   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.
