   ^^^^^^ What are these question marks???
              ^^^^^^^ There needs to be a space between "-map" and
                      "[v]" or "[a]". You should also put "[v]" and "[a]"
                      in quotation marks.

Please show us an actual command line, and its complete, uncut console
output.

Probably solved with my second remark regarding the space and
quotation. But please give us more info.

Thanks,
