 NAME
      ipcrm - remove a message queue, semaphore set, or shared memory
      identifier

 SYNOPSIS
      ipcrm [option]...

 DESCRIPTION
      The ipcrm command removes one or more specified message queue,
      semaphore set, or shared memory identifiers.

    Options
      The identifiers are specified by the following options:

	   -m shmid	  Remove 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	  Remove the message queue identifier msqid from the
			  system and destroy the message queue and data
			  structure associated with it.

	   -s semid	  Remove the semaphore identifier semid from the
			  system and destroy the set of semaphores and data
			  structure associated with it.

	   -M shmkey	  Remove 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	  Remove the message queue identifier, created with
			  key msgkey, from the system and destroy the
			  message queue and data structure associated with
			  it.

	   -S semkey	  Remove the semaphore identifier, created with key
			  semkey, from the system and destroy the set of
			  semaphores and data structure associated with it.

      The details of the removals are described in msgctl(2), shmctl(2), and
      semctl(2).  The identifiers and keys can be found by using ipcs (see
      ipcs(1)).
