Find Branches Not Containing a Commit (Challenge)

Introduction

Git is a popular version control system that allows developers to track changes in their codebase. One of the useful features of Git is the ability to create branches, which are essentially separate copies of the codebase that can be modified independently. However, sometimes it can be difficult to keep track of which branches contain certain commits. In this challenge, you will learn how to find branches that do not contain a specific commit.

Find Branches Not Containing a Commit

You are working on a project with multiple branches, and you need to find all the branches that do not contain a specific commit. This can be useful if you want to make sure that a certain change has been applied to all branches, or if you want to know which branches are outdated and need to be updated.

Tasks

For this challenge, we will be using the Git repository named https://github.com/your-username/git-playground.

1. Clone this repository to your local machine.
2. Once you have cloned the repository, navigate to the directory.
3. Create and switch to a new-branch branch and make some code changes on that branch and then commit it, the commit message is "Create a new-branch branch".
4. Check the hash of the commit message "Create a new-branch branch".
5. Finds all branches that do not contain a hash with the commit message "Create a new-branch branch".

This will output a list of all the branches that do not contain the specified commit. In this case, the output will be:

master

This means that the master branch do not contain the commit with the hash 31c5ac20129151af1.

Summary

In this challenge, you learned how to find branches that do not contain a specific commit using the git branch --no-contains command. This can be useful for keeping track of which branches have been updated and which ones need to be updated.
