Hi Martin, Carlos,

two quick observations:

This is a bash-ism AFAIK (still needs to be eliminated in some scripts):
   export LC_NUMERIC=C


Before doing that the current region should be saved. In an older mail
from Glynn it was described how to solve it in an elegant way:
   #set to current input map region
   g.region rast=$GIS_OPT_raster

Of course the current region should be restored at the end of the script
and in case of "trap" (which isn't there, see cleanup() in other scripts).
