OPTIONS
       -i, --id id
	      Show full details on just the one resource element identified by
	      id.  This option needs to be combined  with  one	of  the	 three
	      resource	options: -m, -q or -s.	It is possible to override the
	      default output format for this option with  the  --list,	--raw,
	      --json or --export option.

       -g, --global
	      Show system-wide usage and limits of IPC resources.  This option
	      may be combined with one of the three resource options:  -m,  -q
	      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.

   Resource options
       -m, --shmems
	      Write information about active shared memory segments.

       -q, --queues
	      Write information about active message queues.

       -s, --semaphores
	      Write information about active semaphore sets.

   Output formatting
       -c, --creator

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

       -l, --list

	      that changed the access permissions for all facilities, the time
	      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.

       --time-format type
	      Display dates in short, full or  iso  format.   The  default  is
