Problem: During your adventure, you will likely encounter a situation where you need to process data that you receive over the network rather than through a file. Can you find a way to save the output from this program and search for the flag? Connect with 2018shell.picoctf.com 2015.
Solution:
Using nc connect to the server.
nc 2018shell.picoctf.com 2015
What we get is never ending text and not the flag so using the pipe command we can search for the flag.
Using the pipe ( | ) command, we can chain the commands of using nc to connect to the server and grep to find the string, we can get the flag.
nc 2018shell.picoctf.com 2015 | grep pico
