Tip checklist (authorized only)

  1. Confirm you may name the path (lab VM / your sample / courseware temp).
  2. Prefer realpath PATH / realpath -s PATH on syllabus paths.
  3. Record resolved absolute path; quote short Evidence.
  4. Optional: deeper resolve → realpath-resolve-tips; symlink → readlink-tips.
  5. Optional: command location → which-tips; builtin → type-tips.
  6. Optional: parent → dirname-tips.
  7. Redact home/user path prefixes before sharing.
  8. Stop at literacy — no unauthorized path-recon cookbooks.

Allowed framing

  • Classroom labs resolving syllabus relative paths.
  • Binding realpath notes as Evidence.
  • Documenting "No such file" as a valid lab outcome.
  • Comparing realpath ↔ readlink under one binder.

Scope we will not cover

  • No crack/pirate/keygen via realpath.
  • No exploit / bypass / unauthorized-access PoCs.
  • No credential-theft via path recon.
  • No intentional realpath against foreign private trees as a recon target.

Beginner path (authorized only)

  1. Obtain one syllabus-approved lab VM you control.
  2. Run realpath .; quote success.
  3. Bind realpath notes as Evidence; redact sensitive labels.
  4. Optional: compare with readlink-tips / realpath-resolve-tips.
  5. Stop at literacy — no recon cookbooks for foreign trees.
Which to pick
  • Prefer authorized, redacted Evidence.
  • Use realpath-resolve-tips / peer tip pages when the syllabus asks.
  • No exploit, crack, or unauthorized-access framing.

FAQ

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

A checklist for sampling authorized path-resolve literacy on hosts you own — not a cookbook for hosts you do not control.

How does this relate to realpath-resolve-tips?

realpath-resolve-tips covers deeper resolve lanes. This page zooms on a compact realpath tip checklist — it does not overwrite that page.

Can I use realpath on other users\' production hosts I do not administer?

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

Does this teach exploit / bypass PoCs via realpath?

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

Does this teach credential theft via realpath tricks?

No. Redact tokens, secrets, and PII before sharing excerpts.
