14 – strings
Navigate to the folder
the file was executable so I ran it to see what would happen, as expected it a file with sting in loop.
Reloaded the the shell terminal navigated to the file
strings | grep CTF
Gave that a shot to see search the file with grep for CTF and nothing returned in a reasonable amount of time so restarted.
after a couple of different trial and errors I got this to work
strings strings | grep CTF
