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

       SYNOPSIS
             ipcrm [options]

       DESCRIPTION
             ipcrm removes one or more messages, semaphores, or shared
             memory identifiers.  The identifiers are specified by the
             following options:

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

             -m shmid    Remove 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    Remove the semaphore identifier semid from the
                         system and destroy the set of semaphores and data
                         structure associated with it.

             -Q msgkey   Remove the message queue identifier, created with
                         key msgkey, from the system and destroy 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   Remove the semaphore identifier, created with key
                         semkey, from the system and destroy 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).  Use the ipcs command to find the
             identifiers and keys.
