     PSTAT(C)                 XENIX System V                  PSTAT(C)



     Name
          pstat - Reports system information.

     Syntax
          pstat [ -aixpf ] [ -u ubase ] [ -c corefile ]
          [ -n namelist ] [ file ]

     Description
          pstat interprets the contents of certain system tables.
          pstat searches for these tables in /dev/mem and /dev/kmem.
          With the file given, the tables are sought in the specified
          file rather than /dev/mem. Similarly, the -c option allows
          one to specify a corefile rather than /dev/kmem for the
          search.  The required namelist is taken from /xenix. Options
          are:

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

          -i    Print the inode table with these headings:
                LOC     The core location of this table entry.
