PSTAT(1M)                                                            PSTAT(1M)



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.
       FLAGS Miscellaneous state variables encoded thus:

             U      update time filsys(5)) must be corrected

             special file.

       -x    Print the text table with these headings:

       LOC   The core location of this table entry.
       FLAGS Miscellaneous state variables encoded thus:
             T      ptrace(2) in effect
             W      text not yet written on swap device
             L      loading in progress
             K      locked
             w      wanted (L flag is on)

       DADDR Disk address in swap, measured in multiples of 512 bytes.

       CADDR Core address, measured in multiples of 64 bytes.

       SIZE  Size of text segment, measured in multiples of 64 bytes.

       IPTR  Core location of corresponding inode.

       CNT   Number of processes using this text segment.

       CCNT  Number of processes in core using this text segment.

       -p    Print process table for active processes with these headings:

       LOC   The core location of this table entry.
       S     Run state encoded thus:
             0      no process
             1      waiting for some event
             3      runnable
             4      being created
             5      being terminated
             6      stopped under trace
       F     Miscellaneous state variables, or-ed together:
             01     loaded
             02     the scheduler process
             04     locked
             010    swapped out
             020    traced
             040    used in tracing
             0100   locked in by lock(2).
       PRI   Scheduling priority, see nice(2).
       SIGNAL
             Signals received (signals 1-16 coded in bits 0-15),
       UID   Real user ID.
       TIM   Time resident in seconds; times over 127 coded as 127.
       CPU   Weighted integral of CPU time, for scheduler.
       NI    Nice level, see nice(2).
       PGRP  Process number of root of process group (the opener of  the  con-
             trolling terminal).
       PID   The process ID number.
       PPID  The process ID of parent process.
       ADDR  If  in  core, the physical address of the `u-area' of the process
             measured in multiples of 64 bytes.  If swapped out, the  position
             in the swap area measured in multiples of 512 bytes.
       SIZE  Size of process image in multiples of 64 bytes.
       WCHAN Wait channel number of a waiting process.
       LINK  Link pointer in list of runnable processes.
       TEXTP If text is pure, pointer to location of text table entry.
       CLKT  Countdown for alarm(2) measured in seconds.

       -t    Print table for terminals (only DH11 and DL11 handled) with these
             headings:

       OUT   Number of characters in putput queue.
       MODE  See tty(4).
       ADDR  Physical device address.
       DEL   Number of delimiters (newlines) in canonicalized input queue.
       COL   Calculated column position of terminal.
       STATE Miscellaneous state variables encoded thus:
             W      waiting for open to complete
             O      open
             S      has special (output) start routine
             C      carrier is on
             B      busy doing output
             A      process is awaiting output
             X      open for exclusive use
             H      hangup on close
       PGRP  Process group for which this is controlling terminal.

       -u    print information about a user process; the next argument 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
             W      open for writing
             P      pipe
       CNT   Number of processes that know this open file.
       INO   The location of the inode table entry for this file.
