I was going about my business, as you do, having used the LocationChanger script and launchd agent to automatically switch my Mac between my home and non-home network locations. Of course, I decided I could do it a little better, and got to work.

Here is the result: AutoLocation.

I learned a few new things while cooking this up, including how to actually deal with arrays in bash, a nifty thing called process substitution (which resulted in my favorite line in the whole script), and a great way to return arbitrary values into variables from functions.

I really like it when I learn new things on the way to solving a problem for myself. It’s the best way to learn something.
