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

   Options
       The identifiers are specified by the following options:

	      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.

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

	      Remove the semaphore identifier
			     semid from the system and destroy the set of sem‐
			     aphores and data structure associated with it.

	      Remove the shared memory identifier, created with key
			     shmkey,  from the system.	The shared memory seg‐
			     ment and data structure associated	 with  it  are
			     destroyed after the last detach.

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

	      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  (see
