Web Development Version Control 5

Question 1

What does `git reflog` provide that `git log` does not?

Accepted Answer

A history of all HEAD movements, including those from resets and checkouts

Answer

`git reflog` records every time HEAD has moved, making it possible to recover commits lost after a reset or branch deletion.

Question 2

What is 'trunk-based development'?

Accepted Answer

All developers commit frequently to a single main branch, with feature flags to hide incomplete work

Answer

Trunk-based development keeps the main branch always releasable by integrating small, frequent changes directly rather than long-lived branches.

Question 3

Which command renames a local Git branch?

Accepted Answer

git branch -m

Answer

`git branch -m` moves/renames a branch; when two names are provided it renames the old branch to the new name.

Question 4

What is the effect of `git commit --amend`?

Accepted Answer

Modifies the most recent commit, replacing it with a new commit that includes staged changes and/or a new message

Answer

`git commit --amend` rewrites the last commit with any newly staged changes and allows editing the commit message.

Question 5

What is a 'bare' Git repository?

Accepted Answer

A repository with no working directory, used as a central server-side repository

Answer

A bare repository stores only the Git data (like the `.git` folder) with no checked-out working tree, making it ideal for remote/server use.
