How to change the branch name in git

Git is an excellent version control tool that plays an important role in team collaboration and personal development. In Git, branching is a very important concept. Each branch is equivalent to an independent code tree, on which the code of other branches can be independently developed or merged. In the actual development process, we often need to change the branch name to adapt to the needs of the project or a more standardized naming method. This article will introduce in detail how to change the branch name in Git.

1. View existing branches

Enter the directory of the Git project on the command line and view the currently available branches through the following command:

git branch

This This command will list all existing branches in the current project, with an asterisk in front of the current branch. As shown below:

$ git branch
* main
  feature-1
  feature-2
  develop

As can be seen from the above example, the current branch is "main", and the other three branches are "feature-1", "feature-2" and "develop".

2. Change branch name

Assume that we now need to change the "feature-1" branch to "login", which can be achieved using the following command:

git branch -m feature-1 login

Among them, "-m" means move branch, followed by the original branch name "feature-1" and the new branch name "login".

We can check the branch list again through the "git branch" command to confirm that the branch name has been changed successfully:

$ git branch
  main
  login
  feature-2
  develop

3. Push the changed branch name

After changing the branch name locally, the changes need to be synchronized to the remote warehouse for collaborative development by others. You can use the following command to push the changed local branch "login" to the remote warehouse:

git push origin login

where "origin" is the default name of the remote warehouse, or it can be another custom name. After executing the above command, others can pull the "login" branch locally for collaborative development.

4. Notes

When changing the branch name, there are some things to pay attention to:

• Make sure that before changing the branch name, The code on this branch has been submitted to the warehouse to avoid code loss;
• If the branch you are working on is the branch that needs to be changed, you need to switch to another branch first and then change the name;
• After the branch name is changed, all commit history will be retained, and the history can be viewed by the new name or the old name.

To sum up, changing the branch name using Git is very simple and can be easily achieved through the above commands. In actual development, branches need to be reasonably planned and managed according to project requirements to ensure code reliability and development efficiency.
