Git Tutorial: Everything you need to know

Git is an excellent free open-source distributed version control system designed to handle everything from small to very large projects. As an increasingly popular means of managing collaborative software development, it’s important that developers alike take the time to understand not only how Git works under the hood, but also its direct application within our own workflows. It’s also worth noting that the scope of this article will be limited to how Git directly relates to front-end web development. in this Git Tutorial, we will discuss the following points:

  • What is GIT?
  • What is Git Repository?
  • What are Git Commands?
  • Features of Git
  • Benefits of Git
  • Git vs Github

What is GIT?

Git is a version control system and integrated development environment (IDE) developed by the Open Build Service. Git is an open-source totally free distributed version control system developed to manage everything from simple to complex projects with speed, security, and efficiency. This git tutorial will walk you through the basics of this versatile tool, one step at a time, with helpful tips and examples. Click Here to Download Git.

It stores the entire history of the project in a series of commits, which are stored in a central repository. It also allows users to work on their own local branches, making commits as they go, and then merging those changes into their main branch later on.

Git is easy for beginners to pick up because it doesn’t require setting up a centralized server or any centralized storage – the entire history of a project is stored locally on each developer’s machine. With this model, every working copy of a project has its own complete repository with its own history and set of branches. The fact that all data for a project is self-contained means that there are no central points of failure, making it possible for several people to work on the same project at once without interfering with each other.

What is Git Repository?

A git repository is a place where you store code and files for your project. The best way to think of a git repository is as a “timeline” of all changes made to the source code. It’s a little like a history of what happened to the project over time but in this case, it’s not just the files that were changed or added, but also files that were deleted.

For example, if someone added a new file to the project and then deleted it again later, both actions would be recorded in the git repository. This might sound like a complicated system at first, but it’s actually much simpler than it sounds. After you understand the basics behind how git works, you’ll see that it’s actually very easy to use and manage. Git allows you to keep track of all different versions of your source code and even older versions. This is one of GIT’s biggest strengths as it allows you easily roll back any changes that might have broken something in your code without having to completely lose track of what you were doing earlier in time.

Git has various operations that let you work with a git repository and the stuff inside it. Following are the steps you can do:

  • Creating a repository, adding files to it, and checking out commits (files at particular states of the project)
  • Pushing your changes up to GitHub or Bitbucket
  • Pulling other people’s changes down from GitHub or Bitbucket
  • Making branches to work on stuff without messing up the main project

What are Git Commands?

Following are the Git Commands that are mostly used:

  • git init creates the repository and makes it the current working directory.
  • git add adds all the files you want to track with git to your staging area.
  • git rm will remove a file from your staging area. You cannot remove a file that hasn’t been added yet.
  • git mv will move a file from one location to another, but this is not considered best practice and is only done by accident or when rewriting history.
  • git status will show what you have staged and unstaged in your working directory.
  • git diff exhibits the changes you have produced compared to the previous commit.

Features of Git

Open-Source

Git is a decentralized open-source version control system. It provides a way of managing multiple projects with a centralized control system while encouraging collaboration between developers and version control systems via a web interface.

Scalable

Git is the most scalable open-source repository management tool available today. Compared to other such solutions, it enables you to keep your easily available by large projects, while at the same time offering powerful customization and deployment capabilities for individual projects and teams. Each Git repository comprises a series of files, commonly known as a ‘tree’. Each Git tree is divided into chunks called revisions. A revision may contain only text while others may contain files or other resources.

Distributed

Because of its distributed nature, Git is very good for managing code across multiple people and even computers. Below we will discuss some of the features of Git so you can understand what makes it so good and how it differs from other version control tools like Subversion or CVS.

Security

Git is well known for its security features. It’s implemented a number of protections to make it harder for hackers to take over your computer or steal data. When you install Git on a machine, it creates a fresh anonymous directory. All files and links in the directory are encrypted with strong encryption. Anytime you create a new file or link in the directory, it is also encrypted. This helps protect you from someone who might snoop on your files if they had access to your computer while you were using it without using a password. If you install Git on a machine that is already running an open-source operating system, some of its components may also be installed automatically via PAM libnotify, or other software libraries.

Speed

The most noticeable difference between Git and most other version control systems is speed. While most tools take an hour to clone or download, Git takes only minutes. It can store more than two million lines of code without taking up more than 1GB of disk space. Git is intuitive, easy to learn, and powerful so let’s explore some of its many features.

Data Assurance

Git is a Data Assurance tool designed to manage your data in a nice way. Data Assurance is the practice of ensuring the reliability, consistency, accuracy, authenticity, and verifiability of data & information.

Maintain the clean history

Git is a version control system with a very powerful command-line client called Git Bash. A feature of Git Bash that beginners don’t know about is called Git Rebase. It allows you to refactor changes into your commits as if they were entered.

Benefits of Git

Some of the benefits of Git are faster development, role-based access control, better defect tracking, no need to synchronize changes, etc.

Git integrity

Git is a tool that ensures the security and integrity of popular content being version controlled. The checksum is used to confirm that information was not lost during transmission or file manipulation.

Trendy Version Control System

One of the essential parts of every software project is Version Control System. It’s also known as revision control, version control, or source control. Using this tool, you can be assured that your project files are backed up securely so you can retrieve them if something bad happens. There are dozens of version control systems out there but I will be focusing on Trendy Version Control System because it’s free for personal use and easy to learn if you are new to the software.

Everything is Local 

The benefits of using Git are many. It has made our lives easier and made the development process faster. It makes it possible for us to work on different projects anywhere in the world without worrying about time zones, or having some special work printed out for you. The biggest benefit is that when you create a file in your home directory, it grows and changes without you having to push or pull. This makes it convenient for us to work on different parts of the same project without having to pause and wait for everything to sync up.

Collaborate to Public Projects 

Collaboration is important in software development. It unites developers around a common goal and allows them to easily share changes back and forth. By collaborating with other developers, you can make great improvements to software while avoiding complicated changes and extra work. There are two main benefits of using Git for source control: speedup up development and reduced friction when making changes. You can’t just change one line of code and call it a day—you have to commit the changes first and push them up to a central master branch before you can do any work on patches.

Prerequisites

There are a couple of prerequisites you need to fulfill before you can begin using Git. You need to be able to clone a repository and have your host machine provide you with an insecure repository. This prevented me from accidentally linking my own private key to the public key used for signing commits.

Git vs Github

Git vs Github is an engaging case study to describe how open source communities work. Git is known as a version control system. On the other hand, Github is a service that hosts Git repositories. Both Git and Github are strong tools, but they are different in purpose.

Because Git is an open-source project, you can download the code and run it locally if you wish. And because Github is a commercial service, you can also host your own Git repositories there if you wish–though this is not recommended for most people, since it’s more convenient to have things hosted for you by someone else.

Conclusion

If you’re new to Git and want to learn more, we hope this tutorial helped. It’s not in too much detail, but I hope it served as an introduction to the basics. As you continue along your quest to master Git, keep an eye out for additional blogs, documentation, and other learning resources. Perhaps the best way to get started is to experiment in a Git repository on your computer and see how Git behaves when you’re trying out different commands.
