Version control is a system that helps track and manage changes made to files and software code over time. It is commonly used in software development but can also be applied to any type of files. By using version control, developers can keep a history of all changes made to their code, allowing them to track who made each change, when it was made, and what specific modifications were made. This history can be useful for collaboration, debugging, and reverting to a previous version if needed. Version control systems also enable multiple developers to work on the same files simultaneously without overwriting each other’s changes. It provides features like merging and conflict resolution, allowing team members to integrate their modifications together. Some popular version control systems include Git, Mercurial, and Subversion. These tools provide numerous commands and functionalities to manage repositories, branches, commits, and more.
