Self notes on how to get acquianted with git.

• Sabse pehle maine VS Code pe aake ctrl + shift + p kia
• fir git: clone command kari     - waha se fir repository choose kari (yeh tab ka process hai jab already website pe repo banai hui thi)
• uske baad fir repository clone hogayi

• sab kuch clean kardeta hai yeh command prompt pe jo bhi aatank machaya jo hota hai
• linux command hai so sabhi jagah chalega

• iss se folder humara git ki repository me initial hojata hai

git init

• iss se hume saare untracked/tracked changes pta chalte hai
• agar kuch changes nahi ho rakhe ho file me toh "working tree clean" ka aata hai msg command prompt pe
• varna jo files me changes kare hote hai unka dikhata hai

git status

• Command prompt pe git clone fir http waali link paste karni hogi
• iss se hum github pe jo repository hoti hai usko clone karne ki koshish karte hai

try karke dekhna hai ki hoga ya nahi ?

git clone https://github.com/Ashish-012/Whiteboard.git

What is staging area ?

Temporary save ki tarah hota hai baas aur kuch nahi. Suppose tumne kuch kaam kara aur chahte ho ki ab woh save hojaye toh

• iss command se hum jo untracked changes ko staging area me le aate hai

Ab kuch chudaap kardia tumne aur chahte ho waapis aana toh revert ka function hota hai. Aage discuss karenge.

git add (file name with extension)

git add . [This will add all the file which have changes to staging area]

• jab humne saare changes karliye hote hai aur staging area se finally apni working branch pe daalne hote hai tab iska use karte hai

git commit -m "(Message Name)"

• jo bhi changes kare hai abhi tak woh saare push kardo working branch me

git push

Need to have more clarity on this

• Iss command se hum yeh dekhte hai ki jis file me changes huye hai woh hai kya exactly     - Red line -> original state     - Green line -> New State(change hua hai)

git diff (File Name)

• iss se hume yeh pta chalta hai ki kya changes huye hai as per the comment

git show (hash number)

• iss se hum project ke saare logs dekh sakte hai

git log (iss se saare logs dikhenge)
git log -5 (last 5 recently logged entries)
git log --oneline (shows only commit message)

 -  basically tells which branch are we on  git  git branch  

Suppose hume new feature laana ho aur current working product ko chhed na nahi hai. Toh hum branch nikalenge.

Yeh tree ki tarah hogaya ki root main hai apna aur branch nikal ke new cheez pe kaam ho raha. Agar sab sahi raha toh root se merge hojayega

git checkout -b thunderBolt [this will create a new branch named thunderBolt]
git checkout main [iss se hum main branch pe aajayenge]

This will create a new branch from the working tree. New branch's name would be thunderBolt.

Agar hum git checkout (main branch) kare toh hum seedha original root pe aajayenge. Yaani checkout basically branches pe travel karne ke liye hai

• branches pe hume kya operations karna hai uss hisaab se hai

git branch -d (branch name) [Iss command se hum branch ko delete kar sakte hai]

Jis branch pe kaam kar rhe hai usko delete nahi kar sakte hai. Yaani jis daali pe ho usko nahi kaat sakte jab tak dusari daali pe naa chale jao

git branch (new branch)

Merge karne ke liye zaroori hai aap main branch pe ho

• Jo changes kare hai kisi branch me agar woh main root branch ke saath merge karne ho toh yeh karte hai
• Jis branch me changes kare hai pehle unko aaram se "add, commit" karlo
• Fir main/root branch pe aao via checkout command
• uske baad command likho

git merge (kaunsi branch merge karni hai uska naam)

Iska kaam dekhna hai ki kya karta hai

• iss me dekhna hoga ki kya kaam hota hai

Yaha se dekhna hai

1. git reset --hard HEAD^
   • yeh command humare code changes and commit dono ko hata dega
2. git reset --soft (hash name)
   • iss se sirf commit hatega code changes present rahenge.

Need to see about this properly. Commits ka naam change karne me help karta hai yeh sahi se.

git commit --amend 

Yaha pe username change kia hai via

git config --global user.name "(new name)"
