Ipcrm

ipcrm is a Unix and Linux command which will mark System V interprocess communication API kernel entities for removal. Actual removal is deferred until the last connected process has detached.

System V IPC kernel entities are:


 * Shared memory (interprocess communication) segments
 * Message queues
 * Semaphore arrays

Implementations
On Linux, the ipcrm command is provided by the util-linux package.

The ipcrm command has also been ported to the IBM i operating system.
