DESCRIPTION
       nm-online  is  a utility to find out whether we are online. It is done by asking NetworkManager about its status. When run, nm-online waits
       until NetworkManager reports an active connection, or specified timeout expires. On exit, the returned status code should be  checked  (see
       the return codes bellow).
