Git Repository Basics

Understanding Git Version Control

Git is a distributed version control system designed to track changes in source code during software development. It enables multiple developers to collaborate efficiently by managing code modifications, branching, and merging.

Key Concepts of Git Repositories

Git repositories are storage spaces for project files and their complete version history. They can be local or remote, providing a comprehensive tracking mechanism for software development.

Repository Types and Initialization

Repository Type	Description	Initialization Command
Local Repository	Personal project space	`git init`
Remote Repository	Shared project space	`git clone <repository-url>`

Creating a Git Repository in Ubuntu 22.04

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

## Initialize a new Git repository
git init

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

## Create initial project files
touch README.md
echo "## My Project" > README.md

## Stage and commit initial files
git add README.md
git commit -m "Initial project setup"

Basic Git Operations

Fundamental git operations include staging files, committing changes, and checking repository status:

## Check repository status
git status

## Stage specific files
git add filename.txt

## Stage all changes
git add .

## Commit changes with message
git commit -m "Descriptive commit message"

Repository State and Tracking

Git tracks file states through three main areas: working directory, staging area, and repository. Understanding these helps manage code effectively in version control workflows.

Repository Path Management

Understanding Repository Paths

Repository path management involves navigating and configuring Git repository locations, ensuring efficient code organization and version control across different directories.

Git Path Management Commands

Command	Function	Usage
`pwd`	Print current directory	Verify current location
`cd`	Change directory	Navigate repository paths
`git rev-parse --show-toplevel`	Show repository root	Locate repository base

Practical Path Management in Ubuntu 22.04

## Create project structure
mkdir -p ~/projects/web-app
cd ~/projects/web-app

## Initialize Git repository
git init

## Check current repository path
pwd
## Output: /home/username/projects/web-app

## Verify repository root
git rev-parse --show-toplevel
## Output: /home/username/projects/web-app

## Move to parent directory
cd ..

## Clone repository to specific path
git clone  custom-project-name

Repository Configuration and Path Settings

## Set repository-specific configuration
git config --local core.worktree /path/to/custom/location

## Check current repository configuration
git config --list --show-origin

Path Manipulation Techniques

## List all tracked files with their paths
git ls-files

## Find files matching specific path pattern
git ls-files | grep "src/"

Advanced Git Operations

Remote Repository Management

Remote repositories enable collaborative development and code synchronization across distributed teams.

Remote Repository Operations

Operation	Command	Description
Add Remote	`git remote add`	Connect local repository to remote
List Remotes	`git remote -v`	Display configured remote repositories
Push Changes	`git push`	Upload local commits to remote
Fetch Updates	`git fetch`	Download remote changes

Advanced Remote Synchronization

## Add remote repository
git remote add origin 

## Push all branches to remote
git push --all origin

## Fetch and merge remote changes
git fetch origin
git merge origin/main

## Rebase local changes on top of remote
git pull --rebase origin main

Branch Management and Workflow

## Create and switch to new branch
git checkout -b feature/new-component

## List all branches
git branch -a

## Merge branches
git checkout main
git merge feature/new-component

Advanced Commit Management

## Interactive rebase
git rebase -i HEAD~3

## Squash multiple commits
git rebase -i HEAD~4

## Amend last commit
git commit --amend

Conflict Resolution Strategies

## Resolve merge conflicts
git mergetool

## Abort merge process
git merge --abort

Summary

By mastering Git repository basics, developers can efficiently track code changes, manage project versions, and collaborate seamlessly. The tutorial demonstrates critical skills like repository initialization, file staging, committing changes, and understanding Git's core version control mechanisms, empowering programmers to leverage Git's powerful distributed version control capabilities.
