Githug is an awesome program to help you improve your git skills. It contains several levels, that start off with some easy tasks and will go deeper with every level. At first, you start with initializing a bare git repo, adding and committing files, and configuring the
.gitignore file. But then you get to remote repositories, stashing, rebasing, merging, and reflogs. I found it very useful, to improve my knowledge about git and found myself reading the man files more often, getting to know some awesome details about git.
Githug is written in Ruby and maintained on Github. There are more levels to come, so this blog will be updated continuously. If you find any errors or missing levels, feel free to comment below.
Githug requires Ruby 1.8.7 or higher. You can check which version of Ruby is installed with the following command:
If ruby is not installed, follow the installation instructions on ruby-lang.org.
Once you have installed Ruby, you're good to install Githug. To install it, run the command:
gem install githug
If you get a complaint about permissions, you can rerun the command with
sudo gem install githug
After Githug is installed, change the directory to the location where you want the game-related assets to be stored. Then run
You will be prompted to create a directory.
No githug directory found, do you wish to create one? [yn]
y (yes) to continue,
n (no) to cancel and quit Githug.
Githug has 4 game commands:
githug play- The default command, checks your solution for the current level
githug hint- Gives you a hint (if available) for the current level
githug reset- Reset the current level or reset the level to a given name or path
githug levels- List all the levels
As I had some trouble myself with some of those levels, I thought, that it might be helpful for other people to find a solution to the levels. I decided to make my solutions available, hoping they might help you. My approach to solving the levels might differ from your approach, but that’s the beauty of such problems. There often isn’t this one way to get things done. But without any further ado, here’s my solution.
Note: Please do not go to the solution directly. First try yourself!
Make sure you move into the git_hug directory created by Githug to continue with the game.
Level 1: init
A new directory,
git_hug, has been created; initialize an empty repository in it.
Level 2: config
Set up your git name and email, this is important so that your commits can be identified.
git config --global user.name "Ashutosh Krishna" git config --global user.email "email@example.com"
Level 3: add
There is a file in your folder called
README, you should add it to your staging area
Note: You start each level with a new repo. Don't look for files from the previous one.
git add README
Level 4: commit
README file has been added to your staging area, now commit it.
Make sure, your branch at this stage is master. If it's not, change your branch to master using the command:
git checkout -b master
After the branch has been changed to master, here's the solution:
git commit -m "Add README"
Level 5: clone
Clone the repository at https://github.com/Gazler/cloneme.
git clone https://github.com/Gazler/cloneme
Level 6: clone_to_folder
Clone the repository at https://github.com/Gazler/cloneme to
git clone https://github.com/Gazler/cloneme my_cloned_repo
Level 7: ignore
The text editor 'vim' creates files ending in
.swp (swap files) for all files that are currently open. We don't want them creeping into the repository. Make this repository ignore those swap files which are ending in
This opens the 'vim' editor. Press I to Insert Text and add the following in the
To save and exit, press the Esc key and type :wq, and press Enter.
Level 8: include
Notice a few files with the '.a' extension. We want git to ignore all but the 'lib.a' file.
Add the following in the .gitignore file:
Level 9: status
There are some files in this repository, and one of the files is untracked, which file is it?
Level 10: number_of_files_committed
There are some files in this repository, how many of the files will be committed?
Level 11: rm
A file has been removed from the working tree, however, the file was not removed from the repository. Find out what this file was and remove it.
git status git rm deleteme.rb
Level 12: rm_cached
A file has accidentally been added to your staging area, find out which file and remove it from the staging area.
NOTE: Do not remove the file from the file system, only from git.
git status git rm --cached deleteme.rb
Level 13: stash
You've made some changes and want to work on them later. You should save them, but don't commit them.
Level 14: rename
We have a file called
oldfile.txt. We want to rename it to
newfile.txt and stage this change.
git mv oldfile.txt newfile.txt git add newfile.txt
Level 15: restructure
You added some files to your repository, but now realize that your project needs to be restructured. Make a new folder named
src and using Git move all of the .html files into this folder.
mkdir src git mv *.html src
Level 16: log
You will be asked for the hash of the most recent commit. You will need to investigate the logs of the repository for this.
I hope you had a fun time learning Git with Githug.
