SYNTAX
ipcrm [ options ]
DESCRIPTION
Ipcrm will remove one or more specified messages, semaphores or
shared memory identifiers. The identifiers are specified by the
following options:
-q msqid removes the message queue identifier msqid from the
system and destroys the message queue and data
structure associated with it.
-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.
-s semid removes the semaphore identifier semid from the
system and destroys the set of semaphores and data
structure associated with it.
-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. Msgkey
is a decimal value.
-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. Shmkey is a decimal
value.
-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.
Semkey is a decimal value.
The details of the removes are described in msgctl(2), shmctl(2),
and semctl(2). The identifiers and keys may be found by using

CAVEAT
Ipcs(1) returns hex values. If you use it to return values for
use by iprcm(1) with the S, Q, or M switches, you must convert
the values to decimal before giving them to ipcrm.
