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.
