Bandit Level 8 To 9

Level 8 -> 9

Game Instructions

The password for the next level is stored in the file data.txt and is the only line of text that occurs only once

Let’s ssh into the next game:

ssh -p 2220 bandit8@bandit.labs.overthewire.org
password: cvX2JJa4CFALtqS87jk27qwqGhBM9plV

This one seems more difficult but really isn’t… Let’s see what we need to do to find this file:

1. We need to sort all of the lines in the file
2. We then need to find out which one of these lines is unique

We’ll use something called Piping | here.

sort data.txt | uniq -u

The above like uses the sort command to sort all lines, then uses uniq with the flag -u to find the only unique line.

Done and done… we just found that password… no big deal.
