       convert from old versions of the interface configuration file to the current format.

-a,--auto
           Only match interfaces that are marked as auto.

       -h,--help
           Display supported options to ifquery.

       -i,--interfacesFILE
           Use FILE as the config database.

       -p,--propertyPROPERTY
           Print the values of matching properties for an interface.

       -r,--running
           Print the interface names that are marked as running in the state database.

       -s,--state
           Query the state database instead of the config database.

       -D,--dot
           Generate a dependency graph that can be used with GraphViz dot(1).  Used with --list.
