DESCRIPTION
       r.info reports some basic information about a user-specified raster map
       layer.  This map	layer must exist in the	user's current	mapset	search
       path.   Information about the map's boundaries, resolution, projection,
       data type, category number, data	base location and  mapset,  the	 time-
       stamp  and history are put into a table and written to standard output.
       The types of information	listed can also	be found in the	cats,  cellhd,
       and hist	directories under the mapset in	which the named	map is stored.

       The  user can save the tabular output to	a file by using	the UNIX redi-
       rection 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

NOTES
       On  large  maps,	 the  total number of cells in the map may not be dis-
       played with an accurate number. This is only cosmetic.

       Some standards (ISO-C90)	and compilers do not support the  'long	 long'
       type as a 64-bit	type. In the case that GRASS GIS was built with	such a
       compiler, an accuracy message may be displayed in the output of	r.info
       after Total Cells.

EXAMPLES
       Below  is  a full report	produced by r.info for the raster map slope in
       the North Carolina sample data base:
       r.info slope

       Alternatively, the output from r.info may be confined to	a  more	 terse
       subset  of  the	available  information by passing various flags	to the
       module:

       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
       location=nc_spm_08_grass7
       database=/grassdata
