localhost:~ ssen$ type ipcrm
ipcrm is /usr/bin/ipcrm
localhost:~ ssen$ man ipcrm |
head
ipcrm(1) BSD General
Commands
Manual ipcrm(1)
NAME
ipcrm -- remove
the specified message queues, semaphore sets, and shared
memory
segments
SYNOPSIS
ipcrm [-q msqid]
[-m shmid] [-s semid] [-Q msgkey] [-M shmkey]
[-S
semkey] ...
