sure, see r.profile and r.transect modules.

If your line is already a vector line and not just a collection of
coordinates, you could use 'v.out.ascii format=standard' first to get
the line's coordinates. r.profile will take input from stdin, so with a
little awk magic you could pipe v.out.ascii directly into r.profile. If
you figure that out, maybe post it back here so we could add it as an
example on the r.profile help page.


see also the profile tool in the GIS.m GUI menu for interactive profile
creation. (you could display the line and trace over it)
