Understanding Git and Version Control

Git is a distributed version control system that helps developers manage changes in their project's source code. Unlike centralized version control systems, Git allows multiple developers to work on the same project simultaneously without interfering with each other's progress. This is achieved through its branching and merging capabilities, which enable parallel development and seamless integration.

Version control is the practice of tracking and managing changes to software code. It is a crucial aspect of software development, as it ensures that developers can collaborate effectively, revert to previous versions if necessary, and maintain a complete history of changes over time. Git, being one of the most popular version control systems, is widely used in both open source and proprietary projects worldwide.

By providing a robust framework for managing changes, Git helps developers collaborate more efficiently, reduce errors, and maintain a high standard of code quality. One of the key features of Git is its ability to track the history of changes made to files, which brings us to the command "git show file history" – a tool that enables developers to explore this history in detail.
