This is a really nice idea! I played it a little bit and found one thing that can be confusing (at least for experienced Bash users): The use of <> as quotes. For instance:

   You can use the < head -n 1 > spell to take a peek at what a file holds

How about using a not-easily-typeable character pair like the guillemots?

> guillemots

May I suggest 「these」 instead?

Wow.

I'm adding this to my ascii "vocab"

[Hasnep]

They're CJK 「quotation marks」, so not actually ASCII

[dotancohen]

Why not the backtick? That's the standard in Markdown, and its actual use in bash is nearly eliminated with the far safer $() syntax.

I agree, I myself have doubts about using the chevrons as quotes. bashcrawl used * to show the commands you're supposed to type. You can imagine my confusion when I encountered that notion. Using «» is a good idea though, thank you.
