You almost certainly have it already. If not,
Debian-based (like Ubuntu):
sudo apt-get install git
Red Hat-based (like Fedora):
sudo yum install git
Note: I haven’t used Fedora in many years, so double check that.
If you have a Mac, you must use Homebrew. Then installing git is easy:
brew install git
It’s a good idea to update
brew and your
brew packages first:
brew update brew upgrade
Download the Git for Windows installer from Git’s official downloads page and run it. Then you’ll also have
git-bash, which gives you a Bash shell – a superior alternative to
cmd or Power[sic] Shell.
