Version control is a system that records changes to a file or set of files over time so that specific versions can be recalled later. Git is a distributed version control system that tracks changes in any set of computer files, usually used for coordinating work among programmers who are collaboratively developing source code during software development. Git is free and open-source software shared under the GPL-2.0-only license. Git has become the most popular distributed version control system, with nearly 95% of developers reporting it as their primary version control system as of 2022.
Git is used to manage changes to source code over time, and it helps software teams work faster and smarter. It is especially useful for DevOps teams since it helps them to reduce development time and increase successful deployments. Git is an open-source distributed version control system that helps software teams create projects of all sizes with efficiency, speed, and asynchronicity.
Git tracks changes to files by creating snapshots of the directory trees of files. Git snapshots the entire directory tree of files, whereas earlier systems for tracking versions of source code worked on individual files and emphasized the space savings to be gained from interleaved deltas or delta encoding the (mostly similar) versions.
Git has many commands that allow users to manage their repositories, including setup and configuration, getting and creating projects, basic snapshotting, branching and merging, sharing and updating projects, inspection and comparison, debugging, patching, email, external systems, administration, and plumbing commands.
