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.
Options
The available options are as follows:
-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.
FLAGS Miscellaneous state variables encoded thus:
L Locked
U Update time filesystem(F) 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 (executable image) 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(S).
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 Prints the text (executable code segment) table with
these headings (-286 only):
LOC The core location of this table entry.
FLAGS Miscellaneous state variables encoded thus:
T ptrace(S) 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
BSIZE bytes.
CADDR Core address, measured in units of memory
management resolution.

SIZE Size of text segment, measured in units of
memory management resolution.
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
Prints 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, ORed together:
01 Loaded
02 The scheduler process
04 Locked
010 Swapped out
020 Traced
040 Used in tracing
0100 Locked in by lock(S).
PRI Scheduling priority, see nice(S).
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(S).
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.
ADDR1, ADDR2
If in core, the physical page frame numbers of the
u-area of the process. These numbers can be
translated into the addresses of the u-area, which
is split and stored in two pages. If swapped out,
the position in the swap area is measured in
multiples of BSIZE 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 (286 only).
INODP Pointer to location of shared inode (386 only).
CLKT Countdown for alarm(S) measured in seconds.
-t

PSTAT(C) XENIX System V PSTAT(C)
Print table for terminals with these headings:
RAW Number of characters in raw input queue.
CAN Number of characters in canonicalized input queue.
OUT Number of characters in output queue.
IMODE Corresponds to c_iflag field in termio structure,
see tty(M).
OMODE Corresponds to c_oflag field in termio structure,
see tty(M).
CMODE Corresponds to c_cflag field in termio structure,
see tty(M).
LMODE Corresponds to c_lflag field in termio structure,
see tty(M).
ADDR Physical device address.
DEL Number of delimiters (newlines) in canonicalized
input queue.
COL Calculated column position of terminal.
STATE Miscellaneous state variables:
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 controlling terminal.
-f
Print the open file table with these headings:
LOC The core location of this table entry.
FLG Miscellaneous state variables:
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.
OFFS The file offset, see lseek(S).
-u ubase
Print information about a user process. ubase is the
hexadecimal location of the process in main memory. The
address can be obtained by using the long listing ( -l
option) of the ps(C) command.
-c corefile
Use the file corefile in place of /dev/kmem.
-n namelist
Use the file namelist as an alternate namelist in place of
/xenix.
file
Source or tables as an alternate to /dev/mem.

/xenix Namelist
