[GRASS-user] shell script

[Sandile Gumede]

Hi

I'm trying to run the script below but it's giving me an error saying
default region is not set.

Which command should I use to set the default region and do I put it?

#!/bin/sh

#variable to customize:
# path to GRASS software main directory
GISBASE=/usr/lib/grass64
# path to GRASS database
GISDBASE=$HOME/grassdem

# nothing to change below
MAP=$1
LOCATION=$2


# generate temporal LOCATION:
TEMPDIR=FLOODS
mkdir -p $GISDBASE/$TEMPDIR/PERMANENT

# save existing $HOME/.grassrc6
if test -e $HOME/.grassrc6 ; then
mv $HOME/.grassrc6 /tmp/$TEMPDIR.grassrc6
fi

echo "LOCATION_NAME: $TEMPDIR" > $HOME/.grassrc6
echo "MAPSET:PERMANENT"             >> $HOME/.grassrc6
echo "DIGITIZER: none"        >> $HOME/.grassrc6
echo "GISDBASE: $GISDBASE"    >> $HOME/.grassrc6
export GISBASE=$GISBASE

# Create a WIND file with minimal information and no projection:
echo "proj:       0

" > $TEMPDIR/$LOCATION_NAME/$MAPSET/WIND

# Copy WIND-file to DEFAULT_WIND:
cp $TEMPDIR/$LOCATION_NAME/$MAPSET/WIND \
 $TEMPDIR/$LOCATION_NAME/$MAPSET/DEFAULT_WIND

# Set default database driver:
echo "DBF_DRIVER: dbf
DB_DATABASE : $GISDBASE/$LOCATION_NAME/$MAPSET/dbf/
" > $TEMPDIR/$LOCATION_NAME/$MAPSET/VAR

export PATH=$GISBASE/bin:$GISBASE/scripts:$PATH
export LD_LIBRARY_PATH=$GISBASE/lib:$LD_LIBRARY_PATH
export GIS_LOCK=$$
export GISRC=$HOME/.grassrc6
db.connect driver=dbf database='$GISDBASE/$LOCATION_NAME/$MAPSET/dbf/'

# this should print GRASS version used:
g.version

g.proj --quiet -c epsg=4326

g.region --quiet -s  n=90 s=-90 w=-180 e=180 res=1

# other calculations go here....

# import rainfall data set.
# cd /home/tgumede1/grassdem

r.in.gdal input=$HOME/grassdem/TRMMLast1day.tif output=rainfall

g.region rast=rainfall
