Basic Git command and remotely update to Github

In this tutorial i’ll write basic git command to create local git repository , staging changes, committing and push changes to remote git repository.

---

First, We have to know what is git?

Git is a open source distributed version control system.It is free and designed to handle everything from small to very large projects with speed and efficiency.

Now one question may arise on our mind. What is version control system?

well, Version control is a system that records changes to a file or set of files over time so that you can recall specific versions later.

Now we know what is git and why we must use it.
Our next step would be setting up git in our local machine.

Setup Git

*Linux

sudo apt-get install git

*Windows
Simply download the installer exe file from the GitHub page, and run it. Git installer
Lets start working with git!

1. Empty Git Repository Setting Up
   To initialize a empty git repository in local machine first you have to go the directory where you want to create repository. Then write this command in terminal.
   
   

   git init

   
   
2. Check current Status of repository
   After initializing empty repository lets check current condition of repository.To do so, type this command in command line
   
   

   git status

3. Adding changed file to commit
In our last step we created a file called helloGit.html and checked status whether it shows update or not. Now we will add this html file to stage state so that we can track further change happen to it.
How can we do that? Write this command on terminal

git add helloGit.html

Now check current status using previous command



4. Now Committing new this change with a hints
Now we have to keep information about this change so that we differentiate it with previous changes. To do that, write this command in terminal.

git commit -m "Creating helloGit.html page"

Now lets check current git repository status using git status
and we will see this


5. Now we’ll push it to github.com
In this step we’ll push our updates to github.com.
To do that we have to create a repository in github.com.
Go to github.com and create a new repository name basicGitCommands
Now to connect basicGitCommand repository from our local machine , we have to set it as origin.To do that, we have to write this command.

git remote add origin https://github.com/shuvrow/basicGitCommand.git

Here shuvrow is my user name. Replace it with your user name.
After writing this command we will see this in terminal.
If you want to create repository from your local machine using command line, write this command in terminal

curl -u 'shuvrow' https://api.github.com/user/repos -d '{"name":"basicGitCommand"}'

Now we have external git repository in github.com. So all we’ll going to push it in github.com
To do this, we have to write this command in terminal.

git push origin master

Yes!!! we have done it!
Here is the view of github.com/shuvrow/basicGitCommand.git
