[GRASS-user] Re: script to generate georeferenced jpeg colored images from FCELL/CELL rasters

[G. Allegri]

Thanks Glynn. I'm writing my first grass scripts...
About region settings do you mean to use something like this?:

g.region -u rast=$RAST save=region.tmp.$$
WIND_OVERRIDE=region.tmp.$$
export WIND_OVERRIDE
(my code)
g.remove region=region.tmp.$$

The exec command obviously was an error!
