[GRASSLIST:10025] which is the best method to calculate the distance between two points?

[Patricio Antonio Toledo Peña]

dear grass list,

i have two points, they do not belong to a vector map, i have found that i
can obtain the distance (in UTM and LAT/LONG locations) with this (ugly)
trick

grass$ r.profile map=rmap profile=x1,y1,x2,y2 2> temp_file
grass$ distance=$(awk '/length/{print $4}' < temp_file)

this method needs a query to a raster map, which is unnecessary, is
something like d.measure available in r.* commands?

Thanks in advance
