'v.info -g' will give you the bounding box, easy peasy.



MAP=your_map_name

v.db.addcol $MAP column="north DOUBLE PRECISION, \
  south DOUBLE PRECISION, east DOUBLE PRECISION, west DOUBLE PRECISION"

eval `v.info -g $MAP`

echo "UPDATE $MAP SET north = $north, south = $south, \
  east = $east, west = $west" | db.execute
