[GRASS-user] add columns for x and y coordinates to vector db

[Brandon M. Gabler]

I have searched the archives, but cannot seem to find the answer.

I have a vector file, with 700 sites. I want to add columns for  
x_coord and y_coord (or easting and northing, or whatever), so that  
the columns represent the centroid coordinates of each site in the  
vector database. So, for CAT #1, I want the column 'easting' to  
update with the easting of CAT #1, and the column 'northing' to  
update with the northing for CAT #1, and so on for all CAT numbers in  
my file. I'm sure there is an easy script for v.db.update, but wanted  
to check with the list before reinventing the wheel. Has anyone  
created a script for such a thing, or is there a command within GRASS  
that I'm missing?

Thanks,
Brandon
