This Git tutorial covers all aspects of functions and features to help programmers leverage the use effectively.

Application of Git

Git has been used by organizations, governments, businesses, professionals, and even startups to manage their code, task allocation, and project management. Here are the main applications of the Git platform.

Product Management

Git allows hundreds and thousands of developers to work on the same project. It is especially useful for integrating frequent customer feedback in the system and then updating the changes directly in the source code. Almost every top MNC (Microsoft, Amazon, Facebook) has online products' source codes on Git repositories.

Source Projects

Git has become a popular tool for IT experts, organizations, and top corporates to share their code with the developers. Even small and medium IT organizations today are using Git to manage their source code efficiently. Git is also compatible with web standards (HTTP, FTP) to seamlessly manage repositories.

Real-time Web Applications

Git is a preferable choice for building real-time web applications and Android applications. With digitization, organizations have transformed their procedures online and offer real-time connectivity. Git, acting as a DevOps tool, allows continuous integration and development to enhance team productivity.

Encourages Distributive Development

One of the main features of the Git platform is to allow distributive development. Teams from around the work on the same project and perform multiple tasks simultaneously. Git empowers businesses and organizations to work in a collaborative environment.

Several Government organizations use GitHub to build, share, and manage procedures. Thus, it allows other organizations to request the source code and maintain a uniform software development cycle across multiple levels.

Implementation across multiple Operation System

Git allows the use of its platform through multiple operating systems such as macOS, Solaris Windows, Red Hat, Fedora, and many other Linux based systems. Git is also used to develop the core Linux kernel and manage code efficiently.

• JGit is a pure combination of Java software library and Git version control system. JGit has been successfully deployed in EGit (a comprehensive Git client for Eclipse), Gerrit code review tool, and also powers many such applications. JS-Git uses a specific JavaScript implementation, which is a subset of a Git.
• Go-git is another robust combination of Git and pure Go. This Go-git is an open-source implementation used for offering encryption and as a SQL interface for Git code repositories. Git also acts as a Dulwich implementation for use in multiple Python versions.  
• Libgit2 is a specific implementation of Git with the ANSI C software library. Libgit2 doesn't depend on any particular OS and is available across multiple platforms such as macOS, Windows, and BSD. Several programming languages such as Python, Haskell, and Ruby can run on this.

In this Git Tutorial, you will also get to know about various implementation and use cases of large projects benefiting from this collaboration tool.

Git Tutorial: Table of Contents

1. What is Git: Features, Command, and Workflow in Git

In this Git tutorial, you will get to know all about this free, open-source tool to handle, track, and efficiently manage files. Git platform is available under the GNU license and used for maintaining past and current variants of web pages, source code, product code, etc.

Git features tracking management, non-linear development, allows backup, branching, merging, and supports a scalable environment. Commands for Git are present for building repositories, parallel development, syncing repositories, and making changes. Git workflow has three main parts: working to make changes in the directory, staging to check the new code, and Git directory to commit the latest changes to the platform.

2. What is GitHub and How to Use it?

With more than 40 million users and 100 million repositories, GitHub is one of the widely used programming resources online. GitHub acts as a commercial Git repository hosting service that runs online with a web-based graphical user interface. GitHub has the backing of the largest coding community and gives global exposure to your code. GitHub allows remote team members to work from any location with seamless collaboration.

3. How to Install Git on Windows?

Git is a sophisticated tool for source code management that allows programmers to manage a large number of project files effectively. You can install Git on Windows by downloading the software from the official website. Then, use commands to build a local repository to have seamless connectivity with the server repository. You can learn the basic Git commands to push, pull, and merge to stay on the right path with many developers for completing the project timely.

4. Git vs. Github: Major Differences

There is a vast difference between the functionality of Git and GitHub. Git is an open-source, free distributive version tool and completely free to use. Git offers a desktop GUI and server connectivity for developers to work on their local system and then push their code to merge on the remote or central server. G

On the other hand, GitHub is a genuine web-based hosting solution for Git repositories. GitHub provides all the features of Git, along with more collaborative functions such as project management, bug tracking, and support ticket management. Learn the Git tutorial to uncover more!

5. What is GitLab, and How to Use it?

GitLab acts as a central solution provider for offering Git repositories with both free and paid versions. GitLab empowers teams to share their work on multiple projects, monitor source code, and build more optimized software.

GitLab enhances team productivity and improves product life cycles to bring forth more value to the customers. GitLab is a comprehensive DevOps platform that allows ease of project management, user permission control, and enjoys more functionalities at a minimal price every month.

6. Git Push Command

Push command is one of the main commands of the Git distributed file system. Push command allows the changes in the local repositories to transfer to the online server or the remote repository. Once the changes are complete in the local repository, a user can use this push command to make these changes global available on the Git repository. Get to know all the procedures for the Git push command in the Git tutorial now.

7. Git Pull Command

Pull command is an essential command in the Git platform. It allows users to fetch and merge their code modifications from the central remote repository to their local repository. 'Git pull' command is a sequence of two commands with 'Git fetch' to get the remote repository, followed by the 'Git merge' to combine multiple commits into a single branch. You can also check the different commands used in the Git Pull procedure in this Git tutorial, along with stepwise instructions to fetch files from the online repository.  

8. How to Resolve to Merge Conflict in Git?

In this Git tutorial, you will learn the different ways of merging conflict that emerges in the conflicted Git state. Merge can go into a conflicted state in two conditions. Firstly, when starting the merge process due to the still pending changes in the branches. Secondly, during the merged process, when there are still conflicts between the local and server branches that need to be merged.

9. Git Interview Questions and Answers

Git plays a crucial role in adapting to DevOps procedures within any organization. Git provides collaborative features for task management, bug tracking, wikis, project management, etc.

This Git tutorial offers a step-by-step guide and top Git interview questions and answers for basic, intermediate, and advanced levels. Prepared by industry experts, these questions will help you understand the different aspects of Git and its practical applications. Especially for software development professionals, Git is an essential part of their job responsibilities and can help them procure topmost positions in the MNCs and corporates.
