In this module, you will get hands-on experience working with Git and its advanced concepts.

DevOps for Developers

Git is one of the most widely used version control tools, and is something that every developer should become comfortable with. In this module, you will get hands-on experience working with Git so that when it comes time to use it, you’ll be ready.

You’ll start by learning some of the more fundamental concepts such as initializing a Git repository, adding files to a repository, and how to commit changes. You’ll also learn how to clone a repository, and how to create branching.

You’ll then make your way to some more advanced concepts like Git stash, cherry-picking, working with multiple repositories, pushing code, and a lot more.

By the end of this module, you will have a proficient and working knowledge of Git which will serve you well throughout your career.

Git and GitHub

In the previous chapter, you stumbled upon pushing a change to another repository, and I mentioned that you needed a bare repository.


In this chapter, you will cover:

- What bare repositories are
- Force-pushing with `git push -f`
- The dangers of squashing and force-pushing with multiple users

By the end, you will have a better understanding of how to set up a central repository that users can pull and push to and understand how and why you can get into “Git merge hell.” Your understanding will help you figure out what to do when it happens.
