there is a problem within the script. Probably an unset $VARIABLE, or
bad quoting.

"mv" needs two arguments, a 'from' and a 'to' file. If one is a
$VARIABLE and is unset, it is passed blank to the mv command and the mv
command then complains that it didn't get enough info.
(Just a guess, I don't know how the '.' part of the error fits)

Sorry I haven't read earlier in this thread. Did you try the method
given in Markus's article in GRASS Newsletter vol 3?


An alternate coastline can be obtained by the NOAA coastline extractor.
See the v.in.mapgen help page. Then v.type and v.centroids to make the
line into an area. (boundary+centroid = area)
