Git
Git is a version control system that lets you track who made changes to what when and has options for easily updating a shared or public version of your code on github.com. You will need a supported web browser.
You will need an account at github.com for parts of the Git lesson. Basic GitHub accounts are free. We encourage you to create a GitHub account if you don't have one already. Please consider what personal information you'd like to reveal. For example, you may want to review these instructions for keeping your email address private provided at GitHub.
Windows
Git should be installed on your computer as part of your Bash install (described above).
macOS
Please open the Terminal app, type git --version and press
Enter/Return. If it's not installed already,
follow the instructions to Install the "command line
developer tools". Don't click "Get Xcode", because that will
take too long and is not necessary for our Git lesson.
After installing these tools, there won't be anything in your /Applications
folder, as they and Git are command line programs.
For older versions of OS X (10.5-10.8) use the
most recent available installer labelled "snow-leopard"
available here.
Because this installer is not signed by the developer, you may have to
right click (control click) on the .pkg file, click Open, and click
Open in the pop-up dialog. You can watch
a video tutorial about this case.
Linux
If Git is not already available on your machine you can try to
install it via your distro's package manager. For Debian/Ubuntu run
sudo apt-get install git and for Fedora run
sudo dnf install git.
In this lesson we’ll do our work in the Desktop folder so make sure you change your working directory to it with:
$ cd
$ cd Desktop
