NAME
     ps - process status

SYNOPSIS
     ps [ aklx ] [ namelist ]

DESCRIPTION
     Ps prints certain indicia about active processes.  The a
     flag asks for information about all processes with typewrit-
     ers (ordinarily only one's own processes are displayed); x
     asks even about processes with no typewriter; l asks for a
     long listing.  Ordinarily only the typewriter number (if not
     one's own), the process number, and an approximation to the
     command line are given.  If the k flag is specified, the
     file /usr/sys/core is used in place of /dev/mem.  This is
     used for postmortem system debugging.  If a second argument
     is given, it is taken to be the file containing the system's
     namelist.

     The long listing is columnar and contains

          The name of the process's control typewriter.

          Flags associated with the process.  01: in core; 02:
          system process; 04: locked in code (e.g. for physical
          I/O); 10: being swapped; 20: being traced by another
          process.

          The state of the process.  0: nonexistent; S: sleeping;
          W: waiting; R: running; Z: terminated; T: stopped.

          The user ID of the process owner.

          The process ID of the process; as in certain cults it
          is possible to kill a process if you know its true
          name.

          The priority of the process; high numbers mean low pri-
          ority.

          The size in blocks of the core image of the process.

          The event for which the process is waiting or sleeping;
          if blank, the process is running.

          The command and its arguments.

     Ps makes an educated guess as to the file name and arguments
     given when the process was created by examining core memory
     or the swap area.  The method is inherently somewhat unreli-
     able and in any event a process is entitled to destroy this
     information, so the names cannot be counted on too much.
