This is quite elegant for my taste. Ok, apart from the missing $ in
the sed patterns, which I'd write as:
sed -e 's/JPG$/jpg/'
You can also use basename(1) for something like this:
for fname in *.JPG ;do mv ${fname} "`basename ${fname} jpg`" ;done
But this only proves that there are many many ways of doing the same
thing, when you're on a Unix command line. If what you used worked for
you, then why bother to prove it inelegant ?
