Quick answer

df helps authorized labs report filesystem capacity on hosts they own. Pair with top-process-tips, lsof-open-tips, and time-profile-tips.

Tip checklist (authorized only)

  1. Confirm you may inspect mounts on the host (lab VM / your server / courseware).
  2. Prefer human-readable output (-h) and, when useful, inode view (-i) for Evidence.
  3. Record filesystem, size, used%, and mount point notes.
  4. Quote a few lines — avoid dumping every bind mount when not needed.
  5. If a fill is process-related, cross-check with top-process-tips / lsof-open-tips.
  6. Optional: bound long cleanups with timeout-cmd-tips (cleanup itself is out of scope here).
  7. Optional: note that df reports capacity, not "who deleted my file."
  8. Redact mount paths that reveal secrets, home dirs, or PII before sharing.

Allowed framing

  • Classroom labs checking free space before a build.
  • Binding filesystem + used% as Evidence.
  • Documenting "100% full / no space left" as a valid lab outcome.
  • Comparing capacity Evidence with process/open-file peers under one binder.

Scope we will not cover

  • No crack/pirate/keygen via df.
  • No persistence / unauthorized-access / bypass PoCs via df.
  • No credential-theft via mount-path dumps.
  • No destructive wipe/format recipes.

Beginner path (authorized only)

  1. Obtain one syllabus-approved lab VM you control.
  2. Run df -h; quote a few filesystems.
  3. Bind filesystem + used% as Evidence; redact sensitive mounts.
  4. Optional: if a lab disk is full, inspect open files via lsof-open-tips.
  5. Stop at literacy — no unauthorized-access cookbooks.
Which to pick
  • Prefer authorized, human-readable, redacted Evidence.
  • Use top / lsof peers when capacity issues look process-related.
  • No exploit, crack, or unauthorized-access framing.

FAQ

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

A checklist for inspecting authorized filesystem usage on hosts you own — not a cookbook for probing storage you do not control.

How does this relate to top-process-tips and lsof-open-tips?

Those pages cover process load and open files. This page zooms on filesystem capacity Evidence — it does not overwrite those pages.

Can I df sensitive mounts on production hosts I do not own?

No. Authorization first. BinBench will not publish crack/bypass or unauthorized-access recipes.

Does this teach exploit / disk-wipe / bypass PoCs via df?

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

Does this teach credential theft via mount-path dumps?

No. Redact mount paths that reveal secrets or PII before sharing.
