Introduction
Version control systems are essential for managing and tracking changes in projects, especially in software development. They allow teams to collaborate effectively, maintain a history of modifications, and ensure that previous versions of a project can be restored if needed. Git, one of the most popular version control systems, is widely used for its distributed architecture and robust feature set.
Git is a distributed version control system that allows developers to track changes, collaborate, and manage codebases efficiently. This post covers frequently used commands and their purposes.
Setting Up a Repository
Initialize a New Repository
git init
This command initializes a new Git repository in your current directory.
Clone an Existing Repository
git clone <repository-url>
Clones a repository into a new directory.
