Implement more utility commands like cat, mkdir etc...

[29jm]

On top of my head, the following are missing and could be implemented with the functions available in the libc right now:

• cat
• cd (this one should be implemented in the terminal app, not as a standalone program)
• tree (in fact it's already implemented in test.c, but not in a useful form)
• rm
• grep

I will give a shot at cat and rm might make for a fun challenge

@octetd actually I added a basic cat a few commits ago, but it doesn't support multiple files, e.g. cat file1 file2, maybe you could add that? As for rm I added an unlink program that literally just calls unlink (the system call), but It'd be cool to have a more proper rm, with support for its -r option.

The current unlink system call won't delete folders though, not even empty ones. I'll add an rmdir syscall, you can assume you have it (from unistd.h, see man 3 rmdir) in the mean time if you start before I push it.

I will hold on until you push that then and give priority to #15

I will try implementing cd.

Excellent, let me know if I can help with anything.
