 NAME
ipcrm - remove a message queue, semaphore set, or shared memory ID
 SYNOPSIS

ipcrm [-z zone] [-m shmid] [-q msqid] [-s semid]
 [-M shmkey] [-Q msgkey] [-S semkey]


 DESCRIPTION

ipcrm removes one or more messages, semaphores, or shared memory
identifiers.
 OPTIONS

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.
