DESCRIPTION    [Toc]    [Back]

     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 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).
