Graduation - The portable operating system

• It is lightweight and fast
• It can fit on any floppy disk
• It is portable, all of your programs can be in your inventory
• It has the same commands from CraftOS, just re-written from scratch. You do not lose any habits from CraftOS, and can be used by the majority of players.
• It is open-source, this mean that you can improve, share, copy and modify the code, and even create an operating system using this base (please read the section with the following URL:
https://github.com/R...ore-proceeding-)
• You can use it for rescuring infected computers.
• You can add your own programs.
• System API is really simple to understand.

return not s:find "[^\t ]" or #s == 0

return s:find "^[\t ]" or #s == 0

Looks kinda cool. The pdf manual is a neat idea although a markdown file in the wiki probably would've done just as well and been much easier to write. It's also not that hard to show folder file sizes in the 'ls' program, and that'd be pretty helpful. Also, what's with the 'rwx'? I'm guessing that's for file permissions (read/write/execute), but I couldn't find anything in the code that handles that. Is it just for show?

I looked through the code; you have a big function for finding if a string is empty, which I think should probably return true if it only contains "\t" and " ". You could simplify this to:

return not s:find "[^\t ]" or #s == 0

That being said, your current function will also return true if only the start is whitespace (probably unintentional?), which'd be this:

return s:find "^[\t ]" or #s == 0

You give quite a few restrictions in the README on creating OSs from this, but you've given it the MIT license. Have a read through your restrictions and the license: the license says "do whatever you want", pretty much. You might want to change that.

If you can manage it, I'd add in things like piping: redirecting the output of one program to the input of another. Right now, this only really gives a graphical tweak to the inbuilt shell commands, so claiming it's "more powerful than a graphical operating system" is a bit risky when compared to something that does things like multitasking and users as well as fancy graphics.

Anyways, the effort you put into this really shows, just keep adding more to make it worth the annoyingly awkward installation process.

- The rwx is to short this, because it takes only 3 characters :

• Can I read ?
• Can I write ?

Sure but does it actually affect anything? Like, would I be able to give a file `r-x` permissions and then not be able to write to it (make it read-only)?

- I prefer writing on a document than on a Wiki. I do not really like the way Wikis works.


That may be true, but I'd suggest most people prefer wikis. It's probably as simple as copying the pdf text into a `.md` file and doing a bit of formatting, ~10 mins tops.
