An interactive shell is what you get when you boot up a terminal. Typically you would want utility-functions, aliases and coloring to become available at this point to make a ritcher experience.

I've added a bunch of functions to my configuration that I've found helpfull over the years. Most of these are all available directly from the shell as small programs. I haven't kept track of which of these I've created myself or which I've found on the great interweb unfortunately.
