Sorry for coming back to this older mail. My question is: rather than 
running the somewhat time-consuming r.category to get a list with the 
categories and their labels, can I not simply use:

cat cats/crossmap # ..and there I have my text file with the labels?

(Given that I want all categories for the full map extent in the native 
resolution.)
