How to delete the master branch in git

Git is a version control system generally used for code management and team collaboration. Normally, when we create a Git repository, we will create a master branch named master by default. This branch is often used to store the latest code version of the project. However, in some cases we may need to delete this branch. This article will introduce how to delete the master branch.

What is the master branch

In Git, branching is a way to separate the code warehouse into different lines of development. Typically, the initial code is developed on the master branch. The master branch is considered the "main branch" of the repository because it is the central and default branch of the repository. All other branches are derived from this branch.

The master branch usually contains the latest code version and is considered stable. Because it is the default branch, you can use the git checkout command without specifying a branch name to switch to this branch and start any new changes or commits.

Delete the master branch

We know that the master branch is the default branch, so if we want to delete it, we need to create a new branch to take over the master branch code. This branch can be based on the code on the master branch and is implemented as follows:

1. View existing branches

In the Git warehouse, you can use the following command to view the existing branches in the warehouse List of existing branches:

$ git branch

This command will list all existing branches. Here you can confirm whether there are other branches that should be in this repository.

2. Create a new branch

When creating a new branch, it is best to use the git branch command and -b option, this will create a new branch and switch to the current workspace on that new branch:

$ git branch new-branch
$ git checkout new-branch

These commands do the following:

• Create a new branch named new -branch's new branch
• Switch to the newly created new-branch branch

3. Delete the master branch

When the new branch is created And when you have switched to a new branch, you can use the following command to delete the existing master branch:

$ git branch -D master

This will delete the master branch from the Git repository. Its code will be retained on the newly created branch, so that you can modify, push or merge the new branch at will.

Best Practice

In Git, deleting the master branch is not a good practice. The reasons are as follows:

• The master branch is the default branch of Git, and changing it will cause confusion in the Git workflow.
• If there are multiple developers working in the same warehouse, deleting the master branch may affect their synchronization and collaboration.
• Deleting the master branch may affect integration with continuous integration, automated testing, and other tools.

So, before deleting the master branch, please make sure you have considered these factors and are sure you need to proceed with deleting it.

Summary

This article mainly introduces the methods and best practices for deleting the master branch in Git. Deleting the master branch is not a good idea as it can cause a lot of problems and have an impact on team collaboration and code version control. Nonetheless, at some point it is purely necessary to delete the master branch, and at this time we should use the above method to ensure that the code continues to be saved in the Git repository.

When using Git branches, it’s important to remember: branches are your tools for exploration and experimentation. Only by using appropriate workflows and using branches to manage your projects and code can you take full advantage of Git.
