- %OPTION% git --version
- %OPTION% git --option
- %OPTION% git --current



#### Q2. What command lets you create a connection between a local and remote repository?

- %OPTION% git remote add new
- %OPTION% git remote add origin
- %OPTION% git remote new origin
- %OPTION% git remote origin

[Reference](https://stackoverflow.com/questions/20291731/how-to-connect-to-a-remote-git-repository)



#### Q3. Describe what these Git commands do to the commit history:

```bash
git reset --hard HEAD~5
git merge --squash HEAD@{1}
```

- %OPTION% They reset the HEAD to the fifth commit in the repo, then merge to the master branch.
- %OPTION% The current branch's HEAD is reset back five commits, then prior commits are squashed into a single commit.
- %OPTION% They delete the last five commits.
- %OPTION% They merge the last five commits into a new branch.

**Explanation:**

- `git reset --hard HEAD~5` resets the current branch to the commit just before the last 5 (see `man gitrevisions` for details about this notation and other cool alternatives like `HEAD@{2 days ago}`). As it is a hard reset, it will also overwrite every change in the working tree as well. See `man git-reset`.
- `git merge --squash HEAD@{1}` HEAD@{1} is where the branch was just before the previous command (again, see `man gitrevisions`). This command sets the state of the index to be as it would just after a merge from that commit. This whole operation could be a way to take 5 commits from a branch in which you started a new feature and squash them to a single commit, a meaningful one.



#### Q4. Your current project has several branches; master, beta, and push-notifications. You've just finished the notification feature in the push-notification branch, and you want to commit it to beta branch. How can you accomplish this?

- %OPTION% Checkout the push-notifications branch and run git merge beta
- %OPTION% Checkout the master branch and run git merge beta -> push-notifications
- %OPTION% Delete the push-notifications branch and it will be committed to the master branch automatically
- %OPTION% Checkout the beta branch and run git merge push-notifications



#### Q5. Which of the following is true you when you use the following command?

`git add -A`

- %OPTION% All new and updated files are staged
- %OPTION% Files are staged in alphabetical order.
- %OPTION% All new files are staged
- %OPTION% Only updated files are staged



#### Q6. What will the following command print to the Terminal?

`git remote -v`

- %OPTION% A list of remote repositories and their URLs
- %OPTION% The current git version you're running
- %OPTION% An inline editor for modifying remote repositories
- %OPTION% The last 5 git versions you've installed



#### Q7. Looking at the following commands, describe what is happening.

```bash
git checkout feature-user-location
git cherry-pick kj2342134sdf090093f0sdgasdf99sdfo992mmmf9921231
```

- %OPTION% The commit is being tagged for release on the feature-user-location branch
- %OPTION% A commit is being copied from its original branch over to the feature-user-location branch
- %OPTION% The commit is being cherry picked as the new HEAD of the commit history
- %OPTION% A commit is being copied from the feature-user-location branch to the master branch
- %OPTION% The branch is switched to the feature-user-location branch, and the specified commit is applied to the branch.

**Explanation:** Commits aren't copied when cherry picking, they are cherry picked. The changes introduced by the commit are applied and a new commit is then created. This allow us to get specific changes as if they were patches (in the GIT's book, this is actually called [Patching](https://git-scm.com/book/en/v2/Appendix-C:-Git-Commands-Patching "See this in the GIT's book")). As a new commit is created upon feature-user-location, HEAD also changes to match it. You can see this in `cat .git/HEAD` and `cat .git/refs/heads/feature-user-location` for this case. See `man git-cherry-pick` for details.

**NOTE**: There are two versions of this question so far. The task is always "describe what is happening", the commands are always a `checkout` and a `cherry-pick`, and the correct answer is always the same.



#### Q8. What does the following command do to the git repository?

`git reset --soft HEAD^`

- %OPTION% It deletes all previous commits and reset the repository history back to its initial state.
- %OPTION% It resets the working branch to the first commit.
- %OPTION% It keeps the HEAD at the current commit, but clears all previous commits.
- %OPTION% It sets HEAD to the previous commit and leaves changes from the undone commit in the stage/index.



#### Q9. You find a bug in your project, but can't locate where it was introduced in the commit history. How would you diagnose this problem?

- %OPTION% Manually backtrack through your commit history.
- %OPTION% Use git search -diff to compare all commits in your repository history.
- %OPTION% Run a git rebase to find the buggy commit.
- %OPTION% Use git bisect to compare the buggy commit to an early commit that works as expected.



#### Q10. Why would the following command be used?

#### Q16. What files is this .gitignore programmed to leave out?

```shell
#.swift
build/

*.txt
*.metadata
```

- %OPTION% All files with a .swift, .txt, or metadata file extension, as well as the entire build directory
- %OPTION% Only the build directory
- %OPTION% All files in the build directory, as well as files ending with .txt or .metadata
- %OPTION% Only files with .swift and .txt extensions.

A line starting with `#` serves as a comment. Hence `# .swift` does not do anything. See `man gitignore`.



#### Q17. After you make changes to a local repository, you run the following command. What will this do?

`git commit -a -m "Refactor code base"`

- %OPTION% Nothing, you can't use multiple options in the same command

- %OPTION% Adds all modified files to the staging area, then commits them with a message



#### Q18. After checking your git status you get the following output, which shows the file beta-notes.js in the commit but also unstaged. How can this situation occur?

```shell
Change to be committed:

(use "git reset HEAD <file>..." to unstage)
modified: beta-notes.js
Changes not staged for commit:
(use "git add <file>..." to update what will be committed)
(use "git checkout --<file>..." to discard changes in working directory)

modified: beta-notes.js
```

- %OPTION% There were two copies of beta-notes.js but one was deleted
- %OPTION% beta-notes.js was staged, then modified afterwards, creating two different versions of the file
- %OPTION% Two copies of beta-notes.js were created, but only one is being tracked
- %OPTION% There are two tracked copies of beta-notes.js, but one was removed from the commit



#### Q19. Where are files stored before they are committed to the local repository?

  ```bash
  git pull -u origin master
  git reset --hard master
  ```
- %OPTION% ⠀
  ```bash
  git pull origin master
  git reset --hard origin/myCurrentBranch
  ```
- %OPTION% ⠀

  ```bash
  git fetch --all
  git reset --hard origin/master
  ```

- The command `pull` is `fetch` followed by either `merge` or `rebase` (in this case, `merge`). We don't want to merge. Merge would be an action to our **repository**. We just want to overwrite our **local files**.



#### Q21. Which statement is true when you use the git add -A command?
