ps - display the status of current processes


     /usr/ucb/ps [-aceglnrSuUvwx] [-t term] [num]


     The ps command displays information  about  processes.  Nor-
     mally,  only  those  processes  that  are  running with your
     effective user ID and are attached to a controlling terminal
     (see    termio(7I))  are  shown.  Additional  categories  of
     processes can be added to the display using various options.
     In particular, the -a option allows you to include processes
     that are not owned by you (that do not have your  user  ID),
     and  the  -x  option allows you to include processes without
     controlling terminals. When you specify both -a and -x,  you
     get processes owned by anyone, with or without a controlling
     terminal. The -r option  restricts  the  list  of  processes
     printed to running and runnable processes.

     ps displays in tabular form the process ID, under  PID;  the
     controlling  terminal  (if any), under TT; the cpu time used
     by the process so far, including both user and system  time,
     under  TIME; the state of the process, under S; and finally,
     an indication of the COMMAND that is running.

     The state is given by a single letter from the following:

     O     Process is running on a processor.

     S     Sleeping. Process is waiting for an event to complete.

     R     Runnable. Process is on run queue.

     Z     Zombie state. Process terminated and parent not  wait-

     T     Traced. Process stopped by a signal because parent  is
           tracing it.


     The following options must all be combined to form the first

     -a    Includes information about processes owned by others.

     -c    Displays the command  name  rather  than  the  command

     -e    Displays the environment as well as the  arguments  to
           the command.

     -g    Displays all processes. Without this option,  ps  only
           prints  interesting processes. Processes are deemed to
           be uninteresting if they are  process  group  leaders.
           This  normally  eliminates  top-level  command  inter-
           preters and processes waiting for users  to  login  on
           free terminals.

     -l    Displays a long listing, with fields F, PPID, CP, PRI,
           NI, SZ, RSS, and WCHAN as described below.

     -n    Produces numerical output for some fields. In  a  user
           listing, the USER field is replaced by a UID field.

     -r    Restricts output to running and runnable processes.

     -S    Displays accumulated CPU time used by this process and
           all of its reaped  children.

     -t term
           Lists only process data associated with the  terminal,
           term.  Terminal identifiers may be specified in one of
           two forms:   the  device's  file  name  (for  example,
           tty04  or  term/14  )  or,  if  the device's file name
           starts with  tty, just the digit identifier (for exam-
           ple, 04).

     -u    Displays user-oriented output.  This  includes  fields
           USER,  %CPU,  %MEM,  SZ,  RSS,  and START as described

     -U    Obsolete. This option no longer  has  any  effect.  It
           causes  ps  to exit without printing the process list-

     -v    Displays a version of the  output  containing  virtual
           memory.  This  includes  fields  SIZE, %CPU, %MEM, and
           RSS, described below.

     -w    Uses a wide output format  (132  columns  rather  than
           80).  If  the option letter is repeated, that is, -ww,
           uses arbitrarily wide output. This information is used
           to  decide  how  much of long commands to print. Note:
           The wide  output  option  can  be  viewed  only  by  a
           superuser or the user who owns the process.

     -x    Includes processes with no controlling terminal.

     num   A process number may be given, in which case the  out-
           put is restricted to that process. This option must be
           supplied last.


     Fields that are not common to all output formats:

     USER  Name of the owner of the process.

     %CPU  CPU use of the process. This  is  a  decaying  average
           over up to a minute of previous (real) time.

     NI    Process scheduling increment (see getpriority(3C)  and

     SIZE  The total size  of  the  process  in  virtual  memory,
           including  all  mapped  files and devices, in kilobyte

     SZ    Same as SIZE.

     RSS   Real memory (resident set) size  of  the  process,  in
           kilobyte units.

     UID   Numerical user-ID of process owner.

     PPID  Numerical ID of parent of process.

     CP    Short-term CPU utilization factor  (used  in  schedul-

     PRI   The priority of the process (higher numbers mean lower

     START The starting time of  the  process,  given  in  hours,
           minutes,  and  seconds.  A  process begun more than 24
           hours before the ps inquiry is executed  is  given  in
           months and days.

     WCHAN The address of an  event  for  which  the  process  is
           sleeping (if blank, the process is running).

     %MEM  The ratio of the process's resident set  size  to  the
           physical memory on the machine, expressed as a percen-

     F     Flags (hexadecimal and additive) associated  with  the
           process. These flags are available for historical pur-
           poses; no meaning  should  be  currently  ascribed  to

     A process that has exited and has a parent, but has not  yet
     been  waited  for by the parent, is marked <defunct>; other-
     wise, ps tries to determine the command name  and  arguments
     given  when  the  process  was created by examining the user

     Things can change while ps is running. The picture ps  gives
     is  only  a  close  approximation to the current state. Some
     data printed for defunct processes is irrelevant.
