git repository setting and commands


GitHub is an online repository. Many people find it very confusing to use GitHub, so I’ve decided to share my experience of using it on Linux Ubuntu.
So in this post we will discuss:
1. How to set up and clone repo to your local machine avoiding message: Permission denied (publickey).
2. How to transfer all changes you are making INTO Github
3. How to get those changes FROM GitHub

My way could not be the most efficient one, but it works for me. :)
How to setup up GitHub to your local machine ?

So for the first part, you need to download Git and set your SSH key. Thanks to the GitHub documentation, step by step guide is here:
How to clone your repo to your local machine ?

(in git terminology it’s called “checkout“)

First you need to find your repo address. It can be find on your GitHub repo page:

Copy the address in the box (git@github.com……/….git)

Open the terminal and go to the folder where you want to have your git to be located.

Type command:


Here is my output:

How to transfer all changes you are making INTO Github ?

(in GitHub it is called Push)

There are 3 steps to transfer your changes to GitHub:

a. You need to add files —> git add .

(“.” means all the files, no worries, it will add everything that was changed.)

b. You need to Commit you changes –> git commit -m “Message you want to see near your commit”

c. Push your changes to the server –> git push

My output:

On the repo I now see that README file has my commit message (I changed only README.txt):

How to get those changes FROM GitHub ?

git checkout

git pull

These commands will bring all the new stuff from GitHub to your machine.
