NAME

    pstat - print system facts

SYNOPSIS

    pstat [ -aixptuf ] [ suboptions ] [ file ]

DESCRIPTION

    _P_s_t_a_t interprets the contents of certain system tables.  If
    _f_i_l_e is given, the tables are sought there, otherwise in
    /_d_e_v/_k_m_e_m. The required namelist is taken from /_u_n_i_x.
    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 _f_i_l_s_y_s(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 _c_h_m_o_d(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    _p_t_r_a_c_e(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 _l_o_c_k(2)
          0200 partially swapped.
    PRI   Scheduling priority, see _n_i_c_e(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 _n_i_c_e(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 _a_l_a_r_m(2) measured in seconds.

    -t    Print table for terminals (only DH11 and DL11 handled)
          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.
    MODE  See _t_t_y(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 argu-
          ment is its address as given by _p_s(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.
    OFFS  The file offset, see _l_s_e_e_k(2).

FILES

    /unix      namelist
    /dev/kmem  default source of tables
