           Name of input raster map

DESCRIPTION  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 timestamp 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  redirection  mechanism
       (>);  for  example,  the  user might save a report on the soils map layer in a file called
       soil.rpt by typing: map=soils > soil.rpt


       On large maps, the total number of cells in the map may not be displayed 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 was built with such a compiler, an accuracy  message  may  be
       displayed in the output of after Total Cells:

        Alternatively, the output from may be confined to  a  more  terse  subset  of  the
       available information by passing various flags to the module: -rst slope
       datatype=FCELL -g slope
