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:
	     L	    locked
	     U	    update time filsys(5)) must be corrected
	     A	    access time must be corrected
	     M	    file system is mounted here
	     W	    wanted by another process (L flag is on)
	     T	    contains a text file
	     C	    changed time must be corrected
       CNT   Number of open file table entries for this inode.
       DEV   Major  and	 minor	device	number	of file system in
	     which this inode resides.
       INO   I-number within the device.
       MODE  Mode bits, see chmod(2).
       NLK   Number of links to this inode.
       UID   User ID of owner.
       SIZ/DEV
	     Number of bytes in an ordinary file,  or  major  and
	     minor device of 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.

PSTAT(1M)						PSTAT(1M)

       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 controlling 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 han-
	     dled) with these headings:

       RAW   Number of characters in raw input queue.
       CAN   Number of characters in canonicalized input queue.
       OUT   Number of characters in putput queue.

	     input queue.
       COL   Calculated column position of terminal.
       STATE Miscellaneous state variables encoded thus:

	     X	    open for exclusive use
	     H	    hangup on close
       PGRP  Process  group  for which this is controlling termi-
	     nal.

       -u    print information about a	user  process;	the  next
	     argument is its address as given by ps(1).	 The pro-
	     cess 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.
