What are you trying to achieve? Splitting a shapefile into smaller pieces by grouping features with common attribute(s) as a kind of pre-classification? Then ogr2ogr might help you. See http://www.gdal.org/ogr2ogr.html and http://www.gdal.org/ogr/ogr_sql.html how to use this tool. Also http://mapserver.org/optimization/vector.html might help you.
