Solution - Linux Commands Hackercise

The solution to the hackercise is given below, but we highly recommend that you try to 'hack' and solve it with the knowledge of Linux Commands that you have gained. If you are stuck, you can obviously look at the command(s) to run, but first try on your own.

Let us start by finding out where we are by using the Print Working Directory command.
pwd
You will find out that you are in the / directory.

Now let us list the contents of this / directory using the list command.
ls You notice that there is a file called starting_scroll in that directory along with many other directories as shown below. bin dev home lib64 mnt proc run srv sys training_hall var boot etc lib media opt root sbin starting_scroll tmp usr

That looks like a good starting point. Let us read the contents of that file using the cat command as shown below. cat starting_scroll When you read the contents of the starting_scroll, you will see a welcome message (as shown below) with the objective of this hackercise, which is to find the legendary Linux Command Dragon scroll. The message also instructs you to start by first locating Tiger. Welcome to the Cyber Dragon Warrior Linux Command Hackercise! You are the Dragon Warrior and the only way to unlock your full potential is by finding the Legendary Linux Command Dragon Scroll. You might want to start by locating Tiger. She knows where the Dragon Scroll is kept, but she may not be to happy to see you.

Let us try and find out where Tiger is by using the locate command. locate Tiger You will see the following message displayed on the screen locate: warning: database '/var/cache/locate/locatedb' is more than 8 days old (actual age is 17.8 days) /home/Tiger /home/Tiger/message_from_tiger You may see a warning message saying that the locatedb database has not been updated in the past 8 days. You can safely ignore this warning. You will also see that the Tiger directory is in the /home directory and inside that Tiger directory is a file named message_from_tiger.
