What is Git? And its Overview and Uses

Git Overview and its Uses

What is Git

It is a tool used by the DevOps team for managing the source code. Most of the time the coding team will store the codes in a place and don’t make a copy for themselves. Therefore any changes made will go unnoticed. Thus this OS tool helps both large and small projects to be handled efficiently by organizing the source codes. It is a free version control system. In this blog let us study in detail its overview, uses, and other details in a simple form allowing every beginner to get a grasp on it. 

If you want to have a detailed study with practical sessions, then we suggest you opt for DevOps online training and get benefitted. 

Git Overview

First things first, when you want to know what is Git the definition alone won’t help. Let us take a look at its overview for a better understanding. A project might involve more than one developer. In that case, not all will have time to discuss and hence each will work on their assigned task. They will create codes and store them on the server as directed by the organization. However, they don’t have a copy of it and hence any changes made by others will not get updated. This makes the developer feel clueless on bugs etc. Therefore, Git will help to store these codes to the respective local machine and that will provide a copy and allows everyone to track for changes, etc. Every developer will be able to connect with others too. 

The basic idea in DevOps methodology is to let all work together and do away with the silos traditional method. For that to happen successfully Git is very important. 

Git full form is GNU interactive DevOps tools and is a distributed version control tool with a license. It maintains the past and present source codes as well as the website pages. Having said that it is distributed, Git allows each programmer to have a copy of the code in their machine. The changes made in the local machine will get reflected in the central system as well as updating the repository automatically. 

You can easily master the overview of Git by registering for a DevOps certification course to work on a six months project for direct experience.

Git Features 

Git is used to tracking all history and maintain current code as well 

It is available for free and is open source 

It allows making backup and reflecting the changes in the local machine to the server 

It enhances teamwork by allowing developers to stay connected 

It is scalable and helps in nonlinear development

What is Git Workflow?

The 3 primary states of the workflow include the Working directory, Index, and repository. The first one will modify files in the current directory, the second one will stage files and include the snapshot and the last one will commit to storing the snapshot to the Git directory. 

How to Get Started with Git 

You have understood what is Git and now let us explain how to work on it with some basic steps. 

1. Download Git – Click on this link to install 

2. Verify installation using the following command – git –version 

3. Create a folder in the system for a local repository and call it sample-git-demo

4. Open that folder and use the command to add a local repository to your project 

cd sample-git-demo 

git init

5. Then you can add code, stage and commit them 

Now I know it is getting technical and hence I would suggest you attend DevOps online courseto get hands-on work experience with Git. 

Basic Git Commands 

Git init – for creating a repository 

Changes can be made using the commands add, commit, and status 

Use parallel development with the branch, rebase, merge 

Synch repositories using command push, pull, add origin 

Benefits of Using Git 

It saves time and increases the productivity 

You can work offline and there is no need to stay connected to the central repository always. Everyone can operate on their respective local machines and still update the central server 

It is now possible to undo and redo if you have committed any mistakes with Git 

Making useful commit is very simple with Git and you can now make granular commits using its staging area in the workflow 

Create modules, submodules and work the way you want to and there is no need to stick on to hard rules as you can connect to the central repository anytime 

Know More About What is Git

With these basic inputs, we are sure we kindled your curiosity to know more about Git and how to use this tool in DevOps. Now it's time for you to choose the DevOps Training to learn Git, install it, master the commands and safely store your source codes. No worries about forgetting source codes with Git now. Also, don’t bother about another developer's work as it gets automatically stored in the central server which you can refer to anytime you like to.
