Overview

On this page, we describe how to create new branches with Git.

Creating branches

There are several ways that you can create new branches with Git.

Use Git Gui to create a new branch

1. Start git gui

git gui &

2. Go to the Branch/Create on the menu bar (or type CTRL-N).

3. A dialog box will pop up. Type the name of the new branch that you wish to create. Your new branch name should adhere to the Gitflow nomenclature.

Git will automatically check out the new branch that you just created.

Use Gitk to create a new branch

You can also create a new branch very quickly from the Gitk browser.

1. Start gitk

gitk --all &

2. Move your mouse to the name of the commit from which you would like to create a new branch. Right-click on the name of that commit. This will pop open a context menu.

4. Type the name for your branch and click on Create. Your new branch name should adhere to the Gitflow nomenclature.

Git will automatically check out the new branch that you just created.

Create a new branch from the command line

First, check out the branch that you wish to branch off from. In this case, let's branch off master.

git checkout master

If you are creating a new feature branch, then type:

git branch feature/NAME
git checkout feature/NAME

On the other hand, if you are creating a bugfix branch, then type:

git branch bugfix/NAME
git checkout bugfix/NAME

where NAME is to be the name of the feature or bug fix that you are implementing.

3. Click on Check out this branch.

Check out a branches from the command line

To switch from the currently checked-out branch to a different branch, type:

git checkout BRANCH-NAME

Determining which branch is checked out

You can determine which branch is currently checked-out as follows:

Using this: Follow these steps:
Git GUI Look at the top left (under the Repository menu), and you will see the name the branch that is currently checked-out.
Gitk Look for the GREEN BOX with the boldfaced name inside. This indicates the branch that is currently checked-out.
The command line Type:
git branch

and you will see all of the branches:

 dev/12.4.0
*master

The branch that is currently checked-out will have an * in front of it.

Deleting branches
