Processing CORINE Land Cover 2006 Seamless Vector Data with OGR/GDAL's ogr2ogr and BASH

Lately I posted about using R to programmatically download all (43 zip-files) seamless 2006 vector data of CORINE Land Cover (see here). In this follow-up I share two bash-scripts with OGR/GDAL's ogr2ogr which I used to extract features by extent (Austria/Tyrol) and to combine all seperate shp-files into one by appending the dbfs. The style I used for the map is also available with german labels HERE.
