information about all three resources: shared memory segments, message queues, and semaphore arrays.

resource options: -m, -q or -s.
-h, --help
Display help text and exit.
-V, --version
Display version information and exit.
Resource options

Write information about active shared memory segments.
-q, --queues
Write information about active message queues.

the last msgsnd(2) and msgrcv(2) operations on message queues, the time of the last shmat(2) and shmdt(2) operations on shared mem-
ory, and the time of the last semop(2) operation on semaphores.

The Linux ipcs utility is not fully compatible to the POSIX ipcs utility. The Linux version does not support the POSIX -a, -b and -o
options, but does support the -l and -u options not defined by POSIX. A portable application shall not use the -a, -b, -o, -l, and -u
options.
