    It is not clear what do you mean by 'Split'? Can you elaborate a bit more? – nash Mar 5 '17 at 18:20

If we have GDAL OGR with Spatialite support and liblwgeom (e.g. OSGeo4W):

ogr2ogr splitted_lake.shp lake.shp -dialect sqlite -sql "SELECT ST_Split(g1.geometry,g2.geometry) AS geometry FROM lake AS g1, 'boundary.shp'.'boundary' AS g2" -explodecollections
