NAME
ps  report a snapshot of the current processes.SYNOPSIS
ps [options]
DESCRIPTION
ps displays information about a selection of the active processes. If you want a repetitive update of the selection and the displayed information, use top(1) instead. This version of ps accepts several kinds of options: 1
 UNIX options, which may be grouped and must be preceded by a dash.
 2
 BSD options, which may be grouped and must not be used with a dash.
 3
 GNU long options, which are preceded by two dashes.
Options of different types may be freely mixed, but conflicts can appear. There are some synonymous options, which are functionally identical, due to the many standards and ps implementations that this ps is compatible with. Note that "ps aux" is distinct from "ps aux". The POSIX and UNIX standards require that "ps aux" print all processes owned by a user named "x", as well as printing all processes that would be selected by the a option. If the user named "x" does not exist, this ps may interpret the command as "ps aux" instead and print a warning. This behavior is intended to aid in transitioning old scripts and habits. It is fragile, subject to change, and thus should not be relied upon. By default, ps selects all processes with the same effective user ID (euid=EUID) as the current user and associated with the same terminal as the invoker. It displays the process ID (pid=PID), the terminal associated with the process (tname=TTY), the cumulated CPU time in [dd]hh:mm:ss format (time=TIME), and the executable name (ucmd=CMD). Output is unsorted by default. The use of BSDstyle options will add process state (stat=STAT) to the default display and show the command args (args=COMMAND) instead of the executable name. You can override this with the PS_FORMAT environment variable. The use of BSDstyle options will also change the process selection to include processes on other terminals (TTYs) that are owned by you; alternately, this may be described as setting the selection to be the set of all processes filtered to exclude processes owned by other users or not on a terminal. These effects are not considered when options are described as being "identical" below, so M will be considered identical to Z and so on. Except as described below, process selection options are additive. The default selection is discarded, and then the selected processes are added to the set of processes to be displayed. A process will thus be shown if it meets any of the given selection criteria.

userdefined format.
format is a single argument in the form of a blankseparated or commaseparated 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=WIDEWCHANCOLUMN 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.

Sorting order. (overloaded)
The BSD O option can act like O (userdefined 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 oneletter short keys k1, k2, ... described in the OBSOLETE SORT KEYS section below. The "+" is currently optional, merely reiterating 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.

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 noheaders to enable printing headers each page or disable headers entirely, respectively.

NOTES
This ps works by reading the virtual files in /proc. This ps does not need to be setuid kmem or have any privileges to run. Do not give this ps any special permissions.This ps needs access to namelist data for proper WCHAN display. For kernels prior to 2.6, the System.map file must be installed.
CPU usage is currently expressed as the percentage of time spent running during the entire lifetime of a process. This is not ideal, and it does not conform to the standards that ps otherwise conforms to. CPU usage is unlikely to add up to exactly 100%.
The SIZE and RSS fields don't count some parts of a process including the page tables, kernel stack, struct thread_info, and struct task_struct. This is usually at least 20 KiB of memory that is always resident. SIZE is the virtual size of the process (code+data+stack).
Processes marked <defunct> are dead processes (socalled "zombies") that remain because their parent has not destroyed them properly. These processes will be destroyed by init(8) if the parent process exits.
PROCESS FLAGS
The sum of these values is displayed in the "F" column, which is provided by the flags output specifier. 1
 forked but didn't exec
 4
 used superuser privileges
PROCESS STATE CODES
Here are the different values that the s, stat and state output specifiers (header "STAT" or "S") will display to describe the state of a process. D
 Uninterruptible sleep (usually IO)
 R
 Running or runnable (on run queue)
 S
 Interruptible sleep (waiting for an event to complete)
 T
 Stopped, either by a job control signal or because it is being traced.
 W
 paging (not valid since the 2.6.xx kernel)
 X
 dead (should never be seen)
 Z
 Defunct ("zombie") process, terminated but not reaped by its parent.
For BSD formats and when the stat keyword is used, additional characters may be displayed:
 <
 highpriority (not nice to other users)
 N
 lowpriority (nice to other users)
 L
 has pages locked into memory (for realtime and custom IO)
 s
 is a session leader
 l
 is multithreaded (using CLONE_THREAD, like NPTL pthreads do)
 +
 is in the foreground process group
OBSOLETE SORT KEYS
These keys are used by the BSD O option (when it is used for sorting). The GNU sort option doesn't use these keys, but the specifiers described below in the STANDARD FORMAT SPECIFIERS section. Note that the values used in sorting are the internal values ps uses and not the "cooked" values used in some of the output format fields (e.g. sorting on tty will sort into device number, not according to the terminal name displayed). Pipe ps output into the sort(1) command if you want to sort the cooked values.

