Git Git Staging and Commits

Question 1

What is the staging area (index) in Git?

Accepted Answer

An intermediate area where changes are prepared before being committed

Answer

The staging area (also called the index) holds a snapshot of changes you have marked to be included in the next commit.

Question 2

Which command stages only specific hunks of a modified file interactively?

Accepted Answer

git add -p <file>

Answer

The `git add -p` (patch) command interactively presents each change hunk and lets you choose whether to stage it.

Question 3

What does `git commit --amend` do?

Accepted Answer

Modifies the most recent commit by adding staged changes or editing its message

Answer

The `--amend` flag replaces the most recent commit with a new one that includes any newly staged changes and an optionally updated message.

Question 4

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

Accepted Answer

Automatically stages all tracked modified files and commits them

Answer

The `-a` flag automatically stages all modifications and deletions to tracked files before committing, skipping the need for explicit `git add`.

Question 5

How do you unstage a file that was added with `git add`?

Accepted Answer

git restore --staged <file>

Answer

The `git restore --staged <file>` command removes the file from the staging area without discarding the working directory changes.
