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
		       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	struc‐
		       ture 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 structure associated with it.

       -S semkey       Removes the  semaphore  identifier,  created  with  key
		       semkey,	from  the system and destroys the set of sema‐
		       phores 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.
