Introduction to Git: The Basics You Need to Know – Part 1

What is Git?

Git is a distributed version control system that revolutionized the way developers work on projects. Unlike older centralized version control systems, Git gives every developer a full copy of the entire history of the project, enabling more flexible workflows and safer handling of projects. This decentralization makes it incredibly powerful for collaborative software development.

Why Should You Learn Git?

• History Tracking: Every change made to your project is recorded, so you can return to previous versions at any time.
• Branching and Merging: Create separate branches for new features, making it easy to try out ideas without affecting the main project.
• Staging Area: Decide exactly which changes you want to include in your next commit, allowing for precise control over your project’s history.
• Collaboration: Easily collaborate with others by pulling in their changes into your project and pushing your changes to them.

Installing Git

To get started, you need to install Git:

• Windows: Download and run the Git installer from Git’s official website.
• Mac: If you have Homebrew installed, simply type brew install git in the terminal. Otherwise, download the installer from the Git website.
• Linux: Use your distribution’s package manager, such as sudo apt install git on Debian-based systems, or sudo yum install git on Fedora.

Configuring Git

After installation, configure your identity:

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

These settings are crucial as they are included in the commits you make, identifying you as the author.

Creating Your First Git Repository

To start your project, set up a new repository:

mkdir my-first-git-project
cd my-first-git-project
git init

This series of commands creates a new directory and initializes it as a Git repository.

Essential Git Commands

• git status: Shows the current state of the repository including staged, unstaged, and untracked files.
• git add [file-name]: Adds specific files to the staging area in preparation for a commit.
• git commit -m "[description]": Records your changes officially in the repository history.
• git log: Displays the detailed log of commits, including author, date, and commit message.
