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 into the comm format keyword; it is useful with
the -f format option and with the various BSD-style format
options, which all normally display the command arguments.
See the -f option, the format keyword args, and the format
keyword comm.
--cols n
Set screen width.
--columns n
Set screen width.
--cumulative
Include some dead child process data (as a sum with the
parent).
e Show the environment after the command.
f ASCII art process hierarchy (forest).
--forest
ASCII art process tree.
h No header. (or, one header per screen in the BSD
personality). The h option is problematic. Standard BSD
ps uses this option to print a header on each page of
output, but older Linux ps uses this option to totally
disable the header. This version of ps follows the Linux
usage of not printing the header unless the BSD
personality has been selected, in which case it prints a
header on each page of output. Regardless of the current
personality, you can use the long options --headers and
--no-headers to enable printing headers each page or
disable headers entirely, respectively.
-H Show process hierarchy (forest).
--headers
Repeat header lines, one per page of output.
k spec Specify sorting order. Sorting syntax is
[+|-]key[,[+|-]key[,...]]. Choose a multi-letter key from
the STANDARD FORMAT SPECIFIERS section. The "+" is
optional since default direction is increasing numerical
or lexicographic order. Identical to --sort.
Examples:
ps jaxkuid,-ppid,+pid
ps axk comm o comm,args
ps kstart_time -ef
--lines n
Set screen height.
n Numeric output for WCHAN and USER (including all types of
UID and GID).
--no-headers
Print no header line at all. --no-heading is an alias for
this option.
O order
Sorting order (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).
For sorting, obsolete BSD O option syntax is
O[+|-]k1[,[+|-]k2[,...]]. It orders the processes listing
according to the multilevel sort specified by the sequence
of one-letter short keys k1,k2, ... described in the
OBSOLETE SORT KEYS section below. The "+" is currently
optional, merely re-iterating the default direction on a
key, but may help to distinguish an O sort from an O
format. The "-" reverses direction only on the key it
precedes.
--rows n
Set screen height.
S Sum up some information, such as CPU usage, from dead
child processes into their parent. This is useful for
examining a system where a parent process repeatedly forks
off short-lived children to do work.
--sort spec
Specify sorting order. Sorting syntax is
[+|-]key[,[+|-]key[,...]]. Choose a multi-letter key from
the STANDARD FORMAT SPECIFIERS section. The "+" is
optional since default direction is increasing numerical
or lexicographic order. Identical to k. For example: ps
jax --sort=uid,-ppid,+pid
w Wide output. Use this option twice for unlimited width.
-w Wide output. Use this option twice for unlimited width.
--width n
Set screen width.
