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.
