This first time I used a mac where zsh was the default, I was confused for quite a bit of time when it would not run something I was used to doing. I kept looking up errors on the internet until I came across someone's post with a reply asking if they were using Terminal on a new OS X. Sure enough, this was a new mac as well. Now I know one of the first steps for me with a new Mac is change default shell. I'm way too old and set in my ways to care to learn a new shell. Choosing a shell, IDE, font, etc are games for youth.

I learned to consistently use shebangs at the top of scripts while working with the first zsh user I knew. Or might have been fish. No i think he started in zsh and moved to fish. Every time I forgot, his environment was busted. And he sat a cubicle and a half away from me, so I got fast feedback.

		Just last week I found myself trying to explain shebang to someone that knows nothing of coding, command line interfaces, or what shells are. At one point, I was wondering where it was I should have stopped talking, but it was definitely well before I finished.
