hi everyone,
plz help me out with this problem:
I have a vector map which displays the coastline of a country and I would like to draw a
buffering line joining all points which is at a certain distance “d” from the coastline.
so given the coastline vector map and the distance “d” is there a command in GRASS which will
draw this buffering line around the coast?

If you are using GRASS5.0, there is no command for creating buffers around
a vector. You will to use v.to.rast to make your vector map into a raster
map and then use r.buffer.

You can only make a postscript map by ps.map using offset option for vector.

v.buffer exists, but is not (yet) integrated:
http://grass.itc.it/outgoing/
-> v.buffer.tar.gz (source code)
-> v.buffer.txt
We need someone to test it and make it ready for GRASS integration.
