              Select  a specific UPS, in case there is more than one connected
              via USB. Each option specifies an  extended  regular  expression
              (see  regex(7))  that  must  match the UPS's entire vendor/prod‐
              uct/serial string (minus any  surrounding  whitespace),  or  the
              whole  4-digit  hexadecimal code for vendorid and productid. Try
              -DD for finding out the strings to match.

              Examples:

                  -x vendor="Foo.Corporation.*"

                  -x vendorid=051d (APC)

                  -x product=".*(Smart|Back)-?UPS.*"
