OPTIONS

17       -i, --id id
18           Show full details on just the one resource element identified by

21           output format for this option with the --list, --raw, --json or
22           --export option.
23
24       -g, --global
25           Show system-wide usage and limits of IPC resources. This option may
26           be combined with one of the three resource options: -m, -q or -s.
27           The default is to show information about all resources.
