Version control, also known as source control, is the practice of tracking and managing changes made to the source code and configuration of a project over time, through the use of a software called a version control system (VCS).

It allows developers to maintain a complete history of all changes made to a project, to compare those changes between them, and to revert them back to a previous state if needed.

What is Git?

Git is a free and open-source command-line interface version control system available on Linux, macOS, and Windows.

It allows developers to track the changes made to their projects by saving complete snapshots of all the edited files at specific points in time, in the form of a browsable history.

It allows them to experiment with new features without affecting the main codebase and seamlessly integrate those changes once they are finalized.

Last but not least, its distributed model allows multiple developers to work collaboratively on the same project, even if the central server goes offline, and later synchronize their changes when the server is restored.

In short, Git is an essential tool for developers to efficiently manage, share, and maintain codebases in projects of any size.

Installing Git

git is the command-line tool used to manage both local and remote Git repositories.

On Linux using APT

To install Git on Linux, you can use the apt-get command:

$ sudo apt-get update$ sudo apt-get install git

To verify that the installation was successful, you can print Git's current version using the git --version command:

$ git --version

On macOS using Homebrew