AIX FORMAT DESCRIPTORS
This ps supports AIX format descriptors, which work somewhat like the formatting codes of printf(1) and printf(3). For example, the normal default output can be produced with this: ps eo "%p %y %x %c". The NORMAL codes are described in the next section.CODE  NORMAL  HEADER 
%C  pcpu  %CPU 
%G  group  GROUP 
%P  ppid  PPID 
%U  user  USER 
%a  args  COMMAND 
%c  comm  COMMAND

%r  pgid  PGID 
%t  etime  ELAPSED 
%u  ruser  RUSER

STANDARD FORMAT SPECIFIERS
Here are the different keywords that may be used to control the output format (e.g. with option o) or to sort the selected processes with the GNUstyle sort option.For example: ps eo pid,user,args sort user
This version of ps tries to recognize most of the keywords used in other implementations of ps.
The following userdefined format specifiers may contain spaces: args, cmd, comm, command, fname, ucmd, ucomm, lstart, bsdstart, start.
Some keywords may not be available for sorting.
CODE  HEADER  DESCRIPTION 
%cpu  %CPU 
cpu utilization of the process in "##.#" format. Currently, it is the CPU time
used divided by the time the process has been running (cputime/realtime
ratio), expressed as a percentage. It will not add up to 100% unless you
are lucky. (alias pcpu).

%mem  %MEM 
ratio of the process's resident set size to the physical memory on
the machine, expressed as a percentage. (alias pmem).

args  COMMAND 
command with all its arguments as a string. Modifications to the arguments
may be shown. The output in this column may contain spaces.
A process marked <defunct> is partly dead, waiting
to be fully destroyed by its parent. Sometimes the process args
will be unavailable; when this happens, ps will instead
print the executable name in brackets.
(alias cmd, command). See also the comm format
keyword, the f option, and the c option.
When specified last, this column will extend to the edge of the display. If ps can not determine display width, as when output is redirected (piped) into a file or another command, the output width is undefined. (it may be 80, unlimited, determined by the TERM variable, and so on) The COLUMNS environment variable or cols option may be used to exactly determine the width in this case. The w or w option may be also be used to adjust width. 
blocked  BLOCKED 
mask of the blocked signals, see signal(7).
According to the width of the field,
a 32bit or 64bit mask in hexadecimal format is displayed.
(alias sig_block, sigmask).

bsdstart  START 
time the command started. If the process was started less
than 24 hours ago, the output format is " HH:MM",
else it is "mmm dd"
(where mmm is the three letters of the month).

accumulated cpu time, user + system. The display format is usually
"MMM:SS", but can be shifted to the right if the process used more than 999
minutes of cpu time.

c  C 
processor utilization. Currently, this is the integer value of
the percent usage over the lifetime of the process. (see %cpu).

keyword, the f option, and the c option.
When specified last, this column will extend to the edge of the display. If ps can not determine display width, as when output is redirected (piped) into a file or another command, the output width is undefined. (it may be 80, unlimited, determined by the TERM variable, and so on) The COLUMNS environment variable or cols option may be used to exactly determine the width in this case.

AUTHOR
ps was originally written by Branko Lankester <lankeste@fwi.uva.nl>. Michael K. Johnson <johnsonm@redhat.com> rewrote it significantly to use the proc filesystem, changing a few things in the process. Michael Shields <mjshield@nyx.cs.du.edu> added the pidlist feature. Charles Blake <cblake@bbn.com> added multilevel sorting, the direntstyle library, the device nametonumber mmaped database, the approximate binary search directly on System.map, and many code and documentation cleanups. David MossbergerTang wrote the generic BFD support for psupdate. Albert Cahalan <albert@users.sf.net> rewrote ps for full Unix98 and BSD support, along with some ugly hacks for obsolete and foreign syntax.Please send bug reports to <procpsfeedback@lists.sf.net>.
