PSTAT(8)                  BSD System Manager's Manual                 PSTAT(8)

NAME
     pstat - print system tables

SYNOPSIS
     pstat [-i | -t]

DESCRIPTION
     Pstat prints the contents of various system tables.

     The options are as follows:

     -i       Print the contents of the vnode table in the following format:

              ADDR     The kernel address of this table entry.
              VFLAG    The vnode flags as follows:
                       R        Root of its filesystem.
                       T        Vnode is pure text prototype.
                       I        Vnode being used by kernel.
                       L        Vnode is locked to change underlying type.
                       W        Process is waiting for vnode.
                       B        Waiting for output to complete.
                       A        Vnode has an alias.
              USE      Reference count of users.
              HOLD     Reference count of writers.
              FILEID   Inode number (UFS) or Fileid (NFS).
              IFLAG    flags for UFS filesystem:
                       L        Inode is locked.
                       W        Some process waiting on lock.
                       R        Inode is being renamed.
                       U        File has been modified.
                       A        Inode access time to be updated.
                       C        Inode has been changed.
                       M        Inode has been modified.
                       S        File has shared lock.
                       X        File has exclusive lock.
                       w        Someone waiting on file lock.
              NFLAG    flags for NFS filesystem:
                       L        Lock the node for other local accesses.
                       W        Want above lock.
                       M        Might have a modified buffer in bio.
                       E        Flag write errors so close will know.
              XFLAG    flags for ISO9660 filesystem:
                       L        Inode is locked.
                       W        Some process is waiting on lock.
              MODE     File permissions.
              UID      User ID of owner.
              SIZ/DEV  Size or Device name.

              Each filesystem block is preceded by it's mount information,
              for example: *** MOUNT ufs /dev/wd0a on / (local)

     -t       Print the contents of the tty table in the following format:

              LINE     Device name (if known) or unit number.
              RAW      Number of characters in raw input queue.
              CAN      Number of characters in canonicalized input queue.
              OUT      Number of characters in output queue.
              ADDR     Physical device address (currently unused).
              COL      Calculated column position of terminal.
              STATE    Miscellaneous state variables as follows:
                       T        Delay timeout in progress.
                       W        Waiting for open to complete.
                       O        Device is open.
                       F        Outq has been flushed during DMA.

                       C        Software copy of carrier-present.
                       B        Busy, output in progress.
                       A        Async mode awaiting output.
                       X        Exclusive-use flag against open.
                       S        Output stopped by ctl-s.
                       H        Hang up on last close.
              SESS     Address of kernel session structure.
              PGRP     Process group ID.
              DISC     Line discipline.

              LINE is resolved where possible to the device name, otherwise
              is it simply a unique identifier for the unit.

FILES
     /var/run/dev.db  device name database
