How do i get the current branch name in git?

shell
 git branch

This command displays all local branches of your repository. The branch marked with an asterisk is your current branch.

---

To retrieve only the name of your current branch:

shell
 git rev-parse --abbrev-ref HEAD

Version 2.22 introduced the "Print current branch name" --show-current option. This command also works for repositories initialized before the first commit: link

shell
 git branch --show-current

Several methods exist in Git to retrieve the current branch name. This article introduces two commonly used approaches:

1. Using the git branch command

When running the git branch command, it lists all branches in the repository. The current branch is marked with an asterisk (*) in the list. For example:

bash
$ git branch
  main
* develop
  feature-xyz

In this example, the current branch is develop.

2. Using the git rev-parse command

If you need to use this in scripts or directly obtain the current branch name, you can use the git rev-parse command. This method directly outputs the current branch name without displaying other branch information. The command is:

bash
$ git rev-parse --abbrev-ref HEAD

This command outputs the current branch name. For example, if the current branch is develop, the output will be:

shell
develop

This method is well-suited for automation scripts as it directly returns the branch name without additional information.

Example Usage Scenario

Suppose I am working on a software development project that uses Git for version control. I need to ensure I am developing the new user interface feature on the feature-new-ui branch. To verify my current working environment, I can use the following command:

bash
$ git rev-parse --abbrev-ref HEAD

If the returned branch name is feature-new-ui, I can proceed with my development task confidently; otherwise, I need to switch to the correct branch.

Using such commands effectively avoids developing on the wrong branch, reducing potential merge conflicts or errors in the future.
