- Modified Sat Oct 9 10:55:28 1993 for 0.99.13
-
- Patches from Mike Jagdis (jaggy@purplet.demon.co.uk) applied Wed Feb
- 8 12:12:21 1995 by faith@cs.unc.edu to print numeric uids if no
- passwd file entry.
-
- Patch from arnolds@ifns.de (Heinz-Ado Arnolds) applied Mon Jul 1
- 19:30:41 1996 by janl@math.uio.no to add code missing in case PID:
- clauses.
-
- Patched to display the key field -- hy@picksys.com 12/18/96
-
- 1999-02-22 Arkadiusz Miç§iewicz <misiek@pld.ORG.PL>
- - added Native Language Support

+.Sh NAME
+.Nm ipcs
+.Nd report System V interprocess communication facilities status
+.Sh SYNOPSIS
+.Nm
+.Op Fl abcmopqstMQST
+.Sh DESCRIPTION
+The
+.Nm
+program provides information on System V interprocess communication
+(IPC) facilities on the system.
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl a
+Show the maximum amount of information possible when
+displaying active semaphores, message queues,
+and shared memory segments.
+(This is shorthand for specifying the
+.Fl b ,
+.Fl c ,
+.Fl o ,
+.Fl p ,
+and
+.Fl t
+options.)
+.It Fl b
+Show the maximum allowed sizes for active semaphores, message queues,
+and shared memory segments.
+The
+.Dq maximum allowed size
+is the maximum number of bytes in a message on a message queue,
+the size of a shared memory segment,
+or the number of semaphores in a set of semaphores.
+.It Fl c
+Show the creator's name and group for active semaphores, message queues,
+and shared memory segments.
+.It Fl m
+Display information about active shared memory segments.
+.It Fl o
+Show outstanding usage for active message queues,
+and shared memory segments.
+The
+.Dq outstanding usage
+is the number of messages in a message queue, or the number
+of processes attached to a shared memory segment.
+.It Fl p
+Show the process ID information for active semaphores, message queues,
+and shared memory segments.
+The
+.Dq process ID information
+is the last process to send a message to or receive a message from
+a message queue,
+the process that created a semaphore, or the last process to attach
+or detach a shared memory segment.
+.It Fl q
+Display information about active message queues.
+.It Fl s
+Display information about active semaphores.
+.It Fl t
+Show access times for active semaphores, message queues,
+and shared memory segments.
+The access times is the time
+of the last control operation on an IPC object,
+the last send or receive of a message,
+the last attach or detach of a shared memory segment,
+or the last operation on a semaphore.
+.It Fl M
+Display system information about shared memory.
+.It Fl Q
+Display system information about messages queues.
+.It Fl S
+Display system information about semaphores.
+.It Fl T
+Display system information about shared memory, message queues
+and semaphores.
+(This is shorthand for specifying the
+.Fl M ,
+.Fl Q ,
+and
+.Fl S
+options.)
+.El
+.Pp
+If none of the
+.Fl M ,
+.Fl m ,
+.Fl Q ,
+.Fl q ,
+.Fl S ,
+.Fl s ,
+or
+.Fl T
+options are specified, information about all active IPC facilities is
+listed.
+.Sh RESTRICTIONS
+System data structures may change while
+.Nm
+is running; the output of
+.Nm
+is not guaranteed to be consistent.
+.Sh SEE ALSO
+.Xr ipcrm 1 ,

+.Xr shmget 2

+.Sh BUGS
+This manual page is woefully incomplete, because it does not
+at all attempt to explain the information printed by
+.Nm .
