Mastering Git: 4 Zones and Essential Commands

POST 3 of 10 — Core Concepts (The Mental Model) This mental model is what finally made Git click for me. Most people jump straight into commands without understanding what’s actually happening. Don’t be that person. Git has 4 zones — and files move through them in order: Working Directory → Staging Area → Local Repository → GitHub (your files) → (git add) → (git commit) → (git push) Think of Git like mailing a package 📦 📁 Working Directory — items on your desk 🎯 Staging Area — items placed in the box (git add) 💾 Commit — the sealed box with a label (your message) ☁️ Push — shipping the box to GitHub’s warehouse POST 4 of 10 — Essential Commands You don’t need to memorize 100 Git commands. You need these 15. That’s it. 📊 See what’s happening: git status # run this constantly git log --oneline # compact commit history git diff # line-by-line changes 💾 Save your work: git add . # stage everything git add file.py # stage one file git commit -m "msg" # save a snapshot ☁️ Sync with GitHub: git push # upload commits git pull # get latest changes git clone <url> # copy a repo 🌿 Work with branches: git checkout -b feature-name # create + switch git checkout main # go back to main git merge feature-name # merge changes git branch -d feature-name # delete merged branch 🆘 Oops, undo: git restore file.py # discard file changes git revert HEAD # undo last commit safely The most important command? git status Run it before and after every Git command until it’s muscle memory. #Git #GitHub #CodingTips #Programming #DataScience
