01: Gearing Up

In this exercise you'll either find or install the software you need to complete the course. You don't need much, just a Terminal, Text Editor, and two programs named grep and sed.

macOS/OSX

• Terminal - On macOS you'll need to access your Terminal program to run the exercises. You can find Terminal in your Applications directory, or by hitting cmd-spacebar and typeing "terminal". Once it's running, right-click on it in your Dock and select "keep in dock" so that it's always there.
• Text Editor - You need an editor that can work with only text. I recommend Geany as it's simple enough to use, but not so simple it's useless.
• grep - You should already have this on your computer. Open your terminal and type grep -v to run it.
• sed - You should also have this too. In the same Terminal type sed -v confirm it works.

You'll be using the command line (Terminal) in this course, but not very much. Most of the commands will be explained to you and demonstrated, but I may create a free command line crash course if enough people need it.
