   Parameters:
       element=string
           Name of an element

           Default:

DESCRIPTION

       g.findfile  is  designed  for  Bourne  shell  scripts that need to search for mapset elements, including:
       raster, vector maps, region definitions and imagery groups.

       The list of element names to search for is not fixed; any subdirectory of the mapset directory is a valid
       element name.

       However,  the  user   can   find   the   list   of   standard   GRASS   element   names   in   the   file
       $GISBASE/etc/element_list.  This  is the file which g.remove/g.rename/g.copy use to determine which files
       need to be deleted/renamed/copied for a given entity type.

OUTPUT

       g.findfile writes four lines to standard output:
       name='file_name'
       mapset='mapset_name'
       file='unix_filename'
       fullname='grass_fullname'
        The output is /bin/sh commands to set the variable name to the GRASS data base file name, mapset to  the
       mapset  in  which  the  file  resides,  and  file  to  the full UNIX path name for the named file.  These
       variables may be set in the /bin/sh as follows:
       eval `g.findfile element=name mapset=name file=name`

       For example (raster map):
       eval `g.findfile element=cell file=mymap`

NOTES

       If the specified file does not exist, the variables will be set as follows:
       name=
       mapset=
       fullname=
       file=
        The following is a way to test for this case:
       if [ ! "$file" ]
       then
            exit
       fi
        Note that region files are searched as element=windows.
