Level Goal
The password for the next level is stored in the file data.txt in one of the few human-readable strings, beginning with several ‘=’ characters.

Commands you may need to solve this level: grep, sort, uniq, strings, base64, tr, tar, gzip, bzip2, xxd

If we do an ‘ls -la’ we can see the files in the home directory.There is a file data.txt, if we cat this file we get a weird looking output, because the file is probably not human readable.

Lets use the command strings to see what we get as output.
strings data.txt

We can see the line starting with === and the password next to it. But lets get a cleaner output by using grep.
strings data.txt | grep =="

Now we see a few lines with the password in it.

there is the password.
