I have points shapefile and a raster file. For each point, I want to extract the raster value which overlaps that particular point. This has been done in QGIS (link below) but I was looking for a solution for GRASS GIS.

Extracting raster values at points using Open Source GIS?

EDIT: I found the blog below to be useful and posted the solution to the question below

    What GRASS documentation have you studied so far? Did you find anything useful?

The GRASS documentation on v.what.rast is very clear and concise. Have you tried: 

v.what.rast map=pnts raster=elevation column=height

Where pnts is your vector point layer; elevation is your raster and height is the attribute that will be updated.
