1. Install Git (if not already installed)
First, install Git on your Linux system using the following command (Ubuntu/Debian):
sudo yum update
sudo yum install git

Configure Git
Before using Git, set your name and email:
git config --global user.name "Thirdy Gayares"
git config --global user.email "[email protected]"
Create a Repository
You can create a new Git repository (repo) in your project directory.
Create a Directory
mkdir myRepository
Navigate to your project folder:
cd myRepository
Initialize the Git repository:
git init
Create File

Git Status
This will show you the changes in your working directory, such as new files or modified files.
Add Files to Staging Area
git add .
Commit Changes
Once the files are staged, you can commit them. A commit is like saving a snapshot of your project at that point.
git commit -m "Initial commit with project files"
Check Commit History
You can see your commit history with:
git log
Set Up Github Repository
Push to a Remote Repository
You can push your changes.
Add a remote repository:
git remote add origin https://github.com/Thirdy-Lecture/Github_Push_Example_2.git
Push changes to the remote repository:
git push -u origin master
How to resolve this issue ?
Go to https://github.com/settings/tokens
Choose classic
Check The Repo and Set note and Expiration then click generate token
Copy and paste the token key
git push -u origin master
Username for 'https://github.com': thirdgyayares
Password for 'https://[email protected]': <Paste your Personal Access Token here>
Set up Credential Caching
If you don’t want to enter your token every time, you can cache your credentials using:
git config --global credential.helper cache
This will save your credentials for a while.
Alternatively, you can permanently store your credentials by using:
git config --global credential.helper store
This way, Git will store the credentials in a file, and you won’t be prompted for them again.
Check the repository on your Github

Pull Changes from Remote
To pull updates from a remote repository:
git pull origin master
