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 options are as follows: -M shmkey Mark the shared memory segment associated with key shmkey for re- moval. This marked segment will be destroyed after the last de- tach. -m shmid Mark the shared memory segment associated with ID shmid for remo- val. This marked segment will be destroyed after the last detach. -Q msgkey Remove the message queue associated with key msgkey from the sys- tem. -q msqid Remove the message queue associated with the ID msqid from the system. -S semkey Remove the semaphore set associated with key semkey from the sys- tem. -s semid Removes the semaphore set associated with ID semid from the sys- tem. The identifiers and keys associated with these System V IPC objects can be determined by using ipcs(1).
