NAME

       ipcrm - remove a message queue, semaphore set, or shared memory ID

SYNOPSIS

       ipcrm [-z zone] [-m shmid] [-q msqid] [-s semid] [-M shmkey] [-Q msgkey] [-S semkey]

DESCRIPTION

       ipcrm removes one or more messages, semaphores, or shared memory identifiers.

OPTIONS

       The following option is supported:

       -z zone	       Keys  specified by other options refer to facilities in the specified zone (see zones(5)). The default is the zone in which
		       the command is executing. This option is only useful when the command is executed in the global zone.

       The identifiers are specified by the following options:

       -m shmid        Removes the shared memory identifier shmid from the system. The shared memory segment and data structure associated with it
		       are destroyed after the last detach.

       -q msqid        Removes	the  message  queue  identifier msqid from the system and destroys the message queue and data structure associated
		       with it.

       -s semid        Removes the semaphore identifier semid from the system and destroys the set of semaphores  and  data  structure	associated
		       with it.

       -M shmkey       Removes	the  shared memory identifier, created with key shmkey, from the system. The shared memory segment and data struc-
		       ture associated with it are destroyed after the last detach.

       -Q msgkey       Removes the message queue identifier, created with key msgkey, from the system and destroys  the  message  queue  and  data
		       structure associated with it.

       -S semkey       Removes	the  semaphore	identifier,  created  with key semkey, from the system and destroys the set of semaphores and data
		       structure associated with it.

       The details of the removes are described in msgctl(2), shmctl(2), and semctl(2).  Use the ipcs command to find the identifiers and keys.

NAME

     ipcrm -- remove the specified message queues, semaphore sets, and shared segments

SYNOPSIS

     ipcrm [-W] [-v] [-q msqid] [-m shmid] [-s semid] [-Q msgkey] [-M shmkey] [-S semkey] ...

DESCRIPTION

     The ipcrm utility removes the specified message queues, semaphores and shared memory segments.  These System V IPC objects can be specified
     by their creation ID or any associated key.

     The following options are generic:

     -v      If specified once with -W or with -1 for an object, it will show all removed objects.  If specified twice with -W or with -1 for an
	     objects, it will show all removed objects and all failed removals.

     -W      Try to wipe all specified message queues, semaphores and shared memory segments.

     -y      Use the kvm(3) interface instead of the sysctl(3) interface to extract the required information.  If ipcrm is to operate on the run-
	     ning system, using kvm(3) will require read privileges to /dev/kmem.

     The following options are used to specify which IPC objects will be removed.  Any number and combination of these options can be used:

     -q msqid
	     Remove the message queue associated with the ID msqid from the system.

     -m shmid
	     Mark the shared memory segment associated with ID shmid for removal.  This marked segment will be destroyed after the last detach.

     -s semid
	     Remove the semaphore set associated with ID semid from the system.

     -Q msgkey
	     Remove the message queue associated with key msgkey from the system.

     -M shmkey
	     Mark the shared memory segment associated with key shmkey for removal.  This marked segment will be destroyed after the last detach.

     -S semkey
	     Remove the semaphore set associated with key semkey from the system.

     The identifiers and keys associated with these System V IPC objects can be determined by using ipcs(1).  If the identifier or the key is -1,
     it will remove all these objects.

HISTORY

     The wiping of all System V IPC objects was first implemented in FreeBSD 6.4 and 7.1.

AUTHORS

     The original author was Adam Glass.  The wiping of all System V IPC objects was thought up by Callum Gibson and extended and implemented by
     Edwin Groothuis.
