Here's another goodie. I've packaged Cameron Kaiser's (Tenfourfox blog) compiled bash and sh into an Installer package. Just install it like a normal package. It also backs up your current bash and sh binaries, unless they've already been backed up. It will work on any 10.4 or higher system. It is provided as is and I am not responsible if it breaks your machine. I've installed in on my machines and everything is working correctly.
