[GRASSLIST:8634] connecting points with lines

GRASS GRASS user
1

I think this is an easy question, but I can’t seem to readily find the answer in the documentation. Is there a simple way to connect lines (create topology) in a rater point layer? Say, for example, a vector layer with two points, A and B. Is there a simple way to have GRASS connect the two with a line from A to B? Displaying this vector layer would then show a line, rather than just the two points. I need to do this from the command line, as it is part of a script.

Thanks!

are you working with network analysis?

v.net.path would not solve your problem?
