Cheat sheets

CHEAT SHEETS · WE ATTEMPT TO TEST ON ALL VERSIONS

One page per tool: the commands and keys worth keeping in one place, grouped by what you are trying to do, with a sentence on each group, the gotchas, and links to the official docs.

Each sheet names the version of the official documentation it was checked against. Where this site’s own configs change a default, the sheet says so and links to the config. Where the site has a tutorial for the tool, the sheet links to it.
