A free, open-source distributed version control system that tracks changes to code and lets many developers collaborate safely.
Git was created by Linus Torvalds in 2005 to manage development of the Linux kernel. Every developer has a full copy of the project history on their own machine, so they can work offline, experiment on branches, and merge changes later.
Core commands include git clone to copy a repository, git commit to save a snapshot of changes, git branch to start a separate line of work, git merge to combine branches, and git push and git pull to sync with a shared remote. Hosting platforms such as GitHub, GitLab, and Bitbucket add pull requests, code review, issue tracking, and CI/CD integrations on top of Git. Learning Git is considered a basic skill for most software roles.
