[GRASS-user] shell script to break a vector line by a vector point

[Patton, Eric]

Michael,

a lot of scripts populate GRASS environment variables at the beginning of the script, so these variables can be called by name later inthe script:

 
# Capture environment variables.
eval `g.gisenv`
: ${GISDBASE?} ${GISBASE?} ${LOCATION_NAME?} ${MAPSET?}

You see this one a lot in the Grass add-on scripts.

~ Eric.

instead of

if [ ! -e "/usr/lib/grass/scripts/v.out.ascii.db" ] ; then

use

if [ ! -e "$GISBASE/scripts/v.out.ascii.db" ] ; then
