NAME

     ipcrm - remove the specified message queues, semaphore sets, and shared
     memory segments


SYNOPSIS

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


DESCRIPTION

     ipcrm removes the specified message queues, semaphores and shared memory
     segments.  These System V IPC objects can be specified by their creation
     id or any associated key.

     The following options are used to specify which IPC objects will be
     removed.  Any number and combination of these options can be used:

     -q msqid
             Remove the message queue associated with the id msqid from the
             system.

     -m shmid
             Mark the shared memory segment associated with id shmid for
             removal.  This marked segment will be destroyed after the last
             detach.

     -s semid
             Removes the semaphore set associated with id semid from the sys-
             tem.

     -Q msgkey
             Remove the message queue associated with key msgkey from the sys-
             tem.

     -M shmkey
             Mark the shared memory segment associated with key shmkey for
             removal.  This marked segment will be destroyed after the last
             detach.

     -S semkey
             Remove the semaphore set associated with key semkey from the sys-
             tem.

     The identifiers and keys associated with these System V IPC objects can
     be determined by using ipcs(1).
