Tip checklist (authorized only)

  1. Confirm you may resolve the path on the host (lab VM / your sample / courseware).
  2. Prefer realpath -e FILE / realpath -m REL short resolves over dumping entire trees.
  3. Record flags (-e / -m / -s) and input you actually used.
  4. Quote the canonical path Evidence; never paste secrets or private homes.
  5. If you need component splits, cross-check dirname-basename-tips.
  6. Optional: command location → which-command-tips / type-builtin-tips.
  7. Optional: name discovery → find-name-tips; keep a copy → tee-pipe-tips.
  8. Redact hostnames and sensitive path labels before sharing.

Allowed framing

  • Classroom labs canonicalizing paths in a dataset you own.
  • Binding -e / -m settings as Evidence.
  • Documenting "realpath not installed / no such file" as valid lab outcomes.
  • Comparing realpath ↔ dirname/basename under one binder.

Scope we will not cover

  • No crack/pirate/keygen via realpath.
  • No symlink-escape / unauthorized-access / bypass PoCs.
  • No credential-theft via resolving secret-bearing paths for exfil.
  • No intentional mass realpath enumeration against hosts you do not own.

Beginner path (authorized only)

  1. Obtain one syllabus-approved lab VM you control.
  2. Run realpath -e . on a sample directory you own; quote the path.
  3. Bind flags as Evidence; redact sensitive labels.
  4. Optional: compare with dirname-basename-tips.
  5. Stop at literacy — no escape cookbooks.
Which to pick
  • Prefer authorized, short, redacted Evidence.
  • Use dirname/basename / which / find peers when the syllabus asks.
  • No exploit, crack, or unauthorized-access framing.

FAQ

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

A checklist for resolving authorized paths to canonical forms on hosts you own — not a cookbook for probing paths you may not access.

How does this relate to dirname-basename-tips?

dirname-basename-tips covers path splits. This page zooms on realpath resolve Evidence — it does not overwrite that page.

Can I realpath other users\' private trees I do not administer?

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

Does this teach exploit / symlink-escape PoCs?

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

Does this teach credential theft via resolved secret paths?

No. Redact home directories and secret-looking filenames before sharing.
