The user can save the tabular output to a file by using the UNIX redirection mechanism (>); for example, the user might save a report on the soils map layer in a file called soil.txt by typing:
r.info map=soils > soil.txt
Some standards (ISO-C90) and compilers do not support the 'long long' type as a 64-bit type. In the case that GRASS was built with such a compiler, an accuracy message may be displayed in the output of r.info after Total Cells.

Output in shell script style, useful for eval (eval `r.info -g slope`):
r.info -g slope north=228500 south=215000 east=645000 west=630000 nsres=10 ewres=10 rows=1350 cols=1500 cells=2025000 datatype=FCELL ncats=255
Output the map data range:
r.info -r slope min=0 max=38.68939
Output the extended map data metadata in shell style:
r.info -e slope map=slope mapset=PERMANENT project=nc_spm_08_grass7 database=/grassdata date="Tue Nov 7 01:11:23 2006" creator="helena" title="South-West Wake county: slope in degrees (slope_ned10m)" timestamp="none" units="none" vdatum="none" semantic_label="none" source1="raster elevation file elev_ned10m" source2="" description="generated by r.slope.aspect" comments="slope map elev = elev_ned10mzfactor = 1.00 format = degreesmin_slp_allowed = 0.000000"
Finally, the output from r.info can be output in JSON by passing the format=json option.
r.info slope format=json
