Git Basics

What is Git?

Git is a powerful distributed version control system designed for tracking source code changes during software development. As a critical tool in modern software engineering, Git enables developers to manage and collaborate on projects efficiently.

Core Concepts of Version Control

Git operates on several fundamental principles:

Concept	Description
Repository	A directory containing project files and Git metadata
Commit	A snapshot of project changes at a specific point in time
Branch	An independent line of development
Remote	A shared version of the repository hosted on a server

Git Architecture

Installation and Configuration

To install Git on Ubuntu 22.04, use the following commands:

sudo apt update
sudo apt install git
git --version

Configure your identity:

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

Basic Git Commands

Initialize a new repository:

mkdir my-project
cd my-project
git init

Stage and commit changes:

git add .
git commit -m "Initial project setup"

Check repository status:

git status
git log

These commands demonstrate Git's core functionality in managing source code and tracking project evolution across distributed systems.

Repository Operations

Creating and Initializing Repositories

Git repositories can be created through two primary methods:

## Method 1: Initialize a new repository
git init my-project

## Method 2: Clone an existing repository
git clone

Staging and Committing Changes

The Git workflow involves three key stages:

Staging and committing process:

## Add specific files
git add file1.txt file2.py

## Add all changes
git add .

## Commit with descriptive message
git commit -m "Implement feature X"

Version Tracking Operations

Key repository management commands:

Command	Function
git status	Check current repository state
git log	View commit history
git diff	Compare file changes
git restore	Revert uncommitted changes

Advanced Repository Management

Handling complex repository operations:

## Remove files from tracking
git rm file.txt

## Move or rename files
git mv oldname.txt newname.txt

## Ignore files using .gitignore
echo "*.log" >> .gitignore

These operations enable precise control over source code version tracking and management in distributed development environments.

Collaborative Development

Remote Repository Interactions

Remote repositories enable distributed team collaboration:

## Add remote repository
git remote add origin 

## List remote repositories
git remote -v

Branch Management Workflow

graph LR A[Main Branch] --> B[Feature Branch] B --> C[Pull Request] C --> D[Code Review] D --> E[Merge]

Branch creation and switching:

## Create new branch
git branch feature-login

## Switch to branch
git checkout feature-login

## Create and switch in one command
git checkout -b feature-authentication

Synchronization Commands

Command	Function
git push	Upload local commits to remote
git pull	Download and merge remote changes
git fetch	Download remote changes without merging

Merge Strategies

Handling code integration:

## Merge branches
git merge feature-branch

## Rebase branches
git rebase main

## Resolve merge conflicts
git mergetool

Collaborative Workflow Example

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

## Create pull request
git request-pull main origin/feature-branch

These techniques facilitate seamless code collaboration across distributed development teams.

Summary

By understanding Git's core concepts, repository operations, and collaborative development techniques, developers can streamline their workflow, enhance code management, and improve team productivity in modern software engineering environments.
