Note that there is more than one version of rename on Linux systems.
Their usage and syntax varies. I believe Stephen is using Ubuntu
10.04. If so the one Lennart describes will match.

There is a different version provided in the util-linux-ng package. In
Ubuntu 10.04 the command for this version is rename.ul but in other
distributions it may be what you get if you just use rename.

Try "rename -h" first to find verify that it works the way you expect.
