Quick answer

df helps authorized labs sample filesystem-usage literacy on hosts they own. Pair with df-disk-tips, df-human-tips, du-disk-usage-tips. Prefer lab VMs you administer — never treat foreign hosts as capacity-recon targets.

Tip checklist (authorized only)

  1. Confirm you may read filesystem usage on the host (lab VM you own).
  2. Prefer df -h on syllabus labs.
  3. Record Filesystem/Size/Used/Avail/Mounted; quote short Evidence.
  4. Optional: disk-focused → df-disk-tips; human → df-human-tips.
  5. Optional: directory sizes → du-disk-usage-tips; block → lsblk-tips.
  6. Optional: memory → free-tips.
  7. Redact mount paths and org volume labels if policy requires.
  8. Stop at literacy — no fill-disk / DoS cookbooks.

Allowed framing

  • Classroom labs reading filesystem usage on a lab VM.
  • Binding df notes as Evidence.
  • Documenting Avail vs Used columns for authorized capacity notes.
  • Comparing df ↔ du / lsblk under one binder.

Scope we will not cover

  • No crack/pirate/keygen via df.
  • No exploit / fill-disk / DoS / bypass PoCs.
  • No credential-theft via filesystem recon.
  • No intentional df against hosts you do not own.

Beginner path (authorized only)

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

FAQ

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

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

How does this relate to df-disk-tips?

df-disk-tips covers disk-oriented df Evidence. This page zooms on a general df tip checklist — it does not overwrite that page.

Can I use df 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 df?

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

Does this teach credential theft via filesystem recon?

No. Redact mount paths and org volume labels before sharing excerpts.
