Alex's Rails Cheat Sheet

I think the most confusing thing that I have found about Ruby on Rails so far has been the transition from (trying to) write code myself to the use of the fabled "Rails Magic". So, to help my own understanding of a few core Ruby on Rails concepts, I have decided to write something on what I think is a CRITICAL topic... the idea of Convention over Configuration and why (in my mind) it is the most important thing that helps Rails become magic!

(This may be a topic that we cover in more detail in class but as I said, I'm writing this for my own understanding... I hope it helps someone else understand things too... Perhaps you can give me a hand when I'm crying next week!)

##Convention over configuration ###What does this "actually" mean...

A leak-proof tee to the clipboard

This script is modeled after tee (see [man tee][2]) and works on Linux, macOS, Cygwin, WSL/WSL2

It's like your normal copy and paste commands, but unified and able to sense when you want it to be chainable.

This project started as an answer to the StackOverflow question: [How can I copy the output of a command directly into my clipboard?][3]
