NAME

       ipcrm - Removes message queue, semaphore set, or shared memory identifiers

SYNOPSIS

       ipcrm [-m shared_memory] [-M shared_memory_key] [-q message_queue] [-Q message_key] [-s semaphore_ID] [-S semaphore_key]

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

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       ipcrm: XCU5.0

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

OPTIONS

       Removes	the  shared  memory  identifier shared_memory. The shared memory segment and data structure associated with shared_memory are also
       removed after the last detach operation.  Removes the shared memory identifier, created with key shared_memory_key. The shared memory  seg-
       ment  and data structure associated with it are also removed after the last detach.  Removes the message queue identifier message_queue and
       the message queue and data structure associated with it.  Removes the message queue identifier, created with key message_key, and the  mes-
       sage  queue and data structure associated with it.  Removes the semaphore identifier semaphore_ID and the set of semaphores and data struc-
       ture associated with it.  Removes the semaphore identifier, created with key semaphore_key, and the set of semaphores  and  data  structure
       associated with it.

DESCRIPTION

       The  details  of the remove operations are described in the Section 2 reference pages for msgctl(), shmctl(), and semctl(). The identifiers
       and keys can be found by using the ipcs command.

EXAMPLES

       To remove the shared memory segment associated with shared memory identifier 18602, enter: ipcrm -m 18602
