[GRASS-user] Running batch files

[Kris Nackaerts]

Dear all,

I'm new to GRASS and am interested in running analysis from the command 
line. My idea is to make a batch script that creates for example png files.

I did search for documentation, but could not find the right information 
to get me started. I created a .bat file (I'm working on windows, with 
GRASS 6.3), in this file, I set a lot of variables with 'set 
blabla=value'). Then, I try the following

set GRASS_PNGFILE=d:\test.png
g.gisenv set=DEBUG=3
g.region rast=slope -p
d.mon start = PNG
d.rast slope
d.mon stop PNG

I used filemon to check what's going on, and it seems each command is 
found, but nothing seems to happen. No DEBUG info, no single command 
provides any feedback, no PNG is created. The GUI of GRASS works OK.

I guess it's something really stupid I'm overlooking...

I try to use the Spearfish sample data.

Can someone provide some hints?
