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).
