How can I make GDAL to use a NTv2 grid to shift between some datums?
You have to tell GDAL where to find your shift gridin your file system:
cs2cs +init=epsg:4326 +to +proj=tmerc +lat_0=0 +lon_0=6 +k=1
+x_0=2500000 +y_0=0 +ellps=bessel
+nadgrids=D:\Karten\gdal\cs2cs\BETA2007.gsb +units=m in.txt >>out.txt
