DESCRIPTION

     The  ipcrm command  removes  one or  more message  queue,
     semaphore set, or shared memory identifiers.

FLAGS

     -lmsqid     Removes  local information  about the  remote
                 queue  msqid  without   removing  the  remote
                 queue.
     -Lmsgkey    Removes  local information  about the  remote
                 queue  msgkey  without  removing  the  remote
                 queue.
     -m shmid    Removes the  shared memory  identifier shmid.
                 The shared memory  segment and data structure
                 associated with shmid  are also removed after
                 the last detach.
     -M shmkey   Removes the shared memory identifier, created
                 with key  shmkey.  The shared  memory segment
                 and  data structure  associated  with it  are
                 also removed after the last detach.
     -q msqid    Removes  the message  queue identifier  msqid
                 and  the  message  queue and  data  structure
                 associated with it.
     -Q msgkey   Removes the message queue identifier, created
                 with key  msgkey, and  the message  queue and
                 data structure associated with it.
     -s semid    Removes  the semaphore  identifier semid  and
                 the  set  of  semaphores and  data  structure
                 associated with it.
     -S semkey   Removes  the  semaphore  identifier,  created
                 with key  semkey, and  the set  of semaphores
                 and data structure associated with it.

     The  details of  the remove  operations are  described in
     msgctl, shmctl,  and semctl  in the AIX  Operating System
     Technical  Reference.  The  identifiers and  keys can  be
     found by using the ipcs command.
