What is Git?

Git is Source Control Management Software. It is a project management tool, with the goal of maintaining a digital projects history. It does this by tracking changes of the contents within a folder/directory. It also makes it easy to share projects remotely, across the internet, without having to transfer the entire project.

Vocabulary

  1. Repository
    • Location where changes are tracked.
  2. Commit
    • Set of changes to apply to the projects history.
  3. Branch
    • A collection of commits.

Commands

     user:~/project/tutorial$ git init
Enter fullscreen mode Exit fullscreen mode
     user:~/project/tutorial$ git add .
Enter fullscreen mode Exit fullscreen mode
  • This tells Git that you would like to track the history for all files and folders within this directory.
  • See git-add
     user:~/project/tutorial$ git commit -m "Initial Commit"
Enter fullscreen mode Exit fullscreen mode

You now have a repository that contains:

  • Any files within this folder.
  • A "master" branch.
  • A single commit with a message of "Initial Commit".

In order to add more changes, you should repeat the second and third commands any time you make changes to the contents of the folder.
Note: Make sure you change the message for your commits, because that will be the quickest way to tell what you changed with the commit.

     user:~/project/tutorial$ git revert <commit>
Enter fullscreen mode Exit fullscreen mode
  • Undo the changes recorded within a commit. Does not erase the original commit, merely undoes the changes that were recorded.
  • The commit must be done through a reference. You can find the hash(ID) for a commit by running "git log". You cannot specify a message.
