Git is a distributed version control system (DVCS) that allows multiple developers to collaborate on a project, tracking changes to files and coordinating work seamlessly.

Initializing a Repository:

git init

Cloning a Repository:

git clone -b <branch-name> <url> <folder-name>

Working with Branches:

Create a new branch:

git checkout -b <new-branch>

Switch branches:

git checkout <branch-name>

Create and Switch branches:

git switch -c <new-branch>

List all branches:

git branch

Staging and Committing Changes:

Add files to staging area:

git add .

Commit changes:

git commit -m "message"

View changes before staging:

git diff

Remote Repositories:

Add a remote repository:

git remote add origin <remote-repository-URL>

List all remotes:

git remote -v

Push changes to a remote repository:

git push -u origin <branch-name>

Pull changes from a remote repository:

git pull origin <branch-name>

Stashing Changes:

Stashing in Git allows you to temporarily save changes that are not yet ready to be committed, so we can switch to another branch without losing your progress. It is used when you need to quickly switch contexts or update your working directory without committing incomplete work.

Stash changes:

git stash

Apply stashed changes:

git stash apply

Configuration:

Change user name:

git config --global user.name "name"

Change user email:

git config --global user.email "email"

Reset:

Soft reset:

git reset --soft HEAD^

Moves to the previous commit and discards all changes.

Hard reset:

git reset --hard HEAD^

Moves to the previous commit but keeps all changes.

( HEAD is a reference to the current commit &
notation HEAD^ refers to the parent commit of the current HEAD )
