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 iden‐
       tifiers.

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 sys‐
		    tem. The shared memory segment and data structure  associ‐
		    ated 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  associ‐
		    ated with it.

       -s semid	    Removes the semaphore identifier semid from the system and
		    destroys the set of semaphores and data structure  associ‐
		    ated 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 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.
