Last updated: · By the BinBench editorial team · Stars and releases checked via the GitHub API

time helps authorized labs record real/user/sys on commands they own. Pair with watch-interval-tips, timeout-cmd-tips, and nice-renice-tips.

Tip checklist (authorized only)

  1. Confirm you may time the command (lab VM / your build / courseware).
  2. Record command sketch, real/user/sys, and environment notes in Evidence.
  3. Prefer short syllabus commands — avoid secret-laden workloads in shared binders.
  4. Quote the three timing numbers; redact secret argv.
  5. Prefer /usr/bin/time when shell builtins differ.
  6. Optional: refresh with watch-interval-tips.
  7. Optional: bound with timeout-cmd-tips; priority with nice-renice-tips.
  8. Redact tokens, passwords, and home-directory paths before sharing.

Allowed framing

  • Classroom timing of student builds/fixtures.
  • Binding real/user/sys as Evidence.
  • Documenting "command not found / killed by timeout" as valid lab outcomes.
  • Comparing time ↔ watch ↔ timeout under one binder.

Scope we will not cover

  • No crack/pirate/keygen of commercial apps via time.
  • No exploit / side-channel / bypass PoCs via timing.
  • No credential-theft via timed secret commands.
  • No unauthorized timing of third-party production workloads.

Beginner path (authorized only)

  1. Obtain one syllabus-approved command you control.
  2. Run /usr/bin/time; quote real/user/sys.
  3. Bind sketch + timings as Evidence; redact secrets.
  4. Optional: compare under nice/timeout.
  5. Stop at literacy — no exploit cookbooks.
Which to pick
  • Prefer authorized, short-command, redacted Evidence.
  • Use watch / timeout / nice peers when the syllabus asks.
  • No exploit, crack, or credential-theft framing.

For legal, authorized and educational use only.

FAQ

What is a "time profile tip" page in BinBench framing?

A checklist for timing authorized commands on hosts you own — not a cookbook for benchmarking systems you do not control without permission.

How does this relate to watch-interval-tips and timeout-cmd-tips?

watch-interval-tips refreshes; timeout-cmd-tips bounds. This page zooms on time Evidence — it does not overwrite those pages.

Can I time unauthorized production workloads I do not own?

No. Authorization first. BinBench will not publish crack/bypass recipes.

Does this teach exploit / side-channel / bypass PoCs via time?

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

Does this teach credential theft via timed command output?

No. Redact secrets, tokens, and PII in Evidence before sharing.
