Git Version Control Basics
Understanding Version Control Systems
Version control systems (VCS) are essential tools in modern software development, enabling developers to track and manage code changes efficiently. Git, a distributed version control system, revolutionizes how teams collaborate and manage software projects.
Core Concepts of Git
Git provides powerful mechanisms for tracking code modifications, maintaining project history, and facilitating collaborative development. Key fundamental concepts include:
Concept |
Description |
Repository |
Central storage for project files and version history |
Commit |
Snapshot of project changes at a specific point in time |
Branch |
Parallel development line for independent feature work |
Staging Area |
Intermediate zone for preparing changes before committing |
Basic Git Configuration
## Set global user name
git config --global user.name "Your Name"
## Set global email address
git config --global user.email "[email protected]"
## Verify configuration
git config --list

Initializing a Git Repository
## Create new project directory
mkdir my-project
cd my-project
## Initialize git repository
git init
## Create initial README file
touch README.md
## Stage and commit initial files
git add README.md
git commit -m "Initial project setup"
Key Git Commands for Version Control
## Check repository status
git status
## View commit history
git log
## Create a new branch
git branch feature-branch
## Switch to a branch
git checkout feature-branch
The Git version control system empowers developers to manage code effectively, track changes, and collaborate seamlessly across distributed teams.
