Master Git Commands: A Beginner's Guide 🚀

If you want to become a professional developer, learning **Git** is mandatory. It is the tool that saves your code history and helps teams work together. In this guide, we will look at the most important Git commands you need for daily work. No complex theory, just practical commands!

1. How to Start a Project? (The Start)

If a project already exists on the internet (GitHub), you need to download it to your computer.

git clone [url]

This command downloads the entire project code from the cloud to your local machine.

git clone https://github.com/username/projectname.git

It creates a new folder with the project name.

2. How to Save Your Code? (The Save Cycle)

Saving in Git is a two-step process. First, you choose the files, and then you "Commit" (Save) them.

Step A: Staging (Select Files)

Tell Git which files you want to prepare for saving.

1. To select a specific file:

git add index.php

2. To select ALL changed files (Recommended):

git add .

Note: The dot `.` means "Everything".

Step B: Commit (Final Save)

This permanently saves your changes with a message.

git commit -m "Designed the login page"

Always write a clear message inside the quotes `""`.

3. Syncing with the Cloud

How to send your code to GitHub or get updates from your team.

Command	Description
`git push origin main`	Upload: Sends your saved code (commits) from your computer to the GitHub server.
`git pull origin main`	Download/Update: If your team member updated the code, use this command to download their changes to your computer.

4. Branching (Parallel Universes) 🌿

A "Branch" is like a parallel copy of your code. You create a branch to work on new features so you don't break the main website.

Useful Branch Commands:

1. To see all branches:

git branch

2. To create a new branch:

git branch login-page-design

3. To switch to another branch:

git checkout login-page-design

Now, whatever code you write will stay in this branch only.

4. To go back to the main code:

git checkout main

⚡ Quick Cheat Sheet
