r.stats (grass5)

Hi Markus,
o.k. but If I want only the unique values?
It's working with r.stats -1 DEM | sort -u

but this is terrible slow. Is there a other possibility to do that?

this is quite easy:
r.stats -1 dgm25
177.0060272217
176.5745239258
176.0958557129
174.9282073975
173.8042144775
...

or with coordinates:
r.stats -1g dgm25
3571612.5 5765037.5 144.0717010498
3571637.5 5765037.5 144.0996246338
3571662.5 5765037.5 144.0055541992
3571687.5 5765037.5 144.1030426025
3571712.5 5765037.5 144.6298828125
3571737.5 5765037.5 145.0991973877

Check for NULL suppresion:
  -n Suppress reporting of any NULLs
  -N Suppress reporting of NULLs when all values are NULL

Kind regards
