Introduction to Git and GitHub

Hello, guys, this is Harshith and in this article, I am going to walk you through the basics of git. So let’s get started

First I am going to select a folder (test)

Ok now I am going to break down the steps into 4 different segments: Initialisation, Staging, Committing, and finally Pushing

Now I am going to start by installing git using this command

sudo apt update # Updating Packages
sudo apt upgrade # Upgrading Packages
sudo apt install git

I am going to use the command “git init” which is going to create a new hidden folder called .git

ls -la

Then I am going to create a new file called a.txt.

Now we can see an ‘x’.

This indicates that some file is being Untracked. To check which file is, We are going to use

git status

We can stage it using this command which will add all the files

git add . # '.' ➝ all the files and folders of the directory

Now when we run “git status” we can see that we need to commit a.txt.

Now we need to commit the changes using this command.

I normally use this format to make my commits so that it is easier for me to check the details. ‘Name of the commit | Date’

Now for the last step, we need to push it to a repository or repo. I am going to use one of the popular git-service called GitHub

First, create a repository. Make sure it’s private because no one wants to see an empty a.txt file

Then add an ssh key which you can by going to Profile>SSH and GPG Keys

Ok now copy the ssh URL and then go to your terminal and use this command which is going to connect our repo to GitHub

git remote add origin {https} # don't add the curly braces!

Now you can push the repo by running

git push -u origin master

This is going to push all the files to our private repo. Then reload the page and you will find a.txt

You can’t directly download git using the command line so you will have to download it from https://git-scm.com
