SUMMARY
-------
Display process status information
::
ps [-k|-u|-G][-s|-n][-p|-c|-t|-l|-a|-g|-r] [pid | taskp | command] ...``
DESCRIPTION
-----------
This command displays process status for selected, or all, processes
in the system. If no arguments are entered, the process data is
is displayed for all processes. Specific processes may be selected
by using the following identifier formats:
``pid`` -- a process PID
``taskp`` -- a hexadecimal ``struct task_struct`` pointer
``command`` -- a command name
If a command name is made up of letters that are all numerical values,
precede the name string with a ". If the command string is
enclosed within "'" characters, then the encompassed string must be a
POSIX extended regular expression that will be used to match task names.
The process list may be further restricted by the following options:
``-k`` restrict the output to only kernel threads.
``-u`` restrict the output to only user tasks.
``-G`` display only the thread group leader in a thread group.
The process identifier types may be mixed. For each task, the following
items are displayed:
1. the process PID.
2. the parent process PID.
3. the CPU number that the task ran on last.
4. the task_struct address or the kernel stack pointer of the process.
(see -s option below)
5. the task state (RU, IN, UN, ZO, ST, TR, DE, SW).
6. the percentage of physical memory being used by this task.
7. the virtual address size of this task in kilobytes.
8. the resident set size of this task in kilobytes.
9. the command name.
The default output shows the task_struct address of each process under a
column titled "``TASK``". This can be changed to show the kernel stack
pointer under a column titled "``KSTACKP``".
``-s`` replace the ``TASK`` column with the ``KSTACKP`` column.
On SMP machines, the active task on each CPU will be highlighted by an
angle bracket (">") preceding its information.
Alternatively, information regarding parent-child relationships,
per-task time usage data, argument/environment data, thread groups,
or resource limits may be displayed:
``-p`` display the parental hierarchy of selected, or all, tasks.
``-c`` display the children of selected, or all, tasks.
``-t`` display the task run time, start time, and cumulative user and system times.
``-l`` display the task last_run or timestamp value, whichever applies, of selected, or all, tasks; the list is sorted with the most recently-run task (largest last_run/timestamp) shown first, followed by the task's current state.
``-a`` display the command line arguments and environment strings of selected, or all, user-mode tasks.
``-g`` display tasks by thread group, of selected, or all, tasks.
``-r`` display resource limits (rlimits) of selected, or all, tasks.
``-n`` display gdb thread number
