display security context format (for SELinux).
-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.
-F Extra full format. See the -f option, which -F implies.
--format format
user-defined format. Identical to -o and o.
j BSD job control format.
-j Jobs format.
l Display BSD long format.
-l Long format. The -y option is often useful with this.
-M Add a column of security data. Identical to Z (for SELinux).
O format
is preloaded o (overloaded). The BSD O option can act like -O
(user-defined output format with some common fields predefined)
or can be used to specify sort order. Heuristics are used to
determine the behavior of this option. To ensure that the
desired behavior is obtained (sorting or formatting), specify the
option in some other way (e.g. with -O or --sort). When used as
a formatting option, it is identical to -O, with the BSD
personality.
-O format
Like -o, but preloaded with some default columns. Identical to
-o pid,format,state,tname,time,command or -o pid,format,tname,
time,cmd, see -o below.
o format
Specify user-defined format. Identical to -o and --format.
-o format
User-defined format. format is a single argument in the form of
a blank-separated or comma-separated list, which offers a way to
specify individual output columns. The recognized keywords are
described in the STANDARD FORMAT SPECIFIERS section below.
Headers may be renamed (ps -o pid,ruser=RealUser -o comm=Command)
as desired. If all column headers are empty (ps -o pid= -o
comm=) then the header line will not be output. Column width
will increase as needed for wide headers; this may be used to
widen up columns such as WCHAN (ps -o pid,wchan=WIDE-WCHAN-COLUMN
-o comm). Explicit width control (ps opid,wchan:42,cmd) is
offered too. The behavior of ps ‐o pid=X,comm=Y varies with
personality; output may be one column named "X,comm=Y" or two
columns named "X" and "Y". Use multiple -o options when in
doubt. Use the PS_FORMAT environment variable to specify a
default as desired; DefSysV and DefBSD are macros that may be
used to choose the default UNIX or BSD columns.
-P Add a column showing psr.
s Display signal format.
u Display user-oriented format.
v Display virtual memory format.
X Register format.
-y Do not show flags; show rss in place of addr. This option can
only be used with -l.
Z Add a column of security data. Identical to -M (for SELinux).
OUTPUT MODIFIERS
c Show the true command name. This is derived from the name of the
executable file, rather than from the argv value. Command
arguments and any modifications to them are thus not shown. This
option effectively turns the args format keyword
