You say you are trying to convert to a MapInfo file so you need to specify:
  -f "MapInfo File"
and the order of your files is wrong. The correct order is:
  destination_name   source_name
Try:
  ogr2ogr -f "MapInfo File" output test.shp
which should create a new directory 'output' containing the MapInfo files.
