Tip checklist (authorized only)

  1. Confirm you may inspect PATH on the host (lab VM / your sample / courseware).
  2. Prefer which python3 / which -a ls short lookups over dumping entire PATH trees.
  3. Record command name and whether -a (all matches) was used.
  4. Quote the path Evidence; never paste secrets from adjacent env dumps.
  5. If you need shell builtin/alias resolution, cross-check type-builtin-tips.
  6. Optional: canonicalize → realpath-resolve-tips; split → dirname-basename-tips.
  7. Optional: PATH context → env-vars-tips; keep a copy → tee-pipe-tips.
  8. Redact hostnames and sensitive path labels before sharing.

Allowed framing

  • Classroom labs locating tools on a syllabus-approved VM.
  • Binding which / -a settings as Evidence.
  • Documenting "which not installed / command not found" as valid lab outcomes.
  • Comparing which ↔ type under one binder.

Scope we will not cover

  • No crack/pirate/keygen via which.
  • No PATH hijack / unauthorized-access / bypass PoCs.
  • No credential-theft via dumping private binary paths for abuse.
  • No intentional mass which enumeration against hosts you do not own.

Beginner path (authorized only)

  1. Obtain one syllabus-approved lab VM you control.
  2. Run which bash; quote the path.
  3. Bind notes as Evidence; redact sensitive labels.
  4. Optional: compare with type-builtin-tips.
  5. Stop at literacy — no hijack cookbooks.
Which to pick
  • Prefer authorized, short, redacted Evidence.
  • Use type / realpath / env peers when the syllabus asks.
  • No exploit, crack, or unauthorized-access framing.

FAQ

What is a "which command tip" page in BinBench framing?

A checklist for locating authorized executables on PATH on hosts you own — not a cookbook for probing other users\' private binaries.

How does this relate to type-builtin-tips?

type-builtin-tips covers shell type Evidence. This page zooms on which PATH lookup Evidence — it does not overwrite that page.

Can I which-scan other users\' production hosts I do not administer?

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

Does this teach exploit / PATH hijack PoCs?

No. Mentions of exploit appear only as refusals. Authorized lookup literacy only.

Does this teach credential theft via binary paths?

No. Redact sensitive home/bin paths before sharing.
