#!/bin/csh

foreach i ( `ls *.JPG | sed s/\.JPG//` )
	mv -f $i.JPG $i.jpg
end

echo >description

foreach i ( * )
	echo "$i, $i" >>description
end




Dunno how that translates into bash or if it's the most efficient way of
doing the job but it should work on the current directory.  Of course, to
recurse a tree you can just use find and the -exec option to call the
script.
