Tip checklist (authorized only)

  1. Confirm you may create temps on the host (lab VM / your sample / courseware).
  2. Prefer mktemp / mktemp -d / mktemp -t lab.XXXXXX over hard-coded /tmp/foo.
  3. Record -d/-t/-p flags and template you actually used.
  4. Quote the created path Evidence; redact usernames if policy requires; remove after lab.
  5. Optional: type the temp → file-cmd-tips; fill with seq → seq-tips.
  6. Optional: flush → sync-tips; keep a copy → tee-tips.
  7. Optional: dump sample → od-tips.
  8. Redact sensitive labels; never leave secrets in temps.

Allowed framing

  • Classroom labs creating a safe temp file/dir for a syllabus script.
  • Binding -d/-t settings as Evidence.
  • Documenting "mktemp not installed / permission denied" as valid lab outcomes.
  • Comparing mktemp ↔ file / seq under one binder.

Scope we will not cover

  • No crack/pirate/keygen via mktemp.
  • No race exploit / unauthorized-access / bypass PoCs via predictable temps.
  • No credential-theft via temp dumps.
  • No intentional mktemp abuse against hosts you do not own.

Beginner path (authorized only)

  1. Obtain one syllabus-approved lab VM you control.
  2. Run t=$(mktemp); echo lab > "$t"; cat "$t"; rm -f "$t"; quote success.
  3. Bind template notes as Evidence; redact sensitive labels.
  4. Optional: compare with file-cmd-tips.
  5. Stop at literacy — no temp cookbooks against others.
Which to pick
  • Prefer authorized, cleaned-up, redacted Evidence.
  • Use file / seq / sync peers when the syllabus asks.
  • No exploit, crack, or unauthorized-access framing.

For legal, authorized and educational use only.

FAQ

What is a "mktemp tip" page in BinBench framing?

A checklist for creating authorized temporary paths on hosts you own — not a cookbook for writing into directories you do not control.

How does this relate to file-cmd-tips?

file-cmd-tips covers type labels. This page zooms on mktemp path Evidence — it does not overwrite that page.

Can I mktemp into other users\' production dirs I do not administer?

No. Authorization first. BinBench will not publish unauthorized-access recipes.

Does this teach exploit / race PoCs via predictable temps?

No. Mentions of exploit appear only as refusals. Prefer mktemp over hand-rolled /tmp/foo names.

Does this teach credential theft via temp dumps?

No. Never write secrets into demos; clean up lab temps.
