DESCRIPTION
      ipcrm removes one or more messages,  semaphores,  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 struc-
            ture 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
            Removes the shared memory identifier, created with key
            shmkey, from the system.
             The shared memory segment and data structure  associ-
            ated 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 sem-
            key, from the system and destroy 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.
