ipcs:
-q Writes information about active message queues

-o
            Writes the following usage information:
              *    Number of messages on queue
              *    Total number of bytes in messages in queue for message queues
              *    Number of processes attached to shared memory segments

-m
Writes information about active shared memory segments.

secumid$ ipcs -qo | grep secumid
q 123731977 0x4207803a --rw-rw-rw- secumid staff 0 0
q 104857729 0x4107803a -Rrw-rw-rw- secumid staff 0 0

secumid$ ipcs -m | grep secumid
m 16777365 0x4707803d --rw------- secumid staff

-------------------------------------------------------------------------------------------------------------------------
secumid$ ipcs | grep secumid | awk '{printf("ipcrm -%s %s;\n", $1, $2)}'
ipcrm -q 123731977;
ipcrm -q 104857729;

Removes the shared memory identifier SharedMemoryID. The shared memory segment and data structure associated
with SharedMemoryID are also removed after the last detach operation.

-q MessageID
Removes the message queue identifier MessageID and the message queue and data structure associated with it.

$ ipcs -qo | grep secure
q 12582913 0x4200b308 --rw-rw-rw-   secure    staff         0         0
