What is the use of fork in git? how to use?

Git is a very powerful distributed version control system. Its branches, merges and tags are very convenient. These functions make collaborative development simple. One of the most common functions is "Fork", which allows developers to copy an existing Git repository and make modifications and commits to the copied repository. This article will introduce you to the Fork function of Git and how to use Git Fork.

1. What is Fork

In Git, Fork means copying an existing GitHub project to your own account, and then operating the project in your own account. Fork operations are very common in collaborative development and can help developers better participate in open source projects. When an open source project is forked, other developers can modify the code in their own fork project, and then submit code contributions to the original project through Pull Request, which not only facilitates personal development, but also contributes more code to the original project.

Fork operations are only performed in the remote warehouse and will not affect your local code base. Each fork project has its own remote warehouse address, which can be found in its own Github warehouse.

2. How to perform Fork operation

1. Open the Github project page that you want to Fork

First, use a browser to open the Github project page that you want to Fork. In the upper right corner of the project page, there will be a "Fork" button. Click it to start the Fork operation.

2. Select the account to be Fork

After clicking the "Fork" button, a selection box will pop up, asking you to select the account to Fork. You can choose to fork into your own repository or fork into an organization's repository, depending on your needs.

3. Wait for the Fork to complete

After selecting the Fork account, Github will start copying the original project to your Github repository. This operation may take several seconds or even minutes to complete.

4. Access your Fork project

When the Fork operation is completed, you can find your newly added Fork project in your Github account. You can click on the project to view its contents, as well as modify and submit it. In this process, all operations are performed in your Fork project and will not affect the original project.

3. How to update Fork projects

In collaborative development, project code is usually forked and updated frequently. If you fork a project and the original project releases a new version, you may want to merge the new version's code into your own fork. Here are two methods to update your Fork project.

1. Update Fork project code

In the Github warehouse page, select the "Pull requests" tab, then click "New pull request", and then you can proceed with the code Merge operation.

2. Rebase the original project

Using Git's rebase operation allows you to merge your Fork code base with the original code base, so that you The code base is kept up to date. The rebase operation is similar to the Merge operation, but it is cleaner and more controllable. For specific operations, please refer to the relevant documentation of Git.

4. Conclusion

Fork is a very important function in Git, which makes collaboration on open source projects easier and more efficient. Through the introduction of this article, I believe that everyone has a deeper understanding of Git's Fork function, and at the same time can better use and apply Git for collaborative development.
