To check if Git is installed on your system, open your terminal and run the following command:

What is Git?
Git is a distributed version control system designed to manage and keep track of source code changes in software development projects. It allows multiple contributors to work seamlessly together on code, making it easier to collaborate and maintain an organized project history.
Benefits of Using Git
Using Git provides several advantages:
-
Collaboration Features: Git allows multiple developers to work on the same project simultaneously without conflict. Branching lets developers create separate lines of work without affecting the main codebase.
-
Version History Tracking: With every commit, Git saves a snapshot of your code at that point in time. This lets you easily revert to previous versions if needed, making it invaluable for debugging and historical reference.
-
Branching and Merging Capabilities: Git’s branching system allows you to create isolated environments for new features, bug fixes, or experiments. This means you can work on enhancements without disturbing the main project until you’re ready to merge.
Why Check if Git is Installed?
Before diving headfirst into coding and project collaboration, it's essential to ensure Git is ready for use. If Git is not installed, you may encounter unnecessary delays and setbacks in your development process.
Common Scenarios for Checking Git Installation
-
Starting a New Project: Before initiating or contributing to a project, confirming Git's presence is crucial to ensure version control practices are in place.
-
Collaborating on Existing Projects: Joining a team or contributing to a project that uses Git means you need to have it installed and properly configured.
-
Setting Up CI/CD Pipelines: Continuous Integration and Continuous Deployment require Git to manage the deployment of code effectively. Checking installation beforehand will streamline this process.
How to Check If Git is Installed
Checking Git Installation on Windows
To verify if Git is installed on a Windows machine, follow these simple steps:
