+.Sh NAME
+.Nm ipcrm
+.Nd remove the specified message queues, semaphore sets, and shared memory segments
+.Sh SYNOPSIS
+.Nm
+.Op Fl M Ar shmkey
+.Op Fl m Ar shmid
+.Op Fl Q Ar msgkey
+.Op Fl q Ar msqid
+.Op Fl S Ar semkey
+.Op Fl s Ar semid
+.Ar ...
+.Sh DESCRIPTION
+.Nm
+removes the specified message queues, semaphores, and shared memory
+segments.
+These System V IPC objects can be specified by their
+creation ID or any associated key.
+.Pp
+The following options are used to specify which IPC objects will be removed.
+Any number and combination of these options can be used:
+.Bl -tag -width indent
+.It Fl M Ar shmkey
+Mark the shared memory segment associated with key
+.Ar shmkey
+for removal.
+This marked segment will be destroyed after the last detach.
+.It Fl m Ar shmid
+Mark the shared memory segment associated with ID
+.Ar shmid
+for removal.
+This marked segment will be destroyed after the last detach.
+.It Fl Q Ar msgkey
+Remove the message queue associated with key
+.Ar msgkey
+from the system.
+.It Fl q Ar msqid
+Remove the message queue associated with the ID
+.Ar msqid
+from the system.
+.It Fl S Ar semkey
+Remove the semaphore set associated with key
+.Ar semkey
+from the system.
+.It Fl s Ar semid
+Removes the semaphore set associated with ID
+.Ar semid
+from the system.
+.El
+.Pp
+If the
+.Ar id
+or
+.Ar key
+argument is
+.Dq all
+then all entries of the appropriate type are removed.
+.Pp
+The identifiers and keys associated with these System V IPC objects can be
+determined by using
+.Xr ipcs 1 .
