Example:
git add .
15. What is git commit?
Answer
Stores staged changes in repository history.
Example:
git commit -m "Bug fix"
16. What is git push?
Answer
Uploads local commits to remote repository.
Example:
git push origin main
17. What is git pull?
Answer
Downloads and merges changes from remote repository.
Example:
git pull origin main
18. What is git fetch?
Answer
Downloads changes without merging.
Safer than pull when reviewing updates.
19. Difference Between Pull and Fetch
Answer
git pull | git fetch |
|---|---|
Fetch + Merge | Fetch Only |
Updates Working Tree | No Merge |
20. What is git log?
Answer
Displays commit history.
Example:
git log
Branching & Merging
21. What is a Branch?
Answer
A branch is an independent line of development.
Allows developers to work without affecting the main codebase.
22. Why Use Branches?
Answer
Benefits:
Feature development
Bug fixes
Experimentation
23. What is the Main Branch?
Answer
Primary branch of the repository.
Common names:
main
master
24. What is git checkout?
Answer
Switches branches.
Example:
git checkout feature-login
25. What is git switch?
Answer
Modern alternative to checkout.
Example:
git switch develop
26. What is Merging?
Answer
Combines changes from one branch into another.
Example:
git merge feature-login
27. What is a Merge Conflict?
Answer
Occurs when Git cannot automatically combine changes.
Usually happens when multiple developers modify the same code.
28. How Do You Resolve Merge Conflicts?
Answer
Steps:
Identify conflicting files
