NAME

ipcrm– Remove a message queue, semaphore set, or shared memory ID

SYNOPSIS

ipcrm [-l slabel] [-m shmid] [-q msqid] [-s semid] [-M shmkey] [-Q msgkey] [-S semkey…]

DESCRIPTION

ipcrm removes one or more messages, semaphores, or shared memory identifiers.

The invoking process must have both mandatory and discretionary access to the IPC or must be suitably privileged.

OPTIONS

The identifiers are specified by the following options:

-l slabel

Use the specified sensitivity slabel (instead of the current sensitivity label) of the process in conjunction with subsequent -M, -Q, and -S options.

-m shmid

Remove the shared memory identifier shmid from the system. The shared memory segment and data structure associated with it are destroyed after the last detach.

-q msqid

Remove the message queue identifier msqid from the system and destroy the message queue and data structure associated with it.

-s semid

Remove the semaphore identifier semid from the system and destroy the set of semaphores and data structure associated with it.

-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.

-Q msgkey

Remove the message queue identifier, created with key msgkey, from the system and destroy the message queue and data structure associated with it.

-S semkey

Remove the semaphore identifier, created with key semkey, from the system and destroy the set of semaphores and data structure associated with it.

The details of the removes are described in msgctl(2), shmctl(2), and semctl(2). Use the ipcs command to find the identifiers and keys.

ENVIRONMENT VARIABLES

See environ(5) for descriptions of the following environment variables that affect the execution of ipcrm: LANG, LC_ALL, LC_CTYPE, LC_MESSAGES, and NLSPATH.

ATTRIBUTES

See attributes(5) for descriptions of the following attributes:

SUMMARY OF TRUSTED SOLARIS CHANGES

There is a new option, -l, for operating on keys at a specific sensitivity label. Appropriate privilege is required to override failed access checks. For more information on required privileges, see the IPC_RMID option in msgctl(2), semctl(2), and shmctl(2).
