     NAME
          pstat - print system facts

     SYNOPSIS
          pstat [ -aixptuf ] [ suboptions ] [ file ]

     DESCRIPTION
          Pstat interprets the contents of certain system tables.  If
          file is given, the tables are sought there, otherwise in
          /dev/mem. The required namelist is taken from /unix. Options
          are

          -a    Under -p, describe all process slots rather than just
                active ones.

          -i    Print the inode table with the these headings:

          LOC   The core location of this table entry.

                W    waiting for open to complete

                S    has special (output) start routine

          PGRP  Process group for which this is controlling terminal.

          -u    print information about a user process; the next argu-
                ment is its address as given by ps(1). The process
                must be in main memory, or the file used can be a core
                image and the address 0.

          -f    Print the open file table with these headings:

          LOC   The core location of this table entry.
          FLG   Miscellaneous state variables encoded thus:
                R    open for reading
