imagery group files
in the GRASS data base.
OPTIONS
If the user runs g.findfile without command line arguments,
he will be prompted for the names of a GRASS element, file, and mapset,
through the standard
parser.
Parameters:
- element=name
- The data base element (i.e., directory within a GRASS
mapset) to be searched.
- mapset=name
- The mapset in which to search for the specified file
name. If not specified, all mapsets in the user's
GRASS search path are searched. Otherwise, the specified
mapset is searched. As a convenience, if specified as a
single dot (.) only the current mapset is searched.
- file=name
- The name of a GRASS data file (of the stated
element type) for which to search.
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 name=name`
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
