verziókezelésre

Verziókezelés (version control) is a system that records changes to a file or set of files over time so that you can recall specific versions later. This allows you to revert to an earlier state of the files if necessary, compare changes between versions, and collaborate with others on the same project. It is an essential tool for software development, but also useful for managing any collection of files where tracking changes and history is important, such as documentation, creative works, or configuration files.

The core concept of version control involves a repository, which is a storage location for the project's files and their entire history. When you work on a project, you typically make changes to local copies of the files. These changes are then "committed" to the repository, creating a new version or "commit." Each commit has a unique identifier and usually includes a message describing the changes made.

Popular version control systems include Git, Subversion (SVN), and Mercurial. Git is currently the most widely used system due to its distributed nature, speed, and flexibility. Distributed version control systems allow each developer to have a full copy of the repository, enabling offline work and more robust branching and merging capabilities. Branching allows developers to create independent lines of development, facilitating experimentation without affecting the main project. Merging is the process of integrating changes from one branch into another.

Version control systems are crucial for maintaining project integrity, facilitating collaboration, and providing a safety net for development. They help prevent data loss, enable easy rollback of erroneous changes, and streamline teamwork by providing clear visibility into who changed what and when.
