What information does your shapefile contain, elevation points? If so, and if they are regularly spaced, you can probably use the GMT utility xyz2grd, http://gmt.soest.hawaii.edu/gmt/doc/gmt/html/man/xyz2grd.html. Otherwise you will need to interpolate the points into a regular grid, and my only experience doing this is with ArcGIS's Spatial Analyst. I would imagine GRASS has similar capability though. I'd be curious to hear other suggestions as well.
