56 r.info reports some basic information about a user-specified raster map
57 layer. This map layer must exist in the user's current mapset search
58 path. Information about the map's boundaries, resolution, projection,
59 data type, category number, data base location and mapset, the time‐
60 stamp and history are put into a table and written to standard output.
61 The types of information listed can also be found in the cats, cellhd,
62 and hist directories under the mapset in which the named map is stored.
63 The user can save the tabular output to a file by using the UNIX redi‐
65 rection mechanism (>); for example, the user might save a report on the
66 soils map layer in a file called soil.rpt by typing: r.info map=soils >
67 soil.rpt
68
70 On large maps, the total number of cells in the map may not be dis‐
71 played with an accurate number. This is only cosmetic.
72 Some standards (ISO-C90) and compilers do not support the 'long long'
74 type as a 64-bit type. In the case that GRASS was built with such a
75 compiler, an accuracy message may be displayed in the output of r.info
76 after Total Cells:.
77 Below is the report produced by r.info for the raster map slope in the
79 Spearfish sample data base.
