[GRASS-user] Looping through features...

[Jonathan Greenberg]

Grass users:

	I was hoping to get a jump start on an analysis that requires that I 
perform a set of processes by looping through a set of poly features. 
My question is -- does anyone have an example of how to do this in GRASS 
(via bash scripting):

for i = 1, number of features in coverage
	extract feature i to a temporary file
	do something to feature i
end for loop

Vague enough?  My main issue is that I don't know how to query the 
number of features to begin the loop in a way that's usable to bash.
