Introducing Git & GitHub – DEV Community


We’ve already coated git prematurely, and now we’re additionally acquainted with GitHub and the options offered by GitHub. On this lesson, we’ll sync the native repository with GitHub; you’ll get an entire concept of how one can sync your native repository with the distant repository of GitHub.



Let’s get began

We’ve coated Git & GitHub intimately. We discovered that git is a Distributed Model Management System, and GitHub is a web-based git, model management repository and web internet hosting service. Moreover, we’ll learn to synchronize the Native repository with GitHub on this lesson.



Creating native repository

First, we have to create an empty listing. Use the next command.

mkdir <gitandgithub>
Enter fullscreen mode

Exit fullscreen mode

Then, we have to Navigate to the Listing we created earlier with the next command.

cd <gitandgithub>
Enter fullscreen mode

Exit fullscreen mode



Git Init

Now we created the Listing; we will initialize the git repository within the empty repository utilizing the next command.

git init
Enter fullscreen mode

Exit fullscreen mode

Keep in mind that the command ls -A is used to record the .git/ folder on the terminal as a result of .git/ is the hidden file within the working listing.
Git Init



Git add



Including File Utilizing Terminal

We are able to create a file utilizing the next command contact index. html and edit the file by means of the terminal simply utilizing the vim or nano editor.

vi index.html
Enter fullscreen mode

Exit fullscreen mode

You may also learn the textual content contained in the file utilizing the next command.

cat index.html
Enter fullscreen mode

Exit fullscreen mode



Git standing

So recordsdata at the moment are added to the Listing. Earlier than we add the recordsdata to the staged space, firstly, we have to test the standing of the git repository, which recordsdata are modified or deleted within the Listing, which might be checked utilizing the git standing command.



Including file to the staging space

Now, we have to stage our recordsdata, that are added to the Listing, to trace our recordsdata each time we modify, delete or add to the Listing. With the git add . command, you possibly can add your recordsdata to the staged space, after which with the assistance of the git standing command, you possibly can test the standing of your git native repository.



Git commit

When the recordsdata are within the staged space, you’ve got dedicated on the recordsdata; if you make modifications on the file, the commits historical past is created and might be accessed later utilizing the command git log. To Decide to the modifications, you should utilize the next command.

git commit -m "Describe message."
Enter fullscreen mode

Exit fullscreen mode

fundamental.css file can also be added to the Listing, which suggests the modifications have been tracked within the git repository. To stage the modifications, we will use the git add . command, and to commit, we will use the command git commit -m "Including fundamental.css file. Everytime you modify, delete or change the file or folder, you should repeat this course of and test the standing of the git repository. You should use the command git standing.



Git department

As we’ve got already mentioned the ideas of the branches intimately, right here we have to rename the grasp department to the primary department as a result of Github’s new repositories are pushed to the primary department. Use the next command to rename the grasp department to the primary department.

git department -M fundamental
Enter fullscreen mode

Exit fullscreen mode



Creating a brand new GitHub repository

You may must discover a “+” signal on the prime proper of your GitHub account to get this began. The profile tab is subsequent to it. Click on the profile, and you will note a dropdown with the primary choice to create a “New repository.” As soon as clicked, you can be redirected to a different web page the place you’ll have to set sure info relating to your mission, comparable to offering your repository’s identify, including an outline of the mission, and declaring the repository as public. Don’t choose the README file and License. We’ll create these recordsdata afterward.

GitHub Repo

When you observe the above picture, you’ll redirect to the handbook, which could be helpful for the newbie.

Git Repo



Git Distant

Now, let’s return to the native repository the place we created the index.html file and fundamental.css file; within the git bash terminal, we have to add the GitHub repository which we’ve got created earlier; with the next command, you possibly can add the distant repository to the native git repository.

git distant add origin <GitHub REPO URL>
Enter fullscreen mode

Exit fullscreen mode

To get the GitHub Repository URL, you should go to your repository created earlier, and by clicking on the Code button, you’ll get the GitHub Repo URL.

The command will appear to be this.

git distant add origin https://github.com/gitlearning892/gitlearning892.github.io.git

Enter fullscreen mode

Exit fullscreen mode

With the git distant -v command, you possibly can test the distant origin is added to the native repository or not.

When you by accident add the unsuitable repository to your native repository, you possibly can change the present distant repository with the next command.

git distant set-url origin <GitHUB REPO URL>

Enter fullscreen mode

Exit fullscreen mode



Git push

The Git push command is used to add native repository content material to the distant repository. Pushing is how one can switch commits out of your native repository to a distant repository. Pushing can overwrite modifications; cautions ought to be taken when pushing to the distant repository.

git push -u origin fundamental
Enter fullscreen mode

Exit fullscreen mode

Go to your repository and refresh it; you will note your whole native content material now pushed to the Github repository.

A popup will come for the Github authentication. Click on on Login utilizing a browser and supply your credential to push your whole modifications to the Github repository.



Git pull

The git pull command is used to fetch and obtain content material from a distant repository and instantly replace the native repository to match the content material.
For instance, If somebody out of your crew made some modifications in a file or created some file on a distant repository. A developer created a file named consumer.txt, however you do not know the modifications made on the distant repository. To illustrate you’ve got created one other file named crew.txt. After you commit the file and attempt to push that file to your distant repository, git is not going to mean you can push your code as a result of the distant repository accommodates work that you just shouldn’t have domestically. So, On this case, the git pull command is used to fetch and obtain content material from a distant repo to a neighborhood repo.

Let’s create a brand new file on GitHub Repository.

GitHub Repository
As customers.txt file is created on the GitHub Repository however this file just isn’t obtainable on the Native repository.
You’ll be able to pull your GitHub modifications utilizing the command

git pull origin fundamental
Enter fullscreen mode

Exit fullscreen mode



Git clone

git clone is a Git command-line utility that’s used to focus on an present repository and create a clone, or copy, of the goal repository. The command for cloning the repository is.

git clone <REPO-LINK>
Enter fullscreen mode

Exit fullscreen mode



Abstract

On this lesson, we’ve got discovered methods to sync the native repository with GitHub and methods to use git push, pull, and fetch instructions with GitHub. We’ve additionally discovered methods to push modifications to GitHub from a neighborhood repository.
