Why Learn Git?

If you’re writing code, Git is your best friend. It’s like having a time machine for your code - you can save different versions, go back in time if something breaks, and collaborate with others seamlessly. Let me show you how I use Git every day and why it’s simpler than you might think.

Getting Started with Git

Think of Git like taking snapshots of your code. Each snapshot (commit) saves your progress, and you can always return to it later. Here’s what you need to know:

Basic Commands You’ll Use Daily

# Check what files have changed
git status

# Save your changes
git add .
git commit -m "Add new feature"

# Share your changes
git push

# Get latest changes
git pull

Creating Your First Repository

  1. Make a new folder for your project

  2. Open terminal in that folder

  3. Run these commands:

    git init
echo "# My Project" > README.md
git add README.md
git commit -m "First commit"

Working with Branches

Branches let you work on new features without affecting the main code. It’s like having a separate workspace:

# Create a new branch
git checkout -b feature-login

# Switch between branches
git checkout main

Common Scenarios

Scenario 1: Saving Your Work

When you’ve made changes you want to keep:

git add .
git commit -m "Add login form"
git push

Scenario 2: Getting Team Changes

Before starting new work:

git pull

Scenario 3: Starting a New Feature

git checkout -b new-feature
# Make your changes
git add .
git commit -m "Add new feature"

Tips I Wish I Knew Earlier

  1. Commit Often: Small, regular commits are better than big, rare ones
  2. Write Clear Messages: Future you will thank present you
  3. Pull Before Push: Always get the latest changes first
  4. Use Branches: Keep your work separate and organized

Quick Reference Guide

Save this for later:

What You WantCommand to Use
Check statusgit status
Save changesgit add . then git commit -m "message"
Get updatesgit pull
Share codegit push
New branchgit checkout -b branch-name

Next Steps

Start small:

  1. Create a test repository
  2. Make some changes
  3. Commit them
  4. Create a branch
  5. Make more changes

Remember: Git becomes easier with practice. Don’t worry about memorizing commands - focus on understanding the basic workflow, and the rest will come naturally.
