Solution
From the question, we understand that at this level we are going to be working with Git. Before we clone the repository let’s make a folder in the /tmp directory as from some of the previous levels we know we only have proper permissions to save files in the /tmp folder.

bandit30@bandit:~$ cd /tmp/
bandit30@bandit:/tmp$ mkdir git_level30
bandit30@bandit:/tmp$ cd git_level30
bandit30@bandit:/tmp/git_level30$
Now that we have created our working directory let’s clone the repository.
The password for the repository is the same as bandit30

Password: 5b90576bedb2cc04c86a9e924ce42faf
Now that we have the repository cloned to our machine. Let us see what files are present in the repository.
We see that there is a file called “README.md” in the folder. Let us have a look at the contents of this file.
Note: The .git directory found in the repository is created by git that consists of files that are required for the proper functioning of the features that are provided by git.

bandit30@bandit:/tmp/git_level30/repo$ cat README.md
just an epmty file... muahaha
Looks like the file is empty and we are not given any clue this time. Let us see if there are branches that are available in this repository.

bandit30@bandit:/tmp/git_level30/repo$ git branch -a
* master
remotes/origin/HEAD -> origin/master
remotes/origin/master
Looking at the branches we again don’t find anything useful.
Git has another feature called tags. They are used to mark specific points in the version history of the repository that is important. Let us see if we can find any clues looking at them.

bandit30@bandit:/tmp/git_level30/repo$ git tag

We see that we have a tag that is called “secret”. Let us view its contents
