Hello, I'm new to GRASS, coming from an Arc* background, and often find that I'm approaching things from the wrong direction. I'm using GRASS 6.4 with the wxPython GUI.
I would like to graphically select multiple features from a large vector file and edit an attribute of those features. (I have a poorly classified polygon shapefile of hydrology and want to separate the rivers from the lakes). How can I go about this. With v.what.vect I seem to be able to only edit one feature at a time.
The name of the module should remind you of old AI stuff... it's a shell
script, so not working with grass70, and only tested with postgresql
database connection (it will probably fail with dbf driver). Grass has
to be launched in text mode (type "grass64 -text" from your shell
prompt), and there must be an open monitor (d.mon).
Good luck !
Vincent.

a couple other things to try not mentioned yet- (automated)
v.clean remove small areas (extracts big lakes)
if rivers are lines not polygons you could v.extract only lines
or areas.
