Hi Listers,
r.fillnulls exits with an error if the input map has no holes.
r.fillnulls one step in a bash script. The processing is stopped if
r.fillnulls writes no output because of an error.
Thus i would like to check if any holes need to be filled. If this is
the case run r.fillnulls and if not just copy input to output map name.
Is there a handy command which reports if there are any NULLs in the
raster map. The output of the command shall be used in a bash if
construction.
thanks
robert
