This option is only useful when the command is executed in the global zone. The identifiers are specified by the following options: -m shmid Removes the shared memory identifier shmid from the system. The shared memory segment and data structure associated with it are destroyed after the last detach. -q msqid Removes the message queue identifier msqid from the system and destroys the message queue and data structure associated with it. -s semid Removes the semaphore identifier semid from the system and destroys the set of semaphores 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. -Q msgkey Removes the message queue identifier, created with key msgkey, from the system and destroys the message queue and data struc- ture associated with it. -S semkey Removes the semaphore identifier, created with key semkey, from the system and destroys the set of semaphores and data struc- ture associated with it.
