• TODO: using the noun-verb grammar (https://irian.to/blogs/mastering-vim-grammar), systematically show the 7 different types of commands

• TODO: 2025-03-15 - add lots and lots and lots of examples like perl (https://catonmat.net/introduction-to-perl-one-liners). Start with g// and v// commands for example; or g- commands and z- commands; combos, not individual letters like cheat sheets and manpages do, the power is in composability.

  • Instead of giving the learner rules of how perl/vim/zsh works, give examples with redundancy. That will lead the learner to reverse engineer the rules. Making them derive the rules will automatically make them internalized which is what you want. Example based learning just neural networks
  • more like the zsh draft 2: https://gist.github.com/sarnobat/e648080b72bd50012a3ccde733079c3a
  • Not a grammar. But paths in the grammar.

• :2,10s/pick/squash/g

• :,10s/pick/squash/g

(draft 1) Obscure Shell Syntax

• Like irregular verbs in a foreign language, the most common primitives are optimized for brevity rather than consistency, so often are illogical and idiomatic (you have to "just memorize" them to get the benefit).
• --I'm organizing this by symbol rather than concept since there is a universal closed set of characters, but concepts have subjective implicit meaning (like key bindings)

$

• $'' - verbatim string, no interpretting (useful if you have filenames with non ASCII characters)

  • $"" - verbatim string, no interpretting (except locale)

ssh through an intermediate when the destination doesn't support ssh

(e.g. using antec) From host that doesn't have ssh:

autossh -M0 -p 222 -R 9001:localhost:22 sarnobat@host.personaldomain.com
