Linux and Git

For this task, you have to follow the instructions below and find the password to Secret-Scroll.pdf.

Note: All the tasks given below should be strictly implemented using Ubuntu terminal commands only.

1. Clone this GitHub repository to your device using git clone https://github.com/gauthamk02/TerminalHunt.git

2. Create a new directory in the same repository named solution.

3. The password has four different parts which will be found in different steps. For the first part, solve the questions below and save the answer in a file named part1.txt in the solution directory.

   • i. Multiply the smallest perfect number by 44
   • ii. Find the element with atomic mass equal to the previous number.
   • iii. Write the atomic number of that element in the file part1.txt.

4. The second part of the password is stored in a file which you need to find by using the below hints.

   • i. Find the HCF of 336 and 702 and navigate to that numbered folder.
   • ii. From that, copy the file with the name which is the fourth digit of Pi into the solution directory.
   • iii. Now rename the file as part2.txt.

5. You are halfway there💫, now let's start with a few git commands. For the next part of the password, the hint to find it is there in the commit log of the repository. Find the file and copy it to the solution directory. Dont forget to rename the file to part3.txt.

6. Commit the work that you did till now to the main branch.

7. The file containing the fourth and last part of the password is present on a different branch😱. Don't worry we’ll help you with this one 😊. Run the command git branch -a to see all the local and remote branches of the repository. Type git checkout <branch_name> in the terminal to switch to the new branch where <branch_name> is the name of the largest continent. This will create a local copy of that branch and switch to it.

8. Cool, now that you are in the new branch, let's find the file 🔍. For that, you can use the command find . -name <file_name>.txt where <file_name> is the name of the city named after the Goddess of War from Greek mythology.

9. Since we found the last file, let's combine all of them to find the password🥱. But wait, the solution directory is in the main branch and it doesn't have the folder with the last file🗿. That's where merging comes in. This branch can be merged with main and the folder with the last file will be available on the main branch. First, go back to main branch using the command git checkout main and for merging the branch with the file into main use git merge <branch_name> where <branch_name> is the name of the branch with the file. Now, copy the file <file-name>.txt into the solution directory and rename it to part4.txt.

10. Finally, all the parts of the password are in one place. Now we just need to combine them to get the password and store it in a new file called password.txt. Navigate to the solutions folder and concatenate all the contents of the file into a text file called password.txt. After concatenating delete all the files except password.txt.

11. Congrats🎉, you can now open the protected PDF with the password you found. Remove any space/new-line characters from the text in password.txt and use it to open the PDF. For the final part of the task, create a SOLUTION.md file in your amfoss-tasks task directory and write detailed terminal commands which you have used in each step and keep the screenshot image of the PDF at the end of the file. Also, write the Git terminal commands that you will use to push all your work to your amfoss-tasks GitHub repository.
