Step 2 - To check status git status - Create a File and Make Your First Commit Step 1 - Do this in Git Bash: echo "Hello Git!" ＞ hello.txt git status Step 2 - Stage the file git add hello.txt Step 3 - Commit the file git commit -m "my first commit: Added hello.txt" 🔍 What just happened: git add: stages the file (prepares it for commit) git commit: saves it to Git history with a message Step 4 - Check commit log git log - Modify the File and Track Changes Step 1 - Open hello.txt in any editor (Notepad, VS Code, etc.) Step 2 - Make some change. Save and close Step 3 - Check status git status Step 4 - View the change git diff This shows the exact line added Step 5 - Stage and commit git add hello.txt git commit -m "Updated hello.txt with second line" We’ve now made a second commit! - View Commit History and File Versions Step 1 - View commit history git log --oneline Shows each commit in one line (handy summary) Step 2 - See previous version of the file git show HEAD~1:hello.txt HEAD~1 means: "One commit before the current one" :hello.txt shows how the file looked in that commit. Step 3 - See what changed between commits: git diff HEAD~1 HEAD will see the exact difference between the last two versions - Create and Switch Branches Step 1 - Create a new branch: git branch feature-1 Step 2 - Switch to that branch: git checkout feature-1 Step 3 - Make some change in hello.txt Step 4 - Stage and commit git add hello.txt git commit -m "Add feature line in hello.txt" Step 5 - View all branches git branch - Merge Branches Step 1 - Switch to main branch git checkout master Step 2 - Merge the feature branch git merge feature-1 Step 3 - (Optional): Delete the feature branch git branch -d feature-1 We've now completed a full branching + merging cycle - Create a GitHub Repo and Push Your Code Step 1 - Go to https://github.com and sign up or log in Step 2 - Create a new repository Step 3 - Push local repo to GitHub git remote add origin https://github.com/YOUR_USERNAME/git-demo.git git branch -M main git push -u origin main remote add origin: connects your local repo to GitHub. push -u origin main: uploads your code to the main branch. Step 4 - Go to GitHub and refresh — our code is now online - Clone a Repository from GitHub Step 1 - Copy your repo link Step 2 - Run git clone https://github.com/your-username/git-demo.git Downloads the entire repo Keeps full commit history and branches Step 3 - Check the cloned project folder ✅ we now have a fresh copy of your project from GitHub - ▬▬▬▬▬▬▬ Share with all who may need this If my work has helped you, consider helping any animal near you, in any way you can Never Stop Learning Raghav Pal ▬▬▬▬ USEFUL LINKS ▬▬▬▬ ✅ ALL TUTORIALS - https://AutomationStepByStep.com/ ---
