There is one advantage of this script over an equivalent document: it provides the instructions in the same context that it's being used (the command shell). Unless we have script shells that can universally launch a web document side-by-side from the shell prompt where it needs to be used, having it being displayed from the shell itself step by step will reduce the mental load required to follow the instructions. Also, the benefit of having an already semi-automated process in order to build a script in the future is not negligible.
