Extracting raster values at points for GRASS GIS

Question

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? — user30184, Dec 02 '16 at 11:57

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.
