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 structure
		    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  struc-
		    ture associated with it.

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