Git and GitHub: Understanding Version Control

#git #github

What is Version Control?
Version Control, also known as Source Control, is a system that helps you manage code efficiently.

version control allows you to:
> Track your files
> Revert your files to previous versions

CVCS vs DVCS:
There are two main types of version control systems:

 > CVCS – Centralized Version Control System
 > DVCS – Distributed Version Control System

Git is based on DVCS, meaning every developer has a local copy.

Git Advantage:
> Works with a local copy of the repository and commit changes locally.

Git Lifecycle: The Three States
A file in Git can be in one of three states:

  1. Modified – The file has been changed but not yet tracked.
  2. Staged – The changes are marked for the next commit (like a temporary area before committing).
  3. Committed – The changes are saved in your local Git database.

Steps to Commit:

Step 1: Add the files
git add

Step 2: Commit the changes with a message
git commit -m "your commit message"

Step 3: Push changes to the repository
git push origin

Create a Local Git Repository:

git init
git add ML.txt
git commit -m "Added Personal Details"

git status
git log

Creating a Personal Repository on GitHub:

Step 1: Go to GitHub
Step 2: Click on New Repository
Step 3: Name your repository
Step 4: Add Description
Step 5: Choose visibility (public/private)
Step 6: Click Create repository

git config --global user.username "harinimadura06"
git config --global user.email "harinimadura06@gmail.com"

git remote add origin https://github.com/harinimadura06/24MCR030.git
git branch -M main
git push -u origin main

git branch
