Description:
Sometimes you need to handle process data outside of a file.
Can you find a way to keep the output from this program and search for the flag?
Connect to jupiter.challenges.picoctf.org 7480.
Hints:
1. Remember the flag format is picoCTF{XXXX}
2. What's a pipe? No not that kind of pipe... This kind
