Hi, My first experiments with grass commands frustrate me. All tests I run end up with empty shp layers with 0 items.
I managed to “selectAll-copy" the log (but where is that log saved?) and this is the result.
Any comment will be rewarded with a beer next time you pass in Brussels.
Running QGis2.6.1 on OSX 10.10 Yosemite
thanks in advance
Joris
here’s the log
