	      resource	options: -m, -q or -s.	It is possible to override the

	      --json or --export option.

       -g, --global
	      Show system-wide usage and limits of IPC resources.  This option

	      or -s.  The default is to show information about all resources.

       -h, --help
	      Display help text and exit.

       -V, --version
	      Display version information and exit.

       -e, --export
	      Output data in the format of NAME=VALUE.

	      of  the last msgsnd() and msgrcv() operations on message queues,
	      the time of the last shmat() and shmdt()	operations  on	shared
	      memory,  and  the	 time  of  the last semop() operation on sema-
	      phores.
