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  facili-
                ties  in  the  specified zone (see zones(5)). The
                default is the zone in which the command is  exe-
                cuting.  This option is only useful when the com-
                mand 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),
