     NAME
          ipcrm - remove message, semaphore, or shared memory id

     SYNOPSIS
          ipcrm [ options ]

     DESCRIPTION
          The ipcrm command will remove one or more specified
          messages, semaphores or shared memory identifiers.  The
          identifiers are specified by the following 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.  Msgkey is a decimal value.

          -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.
                      Shmkey is a decimal value.

          -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.  Semkey is a decimal value.

          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).

     CAVEAT
          The ipcs(1) command returns hex values.  If you use it to
          return values for use by ipcrm(1) with the S, Q, or M
          switches, you must convert the values to decimal before
          giving them to ipcrm.
