[GRASSLIST:3431] Re: batching the export process

Hi Kirk,
Speaking of experience, you don't want to run a long script in a current GRASS 
session, unless you have plenty of time before you and no need of GRASS 
meanwhile. The easiest is to run an alternate session. From various info 
gathered on the mailing list, I came with this small script (a complete 
ripoff from Glynn Clements <glynn.clements at virgin.net>): you have to define 
the location and mapset (existing ones) in the first lines, add your export 
commands in the third section, and just run the script. That's OK as long as 
your export commands remain in the same mapset and that you don't intend to 
display anything (else you may run into some troubles).
I guess that the easiest would be to use r.out.tiff for your DOQQs. Just 
browse through your rasters, you can access the list in 
$GISDBASE/$LOCATION_NAME/$MAPSET/cell
Consider the size of the files if you have a lot of them...

Regards
P.
