list_running_app_ids [ -t <bundle-id> ]
Print a list of currently running Applications and associated
Bundle IDs, which may be useful in a Cask uninstall stanza, eg
uninstall quit: 'bundle.id.goes.here'
Applications attributed to Apple are excluded from the output.
With optional "-t <bundle-id>", silently test if a given app
is running, exiting with an error code if not.
See CONTRIBUTING.md for more information.
