But I can't use the site consistently enough, because I don't feel comfortable having the browser open to their site during working hours when I am in front of screens.

Are there any terminal-based code camps? For example, Git repos that are designed as tutorials and can be cloned and run locally as CLI apps.

I've tried that tutorial with the Lynx browser, but rendering a web-tutorial in the terminal is not what I had in mind.

(As a side benefit, CLI tutorials would also be helpful for people to grep the basics of Unix-shells.)
