Git Repository Basics

What is a Git Repository?

A Git repository is a digital directory or storage space where your project's files and their entire revision history are stored. Unlike traditional version control systems, Git provides a complete copy of the entire project history on each developer's local machine.

Key Concepts of Git Repositories

Types of Repositories

Repository States

Core Repository Components

1. Working Directory: The actual files you're currently working on
2. Staging Area: Preparation zone for files to be committed
3. Git Directory (Repository): Where Git stores metadata and object database

Creating a Repository

Initialize a New Repository

## Create a new project directory
mkdir my-project
cd my-project

## Initialize a new Git repository
git init

Basic Repository Configuration

## Set global user name and email
git config --global user.name "Your Name"
git config --global user.email "[email protected]"

Repository Best Practices

• Always create a .gitignore file
• Use meaningful commit messages
• Commit frequently
• Keep repositories focused and modular

LabEx Tip

When learning Git repositories, LabEx provides interactive environments that help you practice these concepts in real-world scenarios.

Local Repository Setup

Prerequisites

System Requirements

• Ubuntu 22.04 LTS
• Git installed
• Basic terminal knowledge

Installing Git

## Update package list
sudo apt update

## Install Git
sudo apt install git -y

## Verify installation
git --version

Configuring User Identity

Global Configuration

## Set global username
git config --global user.name "Your Name"

## Set global email
git config --global user.email "[email protected]"

Local Repository Configuration Levels

Creating a Local Repository

Method 1: Initialize New Repository

## Create project directory
mkdir my-project
cd my-project

## Initialize git repository
git init

Method 2: Clone Existing Repository

## Clone repository from remote source

Repository Workflow

Essential Local Repository Commands

## Check repository status

## Add files to staging

## Commit changes

## View commit history

Ignoring Files

Create .gitignore File

## Create .gitignore
touch .gitignore

## Example contents
*.log
node_modules/
build/

LabEx Recommendation

LabEx provides interactive Git environments to practice local repository management with real-world scenarios.

Best Practices

• Commit frequently
• Write descriptive commit messages
• Use branches for different features
• Regularly pull and merge changes

Remote Repository Management

Understanding Remote Repositories

Remote Repository Types

Connecting to Remote Repositories

Adding Remote Repository

## Add remote repository

## View current remotes

Remote Workflow

Essential Remote Commands

Pushing Changes

## Push to main branch
git push origin main

## Push all branches
git push --all origin

Pulling Changes

## Fetch remote changes
git fetch origin

## Pull and merge
git pull origin main

Authentication Methods

SSH Key Setup

## Generate SSH key
ssh-keygen -t rsa -b 4096 -C "[email protected]"

## Copy SSH public key
cat ~/.ssh/id_rsa.pub

Personal Access Tokens

## Generate token in repository platform settings
## Use token for HTTPS authentication

Branch Management

## Create new branch
git branch feature-branch

## Switch to branch
git checkout feature-branch

## Push branch to remote
git push -u origin feature-branch

Collaborative Workflows

Pull Request Process

Resolving Conflicts

## Fetch latest changes
git fetch origin

## Merge and resolve conflicts
git merge origin/main

LabEx Tip

LabEx offers comprehensive remote repository management tutorials and interactive environments for practical learning.

Best Practices

• Always pull before pushing
• Use meaningful branch names
• Communicate with team members
• Review code before merging
• Keep repositories organized

Summary
