# If you want the union, run the command twice and concatenate the results.

`uses` [<options>] <formula>
Show formulae that specify <formula> as a dependency. When given multiple
formula arguments, show the intersection of formulae that use <formula>.
By default, `uses` shows all formulae that specify <formula> as a required
or recommended dependency for their stable builds.
