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.
Yes: e.g., r.univar can do that:
GRASS 7.6.2git (nc_spm_08_grass7):~ >
g.region raster=boundary_county_500m
r.univar -g boundary_county_500m
n=616509
null_cells=506073
cells=1122582
min=0
max=199
range=199
mean=87.1764564669778
mean_of_abs=87.1764564669778
stddev=62.4325833627095
variance=3897.82746534167
coeff_var=71.6163352961689
sum=53745070
Usage in a shell script:
g.region raster=boundary_county_500m
eval $(r.univar -g boundary_county_500m)
echo $null_cells
506073
HTH,
Markus
