How to Create a Git Branch from Another Branch Easily

To create a new branch from another branch in Git, first switch to the source branch using git checkout source-branch, then create and switch to the new branch with git checkout -b new-branch. This makes the new branch start from the current state of the source branch.

Syntax

The process involves two main commands:

• git checkout source-branch: Switches your working directory to the branch you want to base your new branch on.
• git checkout -b new-branch: Creates a new branch named new-branch starting from the current branch and switches to it immediately.

bash

git checkout source-branch
git checkout -b new-branch

Example

This example shows how to create a branch named feature from an existing branch called develop. It first switches to develop, then creates and switches to feature.

bash

$ git checkout develop
Switched to branch 'develop'
$ git checkout -b feature
Switched to a new branch 'feature'

Output

Switched to branch 'develop'
Switched to a new branch 'feature'

Common Pitfalls

One common mistake is creating a new branch without switching to the source branch first, which causes the new branch to start from the current branch instead of the intended one.

Wrong way:

git checkout -b new-branch source-branch

This command works and switches to the new branch starting from source-branch, but it does not switch to source-branch first, which can confuse beginners about the current branch context.

Right way:

git checkout source-branch
git checkout -b new-branch

This ensures you are on the correct base branch before creating the new one.

bash

git checkout -b new-branch source-branch
# This creates new-branch from source-branch and switches to it immediately

# Recommended approach:
git checkout source-branch
git checkout -b new-branch

Quick Reference

Command	Description
git checkout source-branch	Switch to the branch you want to base your new branch on
git checkout -b new-branch	Create and switch to a new branch from the current branch
git branch new-branch source-branch	Create a new branch from source-branch without switching to it
git switch -c new-branch source-branch	Create and switch to a new branch from source-branch (modern alternative)

Key Takeaways

Always switch to the source branch before creating a new branch to ensure correct starting point.

Use git checkout -b new-branch to create and switch to the new branch in one step.

You can create a branch from another branch without switching using git branch new-branch source-branch.

The modern alternative to git checkout is git switch -c new-branch source-branch.

Check your current branch with git status to avoid confusion before creating branches.
