I would like to extract some features of vector map based on the attribute label. The online manual says that I should use the n flag. But when I use the following command:
I get the error message: n is not a valid flag. But why and what can I do else?
(I am using Grass Version 5.0.1 on Suse-Linux)
Is there a way of reclassify a vector map based on the attribute label. If yes, I would reclassify the attributes by the attribute label and do a v.extract based on the attributes.

v.reclass uses the category number, not the label. But it shouldn't be too
hard to write a script to make the lables be the categoriy numbers,
provided that these labels are integers since categories cannot be text or
float.
