Tip checklist (authorized only)

  1. Confirm you may process the YAML (lab VM / your build / courseware).
  2. Record path, hash, expression sketch, and output shape in Evidence.
  3. Process only a short syllabus set — avoid unbounded dumps.
  4. Quote a few queried fields; redact secrets.
  5. Note yq version/flavor so Evidence stays reproducible.
  6. Optional: rewrite safely with sponge-moreutils-tips.
  7. Optional: bound long runs with timeout-cmd-tips.
  8. Redact secrets, cookies, tokens, and home-directory paths before sharing.

Allowed framing

  • Classroom queries on student-written YAML fixtures you control.
  • Binding hash + expression sketch + short output quote.
  • Documenting "parse error / null" as valid lab outcomes.
  • Comparing yq ↔ jq under one binder.

Scope we will not cover

  • No crack/pirate/keygen of commercial apps via yq.
  • No scraping / exploit / ASLR-bypass PoCs via yq.
  • No credential-theft via YAML queries.
  • No unauthorized processing of third-party production data.

Beginner path (authorized only)

  1. Obtain one syllabus-approved YAML file you control.
  2. Run a short expression; quote output.
  3. Hash + note expression; bind Evidence.
  4. Optional: compare with a jq filter on JSON.
  5. Stop at literacy — no exploit cookbooks.
Which to pick
  • Prefer authorized, short-expression, redacted Evidence.
  • Use jq / sponge / timeout peers when the syllabus asks.
  • No exploit, crack, or credential-theft framing.

FAQ

What is a "yq yaml tip" page in BinBench framing?

A checklist for querying authorized YAML you own — not a cookbook for scraping secrets from hosts you do not control.

How does this differ from jq-filter-tips?

jq-filter-tips covers JSON. This page zooms on yq Evidence habits — it does not overwrite that page.

Can I yq configs I do not own to steal credentials?

No. Authorization first. BinBench will not publish crack/bypass or credential-theft recipes.

Does this teach exploit / scraping / bypass PoCs via yq?

No. Mentions of exploit/bypass appear only as refusals. Authorized yq literacy only.

Does this teach credential theft via YAML queries?

No. Redact secrets, tokens, and PII in Evidence before sharing.
