[Qgis-user] batch shapefile reproject?

[Nick Ves]

I think that macos have their native bash interpreter (aka the TERMINAL).

if so a simple

for file in `ls *.shp` ; do ogr2ogr <ogr2ogr-commands> $file; done


should do the trick. Just run it from the terminal inside the folder you
have your shapes, or write it down to a file, make it executable (chmod +x
the-script.sh) and run it (double click?)
 The above might need some fine-tuning thats the general idea :)

happy scripting
