Unix/Git Assignment

1)You have landed yourself an internship at Pied-Piper's core algorithm team. Your job as a tester is to ensure that the algorithm is correct. The first thing you'll need to do in order to start is to get access to the code base. Since it's the first day of your work, you will need to tell Git about yourself before you can start contributing. What are two Git commands that will set your name and email globally for your account?

2) If the source code for Pied-Piper's Middle-Out algorithm is located at https://git.piedpiper.com/algorithm/middle_out.git, what is a Git command that will obtain a local copy of the full repository?

3) After you've navigated to the project directory, what is a command that will show you the history of all commits to the repository, assuming no aliases have be configured for Git?

4) Turns out you do have some personalized preferences how you use Git. What is the file you can edit in order to set global configurations for Git to your likings?

5) To start on your own testing project, you want to make sure that the changes you make will not affect others, and therefore it is good practice to be working on a new branch altogether. What is a command (or commands) in Git that will allow you to switch to a new branch named 'testing'?

6) The tests are written in Java, and therefore will generate many .class files upon compilation. In order to keep the repository clean of files you don't wish to keep under version control, you want to tell Git not to include any .class files into your repository. Which file tells Git the file patterns such that Git will not monitor any changes to those files?

7) Assuming that the said file is empty, what modifications do you need to make in order for Git to ignore any '.class' file?

8) You've written your very first test named 'ShouldSortByD2F.java', what are the Git commands that will reflect your changes in the testing branch in the REMOTE repository named 'origin'?

9) Satisfied with what you did on the first day, you turned off your computer and went back home. Meanwhile, Gary, another member on your team, pushed some changes to the 'core' branch in the remote repository, which include new classes to be tested. What is a single Git command that will keep your current branch up-to-date with the changes made to the 'core' branch on the remote repository?

10) The previous command is effectively the same as sequentially executing which two Git commands?

We made some changes to fix a bug for ShouldSortByD2F.java and we now want to commit them. Hence, we enter:

git add ShouldSortByD2F.java

git commit -m fixed a bug with ShouldSortByD2F.java

Uh oh! We now realize that the fix was not a fix after all! It actually broke the program. We should have tested it before committing. However, you also know there is a git command to UNDO this commit. What is a single git command to undo the commit above?

12) You have now decided to work on your own new project. You are currently in your home directory, and you type

mkdir my_new_project

cd my_new_project

You decide you want to use git for version control on your project, what is the command to initialize your current directory into a new git repository?

13) You decide you want to host your repository on Github. You create a new repository on Github to house your local repository. Github gives you a remote URL of https://github.com/Gary/my_cool_project.git.

What is a command to link your local repository with your new remote repository? Name this remote repository my_new_remote.

14) You realize the name my_new_remote is a strange name for a remote repo, and you decide you want to rename it to origin.What is a single command to rename your remote from "mynewremote" to origin?

15) You have created a README.md for your project and decide you want to add it to your remote repository, first we must add the file to the staging area.What is a command to add the file README.md to the staging area?

16) Excellent! You decide you are ready to make your first commit, what is a single command to make a commit with the commit message of "added a readme"?

17) Lastly, you are satisfied with your changes and you decide you want to push to the remote repository. Recall the name of our remote was origin. The branch we want to push to is the master branch. What is one command to push your commit to the master branch of your remote repository named origin?

18) We now want to tag the current commit as final so that we can refer to it easily in the future. What is one command that will set the tag for the current commit as final?

19) What is one command that will list all the available tags for the current git repository?

20) Which directory stores all the data necessary for git to keep track of your project and its history?

A) .gitignore B) .git C) .vimrc D) .gitlogs E) .gitrc
