Tip checklist (authorized only)

  1. Confirm you may handle the path strings on the host (lab VM / your sample / courseware).
  2. Prefer dirname '/a/b/c.txt' / basename '/a/b/c.txt' .txt over dumping entire directory trees.
  3. Record which utility, input path, and any suffix strip you actually used.
  4. Quote short split Evidence; never paste secrets or private home paths.
  5. If you need canonical paths, cross-check realpath-resolve-tips.
  6. Optional: command location → which-command-tips / type-builtin-tips.
  7. Optional: field glue → cut-fields-tips; name discovery → find-name-tips.
  8. Redact hostnames and sensitive path labels before sharing.

Allowed framing

  • Classroom labs splitting path components in a dataset you own.
  • Binding dirname/basename + suffix settings as Evidence.
  • Documenting "utility not installed / bad path" as valid lab outcomes.
  • Comparing dirname/basename ↔ realpath under one binder.

Scope we will not cover

  • No crack/pirate/keygen via dirname/basename.
  • No path-traversal / unauthorized-access / bypass PoCs.
  • No credential-theft via dumping secret-bearing paths.
  • No intentional mass path enumeration against hosts you do not own.

Beginner path (authorized only)

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

FAQ

What is a "dirname/basename tip" page in BinBench framing?

A checklist for splitting authorized path strings on hosts you own — not a cookbook for probing paths you may not access.

How does this relate to realpath-resolve-tips?

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

Can I dirname/basename other users\' private home paths I do not administer?

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

Does this teach exploit / path-traversal PoCs?

No. Mentions of exploit appear only as refusals. Authorized path-split literacy only.

Does this teach credential theft via path dumps?

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