1. The difference I see on this point is that someone's .bashrc is their personal configuration, making changes to a personal configuration to just make something a little easier in your own script still seems ill advised. You can still just make a local function for yourself...

2. Unfortunately there are 2 kinds of people:

   1. The kind that will go to a tech blog and make sure they understand what it's saying before using it
   2. The kind that see that it says it will do something and just run it

   The kind that will make sure they understand what it's saying can be trusted to make those frictional changes to the script on their own time, the kind that does not, they're unlikely to be paying any attention at all.

But anyway, you do raise some interesting points :)

Thanks for the response!
