Easy:

	for f in *.[ch]; do
		mv $f old.$f
	done

CLUNK!

Now changing the `extension' like your example above is harder:

	for f in *.[ch]; do
		mv $f `echo $f | sed 's/^\([^\.]*\)\.c$/\1.h/'`
	done

CLUNK CLUNK!

And if you like visual feedback add a "echo $f" in there.

It may look ugly but at least it's succint ;-)...
