ipcrm - remove a message queue, semaphore set, or shared memory
ID
ipcrm [-z zone] [-m shmid] [-q msqid] [-s semid]
[-M shmkey] [-Q msgkey] [-S semkey]
ipcrm removes one or more messages, semaphores, or shared
memory identifiers.
The following option is supported:
-z zone
Keys specified by other options refer to facilities in
the specified zone (see
zones(7)). The default is the zone in which the
command is executing. 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
structure associated with it.
-S semkey
Removes the semaphore identifier, created with key
semkey, from the system and destroys 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.
