Aha [0], that is neat.

For the bar exam, I used a combination of an outliner and flashcards. Back then, I was usimg a PalmPilot. The idea was:

1. Turn the subject matter into a knowledge tree. 2. If a branch has more than 5 leaves, you split it up. 3. Flashcards are generated by traversing the tree. The parent node is the question, the child nodes are the answer.

The benefit of the tree is that it forces you to think about where in your structure a given piece of new information fits.

For CLIs - most reasonable commands either have a `-h`, `--help`, `-help`, `/?`, or what have you. And manpages exist. Hunt the verb isn't really a problem for CLIs.

And furthermore - aren't there shells that will give you the --help if you try to tab-complete certain commands? Obviously there's the issue of a lack of standardization for how command-line switches work, but broadly speaking it's not difficult to have a list of common (or even uncommon) commands and how their args work.

(spends a few minutes researching...)

This project evidently exists, and I think it's even fairly well supported in e.g. Debian-based systems: https://github.com/scop/bash-completion.
