Git Branch

In Git, a branch represents an independent line of development. Branches serve as an abstraction for the edit/stage/commit process in Git. They are a pointer to a specific commit in the repository and move forward as new commits are created.

The main purpose of branching is to allow developers to isolate their work from others, making it easier to manage and coordinate changes to shared repositories. This makes branches particularly useful in a team setting, where several developers are working concurrently on different features or fixes.

Creating and Switching Branches with Git​

Creating and switching branches in Git allows you to work on different features or fixes in parallel without affecting the main codebase. In this tutorial, we'll guide you through the process of creating and switching branches with Git.

To create a new branch, you use the command git branch <branch-name>, and to switch to an existing branch, you use git checkout <branch-name>. If you want to create a new branch and switch to it in one command, you can use git checkout -b <branch-name>.

Step 1: Open a Terminal​

First, open a terminal on your system. If you're on Windows, you can use Git Bash which was installed with Git.

Step 2: Navigate to Your Git Repository​

Use the cd(change directory) command to navigate to your Git repository. For example, if your repository is located in a folder named "my_project" on your desktop, you would use the following command:

cd Desktop/my_project

Step 3: Create a New Branch​

To create a new branch, you use the git branch command followed by the name of the branch. For example, to create a branch named "feature", you would use the following command:

git branch feature

Step 4: Switch to the New Branch​

To switch to the new branch, you use the git checkout command followed by the name of the branch. For example, to switch to the "feature" branch, you would use the following command:

git checkout feature

In newer versions of Git, you can create a new branch and switch to it in one command using the -b option with the git checkout command:

git checkout -b feature

Merging Branches with Git​

Merging branches in Git allows you to integrate changes from one branch into another. This is often done to combine features or fixes developed in parallel on different branches. In this tutorial, we'll guide you through the process of merging branches with Git.

Step 1: Open a Terminal​

First, open a terminal on your system. If you're on Windows, you can use Git Bash which was installed with Git.

Step 2: Navigate to Your Git Repository​

Use the cd(change directory) command to navigate to your Git repository. For example, if your repository is located in a folder named "my_project" on your desktop, you would use the following command:

cd Desktop/my_project

Step 3: Switch to the Branch You Want to Merge Into​

Before merging, you need to switch to the branch that you want to merge into. For example, if you want to merge changes into the "master" branch, you would first need to switch to the "master" branch:

git checkout master

Step 4: Merge the Branch​

To merge a branch, you use the git merge command followed by the name of the branch you want to merge. For example, to merge a branch named "feature" into the "master" branch, you would use the following command:

git merge feature

This command will integrate the changes from the "feature" branch into the "master" branch.

Deleting Branches with Git​

Deleting branches in Git allows you to clean up your repository by removing branches that you no longer need. This can be especially helpful in large projects with many branches. In this tutorial, we'll guide you through the process of deleting branches with Git.

Step 1: Open a Terminal​

First, open a terminal on your system. If you're on Windows, you can use Git Bash which was installed with Git.

Step 2: Navigate to Your Git Repository​

Use the cd(change directory) command to navigate to your Git repository. For example, if your repository is located in a folder named "my_project" on your desktop, you would use the following command:

cd Desktop/my_project

Step 3: Check Current Branches​

Before deleting a branch, it's a good idea to check which branches currently exist in your repository. You can do this using the git branch command:

git branch

This command will list all of the branches in your repository. The current branch will be highlighted and marked with an asterisk.

Step 4: Delete the Branch​

To delete a branch, you use the git branch command followed by -d(for delete) and the name of the branch. For example, to delete a branch named "feature", you would use the following command:

git branch -d feature

If the branch has not been merged and you still want to delete it, you can use the -D option instead:

git branch -D feature

Conclusion​

Congratulations! You've successfully created and switched branches with Git, merged branches with Git, deleted a branch with Git. Branching is a powerful feature of Git that allows you to work on different features or fixes in parallel, safely experiment with new ideas, and merge changes when they're ready.
