[GRASSLIST:596] How to program a little script

[giglio.antonio at katamail.com]

Hi folks,
I have to program a little script that, starting from 2 points (A and B) on a raster map (a DEM), calculate first 3 shortest going-down paths (from A to B).
It seems to be easy, but this is the first time i try to program GRASS and I don't know how to proceed.
Thank you,
Antonio Giglio.
