Problem: Can you find the flag in file? This would be really tedious to look through manually, something tells me there is a better way. You can also find the file in /problems/first-grep_5_452e1c1630eb14b6753e9a155c3ae588 on the shell server.
File: THE_FILE
Solution: Login into the shell and navigate to the file or download the file. Once in the directory. Type: cat file | grep pico
Cat will print the contents of the file, but the file has a lot of text in it. So the best move is to use grep as the title of the problem implies. You use the | (pipe) to chain commands together.
