Help with Directories

[XDrew574X]

I need some help with the coding that I have, please.

I have to tell the console which directory I want to search in,
I have to search the directory for .txt files,
then I have to search the .txt for the words "I am a lawyer in * who has to find a lawyer overseas."

I am so lost. This is the coding I have so far. Can anyone please guide me??
Thanks in advance!
