Hi

I'm interested in finding the minimum cost path and its distance between
2 points in a cost raster.
I'm new in GRASS and I would appreciate some help and suggestions with
this issue.

Thanks in advance.

r.cost?

the help page has quite a bit of info,

as does section "C" of the Leicestershire GRASS Seeds Beginner's Tutorial.

R.cost (calculated from point #1), followed by r.drain (calculated for point #2).
