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

     SYNOPSIS
          ipcrm [-m shmid] [-M shmkey] [-q msqid] [-Q msgkey
          [-s semid] [-S semkey]

     DESCRIPTION
          ipcrm will remove one or more specified message, semaphore
          or shared memory identifiers.  The identifiers are specified
          by the following flag options:

          -q msqid   removes the message queue identifier msqid from
                     the system and destroys the message queue and
                     data structure associated with it.

          -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.

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

          -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.

          -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.

          -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).  The identifiers and keys may be
          found by using ipcs(1).
