Question 1

What is the main advantage of `git rebase` over `git merge` for integrating changes?

Accepted Answer

Rebase produces a cleaner, linear commit history without merge commits

Answer

Rebasing replays commits on top of another branch, resulting in a linear history free of merge commits, which is easier to read and bisect.

Question 2

What does `git stash pop` do compared to `git stash apply`?

Accepted Answer

pop applies the stash and removes it from the stash list; apply applies it but keeps it

Answer

The `git stash pop` command applies the most recent stash entry and then drops it from the stash list, while `git stash apply` applies it without removing it.

Question 3

Which command applies a specific commit from another branch onto the current branch?

Accepted Answer

git cherry-pick <commit-hash>

Answer

The `git cherry-pick <commit-hash>` command applies the changes introduced by the specified commit onto the current branch as a new commit.

Question 4

What is a Git tag, and how does a lightweight tag differ from an annotated tag?

Accepted Answer

Tags mark important commits; lightweight is just a pointer while annotated stores extra metadata like tagger and message

Answer

A lightweight tag is merely a named reference to a commit, while an annotated tag is a full Git object containing the tagger's name, email, date, and a message.

Question 5

What does `git bisect` help you do?

Accepted Answer

Binary search through commit history to find the commit that introduced a bug

Answer

The `git bisect` command automates a binary search through commit history, allowing you to efficiently pinpoint which commit introduced a regression.
