[Qgis-user] Crash: merge shapefiles

[Hugo]

Hi Jonathan,

You can use ogr2ogr to recursively create those PRJ files.
You will need to make a bash script or bat file (depending on your platform
of choice) that can read all your input shapefiles from a folder and
execute the following command for each one of those:

ogr2ogr -a_srs EPSG:27700 output.shp input.shp

Obviously I'm assuming that you are using British National Grid hence the
option -a_srs EPSG:27700. You can change this if you have your data in
other projection.

Hope this helps.
Cheers,
