description Version Control with Git Overview
Git records changes to files and preserves a project's history, making it possible to examine earlier work or restore a previous state. Its distributed design gives each normal repository clone its own history rather than relying solely on one central copy. Developers can work on separate branches and bring changes together when they are ready to share them. For programmers and software engineers, this makes collaboration easier to manage while keeping a record of how the code evolved.
Platforms such as GitHub build shared review and hosting workflows around Git, but Git itself remains the version control tool. The skill includes deciding what belongs in a change and resolving conflicts when work overlaps. It also benefits solo developers who need a dependable way to track experiments and recover earlier code.
help Version Control with Git FAQ
Who created Git and when was it released?
Git was created by Linus Torvalds, the creator of the Linux kernel, in 2005. Torvalds developed it in response to the revocation of a free license for BitKeeper, the version control system previously used by Linux developers.
What is the difference between Git and GitHub?
Git is the underlying distributed version control software used locally on a developer's machine to track changes in files. GitHub is a cloud-based hosting service built around Git that allows developers to store, share, and collaborate on repositories remotely.
How do you revert a bad commit in Git?
To undo a committed change while keeping the project history intact, developers typically use the `git revert <commit-hash>` command, which creates a new commit that inverses the changes. If you want to completely wipe uncommitted local changes, you would use `git reset --hard`.
What is a pull request in Git workflows?
A pull request is a feature of Git hosting platforms like GitHub and GitLab that facilitates code review. It allows a developer to propose changes made in a feature branch to be merged into the main repository, enabling team members to review the code before approval.
