How to do Version Control with Git for DevOps

Part 1: Create Your First Git Repository

Purpose: Learn how Git tracks changes locally — the first step in version control.

Steps

1. Create a folder

   

   You created a project directory to store your code.

2. Initialize Git

   git init

   

   
   

   This turns your folder into a Git repository (Git starts tracking changes here).

3. Create a file

   echo "Hello Git" > hello.txt

   
   

   You made your first file to track.

4. Check the status

   git status

   
   

   Git shows that hello.txt is untracked.

5. Add the file to staging

   git add hello.txt

   

   
   

   This prepares the file for commit (snapshot).

6. Commit your changes

   
   

   git commit -m "Initial commit: added hello.txt"

   

   
   

   Congratulations!!! You’ve saved your first version — a snapshot of the file.

Git records your work in small “commits” that you can track or roll back later.

Part 2: Track File Changes and View History

Purpose: Understand how Git saves different versions of your files.

Steps

1. Edit the file

   echo "This is my second line." >> hello.txt

   
   

2. Check the difference

   git diff

   

   
   

   Shows what changed since the last commit.

3. Stage and commit again

   git add hello.txt

   
   

   git commit -m "Added a second line to hello.txt"

   

4. View commit history

   git log --oneline

   

   See the list of all versions you’ve saved.

   
   

Lesson Learned:Git keeps a complete timeline of your work — you can see, compare, or restore any version anytime.

Part 3: Work with Branches

Purpose: Learn how to work on new features safely without disturbing the main code.

Steps

1. Create and switch to a new branch

   
   

   git checkout -b feature-update

1. Edit the file

   echo "New feature: Git branching!" >> hello.txt

   
   

2. Commit the change

   git add hello.txt

   git commit -m "Added feature update message"

   

   
   

3. Switch back to main branch

   git checkout master

   

   
   

4. Compare branches

   git diff feature-update

Lesson Learned:Branches let you experiment or develop features independently — and merge them later when ready.

Part 4: Merge Changes

Purpose: Understand how to combine your work from multiple branches.

Steps

1. Merge feature branch into main

   git merge feature-update

   Git combines the feature branch changes into main.

   

   
   

2. Check the merged file

   type hello.txt

   

   
   

Part 5: Connect with GitHub and Push Code

Purpose: Learn to upload your local project to GitHub and collaborate online.

Steps

1. Create a new repo on GitHub

   Go to GitHub → “New Repository” → Name it git-demo

   Don’t add README yet.

   
   

2. Connect local Git to GitHub

   git remote add origin https://github.com/<your-username>/git-demo.git

3. Push your code

   git branch -M master

   git push -u origin master

1. Check your GitHub accountYour code is now visible online.

   

   
   

   Lesson Learned:Git + GitHub = version control + cloud collaboration.You can now share your code, work with teams, and track contributions.

How to use Git and Github??

1. Steps to Install Git on Windows 11

Go to the official Git website: https://git-scm.com/downloads

Click “Download for Windows” — it will automatically detect your version.

Run the installer (Git-x.x.x-64-bit.exe).

• Finish and verify installation:

  • Open Command Prompt or VS Code Terminal, and type:

    git --version

  • You should see something like:

    

Step 1: Create a New Repository on GitHub

1. Log in to your GitHub account.

2. Click the + icon in the top-right corner and select "New repository".

3. Enter a Repository name (e.g., my-git-practice).

4. Optionally, add a Description.

5. Choose between Public (visible to anyone) or Private (you control access). For this exercise, either is

fine.

6. Important: Do NOT initialize the repository with a README, .gitignore, or license file yet. We will

create the README locally. Leave these options unchecked.

7. Click the "Create repository" button.

8. On the next page, you'll see instructions and a URL (HTTPS or SSH). Copy the HTTPS URL. It will

look something like https://github.com/your-username/my-git-practice.git.

Step 3: How to use Git and Github and Clone the Repository to Your Local Machine

1. Open your terminal or command prompt.

2. Navigate to the directory where you want to store your project locally using the cd

md my_practice

cd my_practice

3. Use the git clone command followed by the URL you copied in Step 1:

git clone <paste_the_repository_url_here>

Replace <paste_the_repository_url_here> with the actual HTTPS URL. Example:

git clone https://github.com/your-username/my-git-practice.git

4. Git will download the repository (which is currently empty except for hidden Git configuration files)

into a new folder named after your repository (e.g., my-git-practice).

5. Navigate into your new project directory:

cd my-git-practice

Step 3: Create a File and Add it to Staging

1. Inside the my-git-practice directory, create a simple text file named README.md. You can

Windows Command Prompt:

echo # My Git Practice Project >README.md

Change to your repository

2. Now, check the status of your repository:

git status

You should see README.md listed under "Untracked files". This means Git sees the file, but isn't

tracking changes to it yet.

3. Tell Git you want to track this new file and include it in the next snapshot (commit) by adding it to the

git add README.md

Alternatively, you could use git add . to stage all new or modified files in the current directory.

4. Check the status again:

git status

You should now see README.md listed under "Changes to be committed".

Step 4: Commit the Staged Changes

1. Now that the file is staged, commit it to your local repository's history.

Use the git commit

command with the -m flag to provide a descriptive message:

Bash

git commit -m "Add initial README.md file"

o The -m flag allows you to write the commit message inline. If you omit it (git commit),

Git will usually open a text editor for you to write a longer message.

o Good commit messages are crucial! They explain why a change was made.

2. Check the status one more time:

git status

It should now say something like "nothing to commit, working tree clean" and mention that your local

branch is ahead of origin/main (or origin/master).

Step 5: Push the Commit to the Remote Repository

1. Your commit currently only exists on your local machine. To share it with the remote repository

(GitHub/GitLab), use the git push command:

Bash

git push origin main

o origin: This is the default short name Git gives to the remote repository you cloned from.

o main: This is the name of the default branch in most modern Git repositories (historically, it

was often master). If you cloned an older repository or your setup uses master, you might

need to use git push origin master instead. Your git status output in the

previous step might give you a hint about the branch name.

2. You might be prompted to enter your GitHub/GitLab username and password (or a Personal Access

Token, which is more secure and often required now instead of passwords).

3. Once the push is successful, your local commit(s) have been uploaded to the remote repository.

Verification:

 Go back to your repository page on GitHub or GitLab in your web browser.

 Refresh the page.

 You should now see your README.md file listed, along with the commit message you used ("Add

initial README.md file").
