Top 100 GIT Questions and Answers
1.What is Git, and how does it differ from other version control systems?
Git is a distributed version control system used to track changes in source code during software development. It differs from other version control systems like Subversion and CVS in that it doesn’t rely on a central repository. Instead, every developer has a full copy of the repository on their local machine, allowing for faster branching and merging.
2. What is ‘staging area’ or ‘index’ in Git?
3. What are the advantages of using Git for software development?
Git offers several advantages for software development, including:
- Distributed development: Developers can work independently and merge their changes later.
- Easy branching and merging: Branching and merging in Git is fast and efficient, allowing developers to experiment with different features and easily incorporate changes into the main codebase.
- Version control: Git tracks every change made to the codebase, making it easy to roll back to a previous version if needed.
- Collaboration: Git makes it easy for multiple developers to work on the same project simultaneously and track their changes.
- Open source: Git is open source, meaning that anyone can contribute to its development and use it for free.
4. What is the Git workflow, and how does it work?
The Git workflow is a series of steps that developers follow to make changes to the codebase. It typically involves creating a branch, making changes, committing those changes, and then merging the branch back into the main codebase. The workflow can be customized to fit the needs of a specific project, but the basic idea remains the same.
5. What is a commit in Git, and how is it used?
A commit in Git is a snapshot of changes made to the codebase. It is used to track changes, roll back to a previous version, and collaborate with other developers. Each commit has a unique identifier and a commit message, which describes the changes made in that commit.
6. Why do we not call git “pull request” as “push request”?
- “Push request” is termed so because it is done when the target repository requests us to push our changes to it.
- “Pull request” is named as such due to the fact that the repo requests the target repository to grab (or pull) the changes from it.
7. What is a branch in Git, and how does it work?
A branch in Git is a separate version of the codebase that allows developers to experiment with new features or make changes without affecting the main codebase. Branches can be merged back into the main codebase when the changes are ready.
8. What is a remote in Git, and how does it work?
A remote in Git is a copy of the repository that is stored on a different server. It allows developers to collaborate with other team members and pull changes made to the codebase.
9. What is a merge in Git, and how does it work?
A merge in Git is the process of combining changes from one branch into another. It is used to incorporate changes made by multiple developers into the main codebase.
10. What is a conflict?
Git usually handles feature merges automatically but sometimes while working in a team environment, there might be cases of conflicts such as:
- When two separate branches have changes to the same line in a file
- A file is deleted in one branch but has been modified in the other.
11. What is a pull request in Git, and how is it used?
A pull request in Git is a way for developers to submit changes to the main codebase. It allows other team members to review the changes before they are merged into the codebase.
12. What is a fork in Git, and how is it different from a clone?
A fork in Git is a copy of a repository that is stored on a different user’s account. It allows developers to make changes to the codebase without affecting the original repository. A clone, on the other hand, is a copy of the repository stored on the same user’s machine
13. How do you create a new repository in Git?
