A step-by-step guide to Git

If you ‘ve never used Git, you may be aflutter about it. There ‘s nothing to worry about—just follow along with this bit-by-bit getting-started lead, and you will soon have a new Git depository hosted on GitHub .
Before we dive in, let ‘s open up a coarse misconception : Git is n’t the same matter as GitHub. Git is a version-control arrangement ( i.e., a patch of software ) that helps you keep track of your computer programs and files and the changes that are made to them over time. It besides allows you to collaborate with your peers on a plan, code, or file. GitHub and like services ( including GitLab and BitBucket ) are websites that horde a Git server plan to hold your code .

Step 1: Create a GitHub account

The easiest way to get started is to create an account on GitHub.com ( it ‘s release ) .
Create a GitHub account

opensource.com

Pick a username ( for example, octocat123 ), insert your electronic mail address and a password, and snap Sign up for GitHub. Once you are in, it will look something like this :
Signed in to GitHub

opensource.com

Step 2: Create a new repository

A depository is like a position or a container where something is stored ; in this case we ‘re creating a Git repository to store code. To create a new repository, choose New Repository from the + sign dropdown menu ( you can see I ‘ve selected it in the upper-right corner in the image above ) .
Create a new repository

opensource.com

Enter a name for your repository ( e.g, “ Demo ” ) and snap Create Repository. Do n’t worry about changing any other options on this page .
Congratulations ! You have set up your first repo on GitHub.com .

Step 3: Create a file

once your repo is created, it will look like this :
New repo on GitHub

opensource.com

Do n’t panic, it ‘s simpler than it looks. Stay with me. Look at the section that starts “ … or create a modern repository on the instruction line, ” and ignore the rest for now .
Open the Terminal broadcast on your computer .
Terminal

opensource.com

Type git and hit Enter. If it says command bash: git: command not found, then install Git with the command for your Linux operational arrangement or distribution. Check the initiation by typing git and hitting Enter ; if it ‘s installed, you should see a bunch of information about how you can use the command .
In the concluding, type :

 mkdir Demo

This control will create a directory ( or folder ) named Demo .
Change your terminal to the Demo directory with the command :

 cd Demo

then enroll :

 echo "#Demo" >> README.md

This creates a file named README.md and writes #Demo in it. To check that the file was created successfully, enter :

 cat README.md

This will show you what is inside the README.md file, if the file was created correctly. Your terminal will look like this :
Terminal

opensource.com

To tell your calculator that Demo is a directory managed by the Git course of study, enter :

 git init

then, to tell the Git program you care about this file and want to track any changes from this point forward, enroll :

 git add README.md

Step 4: Make a commit

then far you ‘ve created a file and told Git about it, and now it ‘s time to create a perpetrate. entrust can be thought of as a milestone. Every prison term you accomplish some work, you can write a Git commit to store that adaptation of your file, so you can go back later and see what it looked like at that decimal point in prison term. Whenever you make a switch to your file, you create a fresh adaptation of that file, different from the previous one .
To make a invest, enroll :

 git commit -m "first commit"

That ‘s it ! You just created a Git invest and included a message that says first invest. You must always write a message in entrust ; it not merely helps you identify a entrust, but it besides enables you to understand what you did with the charge at that point. sol tomorrow, if you add a newly piece of code in your file, you can write a entrust message that says, Added raw code, and when you come bet on in a calendar month to look at your give history or Git log ( the list of commits ), you will know what you changed in the files .

Step 5: Connect your GitHub repo with your computer

now, it ‘s time to connect your computer to GitHub with the dominate :

 git remote add origin https://github.com//Demo.git

Let ‘s look at this command footfall by tone. We are telling Git to add a remote called origin with the address https://github.com//Demo.git ( i.e., the URL of your Git repo on GitHub.com ). This allows you to interact with your Git depository on GitHub.com by typing origin rather of the full URL and Git will know where to send your code. Why origin ? Well, you can name it anything else if you ‘d like .
now we have connected our local transcript of the Demo repository to its outback counterpart on GitHub.com. Your terminal looks like this :
Terminal

opensource.com

now that we have added the outback, we can push our code ( i.e., upload our README.md file ) to GitHub.com .
once you are done, your terminal will look like this :
Terminal

opensource.com

And if you go to https://github.com//Demo you will see something like this :

Demo repo on GitHub

opensource.com

That ‘s it ! You have created your first GitHub repo, connected it to your calculator, and pushed ( or uploaded ) a file from your calculator to your repository called Demo on GitHub.com. following time, I will write about Git clone ( downloading your code from GitHub to your computer ), adding newfangled files, modifying existing files, and pushing ( uploading ) files to GitHub .
