💻 Command Output

What is the output of git fetch origin?

You run git fetch origin in your local repository. What happens?

Git

git fetch origin

A It downloads new commits from the remote 'origin' but does not change your current branch.

B It deletes the local branch and replaces it with the remote branch.

C It downloads new commits and automatically merges them into your current branch.

D It pushes your local commits to the remote 'origin'.

💡 Hint

Think about whether your current branch changes after fetching.

git fetch downloads commits from the remote but does not merge them. Your current branch stays the same until you merge manually.

🧠 Conceptual

Which command downloads remote changes without merging?

You want to update your local repository with remote changes but keep your current branch unchanged. Which command should you use?

A git merge origin/main

B git push

C git fetch

D git pull

💡 Hint

One command downloads only, another downloads and merges.

git fetch downloads remote changes without merging. git pull downloads and merges.

🔀 Workflow

advanced

What is the correct workflow to update your local branch after git fetch?

After running git fetch origin, how do you update your current branch with the remote changes?

A Run <code>git push origin main</code> to update the remote branch.

B Run <code>git merge origin/main</code> to merge the fetched changes.

C Run <code>git pull origin main</code> immediately after fetch.

D Run <code>git reset --hard origin/main</code> to discard local changes.

💡 Hint

After fetching, merging is a separate step.

git fetch downloads changes. To update your branch, you merge the fetched remote branch into your current branch.

❓ Troubleshoot

advanced

Why does git fetch not change my files?

You ran git fetch origin but your files did not change. Why?

A Because <code>git fetch</code> only downloads changes but does not update your working files.

B Because you need to delete your local branch first.

C Because your local branch is behind and needs a <code>git push</code>.

D Because <code>git fetch</code> only works on new branches, not existing ones.

💡 Hint

Think about what git fetch does to your working directory.

git fetch downloads remote commits but does not change your working files or current branch until you merge or checkout.

✅ Best Practice

expert

What is the safest way to review remote changes before merging?

You want to see what changed on the remote before merging into your branch. Which sequence is best?

A Run <code>git reset --hard origin/main</code> to force update.

B Run <code>git pull</code> directly to update and review changes.

C Run <code>git merge origin/main</code> without fetching first.

D Run <code>git fetch</code>, then <code>git diff HEAD origin/main</code> to review changes, then merge if ready.

💡 Hint

Fetching first lets you see changes safely.

Fetching downloads remote changes without affecting your branch. Using git diff lets you review changes before merging.
