What exactly is going on here?

🔹 Git is a distributed version control system designed for tracking changes in source code during software development. It allows multiple developers to collaborate on projects, managing versions and facilitating branching for parallel development.

🔹 GitHub is a web-based platform built around Git, providing hosting for Git repositories. It enhances collaboration by offering features like issue tracking, pull requests for code review, and project management tools. GitHub is widely used for open-source projects and by teams to streamline development workflows and ensure code quality through collaboration and version control.

Installation and Login

First of all Download Git Bash from Google Chrome by clicking on it Git Bash
Open GitHub on chrome. Create your account via email and remember the username GitHub

git commit

git commit -m "[descriptive message]"
# commit your staged content as a new commit snapshot
git commit -m "New file added"
git push

Stages

**
1️⃣Untracked — — we add new files, but no commit it,, it is untracked, either we write in it or not

️2️⃣Modified — — changed

3️⃣ Staged — — file is ready to be committed

4️⃣ Un-modified — — unchanged

git reset

git reset [file]
git diff

git diff
# diff of what is changed but not staged
git diff - staged
# diff of what is staged but not yet commited
git log

git remote add origin https://github.com/thecallmeBilalAshiq/LocalRepo.git
git remote -v

♀️ Detail about Branches♀️

git branch

git branch
git branch -m new_name(rename the branch)

Instead of it you can use it.

git push -u origin main

-> Write previous line for one times then you can only run this command.

git push
git checkout

git checkout -b newbranch   # to create new branch
git checkout newbranch      # for shifting to different branches)

Delete a branch

git branch -d bilalbranch ==> delete

Merge branches

Method 01:

git diff main   # to check the difference between two branches
git merge main  # to merge new branch with the main branch

Method 02 — via github

PR (Pull Request)
after merging on github - ->

git pull origin main

to update it on your computer.
Undo anything, Undo any commit
git reset

git reset
 git reset HEAD~1 ==> to undo last commit

git reset
Fork
Fork on github to get other people repositories
Search their repository -> fork it -> complete
-> now that person repository is your repository
