2) I am not talking about my own scripts, I am talking about other peoples. I could obviously go through and debug them, and then check I haven't broken them on a couple of linuxes, and a mac without macports/homebrew but... I don't want to. Which is why the alias solution is nice, as it will only impact the interactive shell, not the scripts.
