In 1979 Unix v7 started being distributed with the original Bourne Shell. Simply, it’s a program that sits at /bin/sh and runs in the terminal. You may ask, what’s the difference between a shell and the terminal?
I went to reinstall RVM (Ruby Version Manager) and got a message that the command wasn’t available. I realized, after fiddling around for a while that I didn’t have bash setup, and I had tried to run the standard quick install… just go to the blog entry. 😛 You can see all the bash & snippets there, they however won’t display here well at all.
