Hi, trying out v.net.path on yesterday's GRASS 7 OSGeo4W, the command runs through properly (correct result) but raises then an error:

Perhaps the pipe | is causing it? Markus _______________________________________________ grass-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-dev
