In the context of Git, what is a 'Fork' primarily used for?
- Creating a new branch in a repository
- Cloning a repository from one remote to another
- Diverging from the main codebase
- Creating a duplicate of a repository
In Git, a 'Fork' is primarily used for cloning a repository from one remote to another. Forking is commonly associated with collaborative development on platforms like GitHub, where a user can fork a repository to create their copy. This copy is independent and can be modified without affecting the original repository. Forking is a fundamental concept in open-source collaboration and contributes to the decentralized nature of Git.
An IDE integrated with Git is used to resolve conflicts. What feature would be most useful for a developer who is handling complex merges?
- Three-way merge
- Rebase
- Cherry-pick
- Stash
In complex merge scenarios, a three-way merge helps by considering the common ancestor, the source branch changes, and the target branch changes. This approach minimizes conflicts and provides a more intelligent way of resolving merge issues.
Which Git extension is specifically designed for handling large files?
- Git LFS (Large File Storage)
- Git Large Files Extension
- Git BigFiles
- Git HugeStorage
Git LFS (Large File Storage) is a Git extension designed to handle large files efficiently. It replaces large files with text pointers in the Git repository while storing the actual files on a remote server.
Which command is used to undo a commit that has not been pushed to the remote repository?
- git reset --soft HEAD^
- git revert HEAD
- git reset --hard HEAD^
- git reset HEAD^
The correct option, git reset --hard HEAD^, is used to undo the last commit completely. It discards changes and moves the HEAD pointer to the previous commit. git reset --soft HEAD^ preserves changes, git revert HEAD creates a new commit to undo changes, and git reset HEAD^ is for unstaging.
