Thanks for the feedback. I was trying to make it work on mobile but maybe I didn't test it well in the end.

As for a sample, I will go and try to make something now. Thanks.

One nit: ^D only exits if the cursor is at the beginning of a line. Enter <space>^D and the session remains.

Otherwise, looks good! Use of "env" and proper quoting are strong signals!

"one or multiple" is + not *. The regex above will also match "h" and "help" without - character(s).

I agree with all this. I'm on Firefox android, pixel, lose part of the screen too.

I'd love to read a table of contents. I don't want to rip you off with zero dollars!

Anyway, sounds like a great book. Congratulations on completing and "shipping"!

Ah okay, I really wasn't aware. Thanks for reporting.

I am also seeing text off the screen using Brave on Android.

You are right. It is wrong, will need to look into this.

These two tweaks should improve it (by preventing the largest text and book graphic from overflowing the viewport horizontally on some smaller screen sizes):

Also, I really like what I see in your book so far and I am already learning things on the first few pages. Thanks!
