task​

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

theory lil bit​

  1. sort: Sorts lines of text files. This is necessary because uniq only detects duplicate lines if they are adjacent (one after another).
  2. uniq -u: The uniq command filters out repeated lines. The -u flag specifically tells it to only print lines that are unique (lines that appear exactly once in the input).
  3. The Pipe (|): Used to send the sorted output of the file directly into the uniq command for filtering.

solution​

bandit8@bandit:~$ ls
data.txt
bandit8@bandit:~$ sort data.txt | uniq -u
