du human tips — authorized -h / human-readable tip checklist
du -h helps authorized labs sample human-readable disk-usage literacy on trees they own. Pair with du-tips, du-disk-usage-tips, du-summarize-tips, df-human-tips, ncdu-scan-tips. Prefer lab VMs — never probe foreign trees without permission. Distinct from du-tips (-h zoom ≠ general du) and du-summarize-tips (human units ≠ summarize-only).

Tip checklist (authorized only)
- Confirm you may read disk usage on the lab tree (syllabus box you own).
- Prefer documenting who / why / ticket before any deep
duwalk — never probe production trees without change control. - Record short factual notes; quote short Evidence (path + human size — never secrets).
- Optional: summarize peer → du-summarize-tips when the syllabus zooms on
-svs-h. - Optional: filesystem peer → df-human-tips when the syllabus zooms on free space vs tree usage.
- Prefer disposable lab fixtures for drills; quote non-secret labels afterward as Evidence.
- Prefer
du -h <lab-path>/du -sh *read-back — refuse unauthorized foreign-tree cookbooks. - Stop at literacy — no attack or unauthorized privilege-escalation cookbooks.
Allowed framing
- Classroom labs reviewing human-readable sizes on disposable trees.
- Binding short factual notes as Evidence (path + human size — no secrets).
- Documenting expected vs observed sizes for authorized notes.
- Comparing du-human ↔ du / du-summarize / df-human / ncdu peer tip pages under one binder.
- Testing syllabus-approved lab fixtures only when change control authorizes that drill on lab resources.
Scope we will not cover
- No crack/pirate/keygen via du.
- No intentional unauthorized disk walks against foreign trees.
- No secret-theft or credential harvesting from path labels.
- No cookbooks that use du as an attack step against production without authorization.
- No du framed as a privilege-escalation guide against systems you do not own.
Beginner path (authorized only)
- Obtain one syllabus-approved disposable lab fixture with coreutils du available.
- Prefer a throwaway lab path (du-tips, ncdu-scan-tips) before touching real production trees.
- With authorization, sample selected
-h/-shoutputs; quote path + human size as Evidence. - Optional: peer tip pages above when the syllabus asks.
- Stop at literacy — no attack or unauthorized privilege-escalation cookbooks.
Practical notes for authorized labs
- Human-readable tip checklist is the zoom here — keep Evidence labels distinct from du-tips (-h ≠ general) and du-summarize-tips (units ≠ summarize-only).
- Pair with df-human-tips when the syllabus zooms on filesystem free space vs tree usage.
du -sh * | sort -his a great read-back drill — document selected sizes without dumping unrelated privileged state.- Prefer documenting path labels, human sizes, and depth flags the syllabus authorized.
- Never commit path dumps with secrets or proprietary host inventories to git — even for labs.
FAQ-aligned refusals (quick)
- Foreign-tree disk walks → refuse.
- Unauthorized privilege-escalation / attack cookbooks → refuse.
- Attack/credential-theft framing → refuse.
- Prefer authorized, redacted, secret-free Evidence.
- Use du / du-summarize / df-human / ncdu peer tip pages when the syllabus asks.
- No crack or unauthorized-access framing.

FAQ
What is a "du human tip" page in BinBench framing?
A checklist for authorized human-readable Evidence (du -h / -sh / block units on lab trees) on hosts you own or were given syllabus access to — not a cookbook for probing foreign trees without permission.
How does this relate to du-tips / du-disk-usage-tips / du-summarize-tips / df-human-tips / ncdu-scan-tips?
du-tips covers general du; du-disk-usage-tips covers usage framing; du-summarize-tips covers -s summarize; df-human-tips covers filesystem free space; ncdu-scan-tips covers interactive ncdu. This page zooms on a human-readable (-h) tip checklist — it does not overwrite those pages.
Can I du trees I do not own?
No. Authorization first. BinBench will not publish unauthorized disk-usage probes against foreign hosts or unlicensed trees.
Does this teach attack or privilege-escalation PoCs via du -h?
No. Mentions of attack/bypass appear only as refusals. Authorized literacy only — prefer lab VMs and redacted path labels. Never teach hostile disk walks as an attack step.
Does this teach secret theft via du -h?
No. Never paste du dumps with secrets, foreign host inventories, or credential-bearing paths into notes. Prefer documenting path labels, human sizes, and depth flags only.
