Objective

• Creating branches
• Merging changes
• Managing branches in Git

Prerequisites

• A GitHub account.
• Git installed on your local machine.

Steps

1. Fork the Repository

• From this GitHub repository.
• Click on "Fork" above to create a copy in your GitHub account.

2. Clone the Forked Repository

Clone the forked repository to your local machine:

git clone [URL of your forked repository]

Replace [URL of your forked repository] with the actual URL of your fork.

3. Create and Work on Branch A

Navigate to your repository:

cd [repository name]

Check the current branch using the command below (should be main):

git branch

Create and switch to branch A:

git checkout -b branch-a

Confirm you are on branch A:

git branch

Add a text file to this repo named feature1.txt

touch feature1.txt

Open the text file and add "feature 1" to the feature1.txt file. Example command below:

open feature1.txt

Add the text "feature 1" to the file, save and close the editor.

Go back to your terminal and check the status of your git:

git status

Add and commit the change:

git add feature1.txt
git commit -m "Add feature 1"

4. Create and Work on Branch B

Switch to the main branch and check the current branch:

git checkout main
git branch
ls and enter

Create and switch to branch B:

git checkout -b branch-b
git branch

Add a text file to the current branch, branch-b, of this repo named feature1.txt

touch feature1.txt

Manually open the text file and add "feature 2":

open feature2.txt

Add the text "feature 2" to the file, save and close the editor.

Add and commit the change:

git add feature2.txt
git commit -m "Add feature 2"

5. Merge Branch B into Branch A

Switch to branch A and merge branch B into it:

git checkout branch-a
git merge branch-b

Resolve any conflicts if they arise and commit the changes.

6. Merge Branch A into Main

Switch to the main branch:

git checkout main
git merge branch-a

7. Delete Feature Branches

Delete branches A and B locally:

git branch -d branch-a
git branch -d branch-b

8. Push Main Branch and Create a Pull Request

Push the main branch to your forked repository:

git push origin main

9. Title Pull Request

On GitHub, navigate to your forked repository and create a pull request to the original repository. Title your PR "Merge branch-b into branch-a: Add both files."
