How to change the name of a branch in Git

In the process of using Git for development, we often need to operate branches, and modifying the name of a branch is a common operation. Next, we will introduce how to modify the name of the branch in Git.

1. View the branch

Before modifying the name of the branch, we first need to view the currently existing branch through the git branch command to confirm which branch we need to modify name. You can use the following command to view branches:

$ git branch
  master
* develop
  feature-A
  feature-B

The above command will list all current local branches and use * to identify the current branch (in the above example, the current branch is develop branch).

2. Rename the branch

After determining the branch that needs to be modified, we can use the git branch -m command to modify the branch name. The syntax of this command is:

$ git branch -m oldbranch newbranch

where oldbranch is the original name of the branch to be modified, and newbranch is the new name of the branch to be modified.

For example, if we need to rename the branch named feature-A to feature-C, we can use the following command:

$ git branch -m feature-A feature-C

3. Push the modified branch

After modifying the local branch name, we need to push the modified branch to the remote warehouse. You can use the following command to push the modified branch to the remote warehouse:

$ git push origin :oldbranch newbranch

where oldbranch is the original name of the branch to be modified, and newbranch is the new name of the branch to be modified.

For example, if we need to rename the branch named feature-A to feature-C and push the modified branch to the remote warehouse, we can use the following command:

$ git push origin :feature-A feature-C

4. Delete the branch with the old name

If we don’t need to keep the branch with the old name, we can use the following command to delete it:

$ git push origin :oldbranch

The above are the steps to use Git to modify the branch name. Of course, before use Please consider carefully to avoid misoperation.
