SYNOPSIS
ipcrm [-M shmkey] [-m shmid] [-Q msgkey] [-q msqid] [-S semkey]

DESCRIPTION
ipcrm 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:
-M shmkey
Mark the shared memory segment associated with key shmkey for
removal. This marked segment will be destroyed after the last
detach.
-m shmid
Mark the shared memory segment associated with ID shmid for
removal. This marked segment will be destroyed after the last
detach.
-Q msgkey
Remove the message queue associated with key msgkey from the sys-
tem.
-q msqid
Remove the message queue associated with the ID msqid from the
system.
-S semkey
Remove the semaphore set associated with key semkey from the sys-
tem.
-s semid
Removes the semaphore set associated with ID semid from the sys-
tem.
If the id or key argument is ``all'' then all entries of the appropriate
type are removed.
The identifiers and keys associated with these System V IPC objects can
be determined by using ipcs(1).
