Git Rebase Fork - Shell-Bash

Git is a widely used version control system for software development. It allows developers to track changes made to their code, collaborate with others, and manage different branches of a project.

One important feature of Git is the ability to merge changes from one branch to another. This is usually done using the git merge command. However, there is another way to merge branches called git rebase.

What is Git Rebase?

Git rebase is a way to apply changes from one branch to another by modifying the commit history of the target branch. This is different from git merge, which creates a new merge commit that combines the changes from both branches.

With git rebase, the changes from one branch are replayed on top of the target branch, creating a linear history that incorporates all the changes made on both branches.

Forking and Rebase

Forking a repository means creating an independent copy of the repository. This can be useful if you want to work on a project without affecting the original project's codebase. When you fork a repository, you create a new branch that is a copy of the original repository's master branch.

If the original repository is updated while you are working on your forked version, you will need to incorporate those changes into your fork. This can be done using git rebase fork.

Here are the steps to rebase a forked repository:

1. First, you need to add the original repository as a remote. This can be done using the command git remote add upstream <original-repo-url>. This creates a new remote called upstream that points to the original repository.

2. Then you need to fetch the latest changes from the original repository using git fetch upstream.

3. After that, checkout the branch you want to rebase on top of the changes from the original repository.

4. Finally, run the command git rebase upstream/master to apply the changes from the original repository to the current branch.

Conclusion

Using git rebase fork is a powerful way to keep your forked repository up to date with the original repository. It allows you to incorporate changes made by other developers without affecting your own work. By understanding how to use git rebase, you can become a more efficient and effective software developer.
