Summary

1:47 with Jay McGavren

Let's review everything we've learned in this course.

Common Git Commands

  • Starting a repo
    • git init
  • Committing files
    • git add and git commit
    • git status
    • git log
  • Managing committed files
    • git rm and git mv
    • git revert
  • Working with remotes
    • git clone
    • git pull
    • git remote
    • git push

But there are other important features we haven't covered, such as branches and merging file changes. You can learn more about those in our Git Branches and Merging course.

Practice and Further Reading

  • Try using Git for all your Treehouse projects. If you have any saved project folders already, use git init to convert them to Git repos, then commit all your files. And for any new projects you create, use Git from the very start. Not only will this let you practice using Git, it will give you more protection against losing your work.
  • We've set up a copy of the practice repo from Stage 2 on GitHub. Try forking it, cloning it to a local repo, making changes, and then pushing them back up to your forked repo.

Atlassian, creators of BitBucket, have an excellent set of Git tutorials as well.

If you haven't installed or used Git on your computer yet, and you want to, see the Teacher's Notes section of this video's page.

On many systems, Git is configured to use the vi text editor by default. You may want to familiarize yourself with basic vi commands.
