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

          SYNOPSIS
               ipcrm [ options ]

          DESCRIPTION
               The ipcrm command will remove one or more specified mes-
               sages, semaphore or shared memory identifiers.  The identif-
               iers 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.

               -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).
