These 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.
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).
