Adding Grep and Find commands

[Legedith]

I like the idea of using grep for searching files for keys. I have previously implemented this where a user had to grep through a log file for a phrase which would reveal an ascii art item.

find would be a valuable tool to have as well. Could look at creating a specific file within a subdirectory such as .hidden.key that the player would need to locate with something like:

find . -type f -name "*.key"

The specific scenario could be something along the lines of:

You have entered a room. There is a door on the opposite side, which is locked.
You must find the key to advance forward. Use 'ls' to see what's in the room.

When the user enters the room the game can create a number of directories:

chest
book
chest of drawers
...
etc

The hidden.key can be added to one of the directories to be found. It can then contain a message that can be cat'd out to reveal the next step forward.

Thank you for assigning the above to me. I will get working on this later on today!

@Legedith - I have created PR #4 - for the time being I've implemented the OS check we discussed in the initial issue as well as removed the ASCII art from the main file as I was finding the readability difficult to follow in order to add the new features discussed. I aim to continue working on implementing the grep and find in the coming days, I think the greater challenge is creating the story arch to add it in.

This evenings work was mostly in order to improve the readability of the code and help with maintaining

Just merged the PR. if you want, we can brainstorm ideas for the story arch too.

Thank you! I've got a couple of ideas, re-reading the existing story line to see how it will best fit. Did you have an idea as to whether you wanted to have grep or find in basics or the good stuff arch?

[Legedith]

I think they should go into the good stuff arch
