Why not just use the mv command rather than a perl script? Of course, if
you have a large number of such files to rename, then the perl script
may be better, I usually do something like this:

find . -name '*.JPG' -exec mv {} `cat {} | sed -e 's/\.JPG/.jpg/'` \;

The above will rename all .JPG files to .jpg files in the current and
all its sub-directories.

But maybe I'm old fashioned:-)

Tony.
