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

SYNOPSIS
     ipcrm [ options ]

DESCRIPTION
     ipcrm will remove one or more specified messages, semaphore 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.

     -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).
