Hi Hamish,
Maybe it could be usefull to do a backward step.

I should convert a shapefile into a raster file (GeoTIFF format) at a 
given resolution and I want to use the GRASS modules as a command line 
tools.
I followed the instructions in the chapter "Automated usage of grass" in 
the Markus's book and I created a bash script in order to prepare the 
grass enviroment:

#!/bin/bash
LOCATION=test

GISBASE=/usr/local/grass-6.5.svn
GISDBASE=/usr/local/share/grassdata

rm $HOME/.grassrc6
rm -rf "$GISDBASE/$LOCATION" #cleaning LOCATION

TMPDIR=$$.tmp
mkdir -p $GISDBASE/$TMPDIR/temp

echo "LOCATION_NAME: $TMPDIR" > $HOME/.grassrc6
echo "MAPSET: temp" >> $HOME/.grassrc6
echo "DIGITIZER: none" >> $HOME/.grassrc6
echo "GISDBASE: $GISDBASE" >> $HOME/.grassrc6

export GISBASE=$GISBASE
export GISRC=$HOME/.grassrc6
export PATH=$PATH:$GISBASE/bin:$GISBASE/scripts

After these lines I run the v.in.ogr module to import the vector:
v.in.ogr -o -e dsn=./test_data/test_data.shp output=grass_map

And the following is the error i get.
ERROR: region for current mapset is not set
run "g.region"

I tried to get the g.region help message, also I tried to reset the 
region (with g.region -d) and to set a default region (with g.region -s) 
but I get always the same error.

I'm very new with GRASS and I cannot understand if there is a problem in 
the installation, or it is a bug (as it seemed), or I'm not working in 
the proper way.

Thanks (also for the patience)
