How to change the branch name in git? Brief analysis of methods

When using Git for multi-person collaborative development, a project usually has multiple branches. These branches can be used to add new features, fix bugs, or perform other types of development tasks. Sometimes, we need to modify the branch name to reflect the current development tasks or status changes. This article will introduce how to use Git commands to change the branch name.

View branches

Before you start changing the branch name, you need to check the currently available branches. You can view local branches through the following command:

git branch

This command will return a list of all local branches, and use * to indicate the current branch. If you want to view remote branches, you can use the following command:

git branch -r

This command will return a list of remote branches. It is worth noting that the name of the remote branch will be preceded by the name of the remote server and a backslash.

Create a new branch

If you want to create a new branch, you can use the following command:

git branch <new_branch_name></new_branch_name>

This will create a new branch on the current branch. The new branch will fork from the current branch and inherit all its commit records. You can use the following command to work on a new branch:

git checkout <new_branch_name></new_branch_name>

This will switch the Git branch to the newly created branch.

Change the branch name

Changing the branch name is a relatively simple task. You can use the following command to change the branch name:

git branch -m <new_branch_name></new_branch_name>

This command will change the name of the current branch to the new branch name.

If you want to change the name of another branch, you need to switch to that branch first. The following command can be used:

git checkout <old_branch_name></old_branch_name>

The branch name can then be changed using the following command:

git branch -m <new_branch_name></new_branch_name>

This will change the name of the selected branch.

Push changes

The last step is to push the changes to the remote repository. Changes can be pushed to the remote repository using the following command:

git push origin -u <new_branch_name></new_branch_name>

This command pushes the newly created branch into the Git repository and associates it to the remote branch. If you change the name of an existing branch, you need to execute the following command:

git push origin -u <new_branch_name> --force</new_branch_name>

Note that you must use the --force flag when changing the name of an existing branch, otherwise Git will throw an error.

Summary

In multi-person collaborative development, Git branches can help with independent development and management of code. This article explains how to create, view, and change branch names and push changes to remote repositories. With these simple Git commands, you can easily manage and control branches of your Git project.
