Cheat sheets
Status: 🟩 COMPLETE Last updated: 2026-06-21 Plain-English tagline: Quick reference cards for the CLI tools you use every day. The textbook entries explain why; the cheat sheets give you what to type.
What these are
A cheat sheet is the commands grouped by what you’re trying to do, with a one-liner each. No long prose. No deep theory. The mental model already lives in the corresponding textbook entry; this is the daily-use surface.
Reach for a cheat sheet when:
- You know what you want to do but forgot the exact command
- You want a one-screen reference open while you work
- You’re teaching someone else and want a printable handout
Reach for the textbook entry when:
- You want to understand why a thing works the way it does
- You hit a gotcha that needs context
- You’re learning the tool for the first time

How to use these
Skim, then keep one open. A cheat sheet is most useful as a side panel while you work, not something you read end-to-end. Bookmark the one for the tool you use most.
Pair with the textbook. If a command surprises you (“wait, why does it do that?”), click through to the textbook entry. The cheat sheet gives you the trigger; the textbook gives you the reason.
Trust the gotchas. Each sheet has a short gotchas section near the end. These are the genuinely surprising things — read them once, save yourself time later.
What’s NOT here
The cheat sheets cover command-line tools. There’s no cheat sheet for:
- React / Next.js / Tailwind syntax — these aren’t really cheat-sheet-shaped (they’re whole programming languages, not lookup tables). The textbook entries cover them properly.
- SQL syntax — covered in SQL the language 🟩.
- Claude Code slash commands — your installed plugins decide what’s available; check
/helpin a live session.
