stat tips — authorized metadata tip checklist

Snapshot

Tip checklist (authorized only)

1. Confirm you may read metadata on the lab tree (syllabus box you own).
2. Prefer documenting who / why / ticket before any stat walk — never probe production trees without change control.
3. Record short factual notes; quote short Evidence (mode + size + mtime — never secrets).
4. Optional: file-metadata peer → stat-file-tips when the syllabus zooms on file framing vs general tips.
5. Optional: mode peer → chmod-tips when the syllabus zooms on changing modes vs reading them.
6. Prefer disposable lab fixtures for drills; quote non-secret labels afterward as Evidence.
7. Prefer stat -c '%n %a %s %Y %i' <lab-path> / stat --printf read-back — refuse unauthorized foreign-tree cookbooks.
8. Stop at literacy — no attack or unauthorized privilege-escalation cookbooks.

Allowed framing

• Classroom labs reviewing metadata fields on disposable trees.
• Binding short factual notes as Evidence (mode + size — no secrets).
• Documenting expected vs observed mode/size/mtime for authorized notes.
• Comparing stat ↔ stat-file / chmod / file-magic / sha256sum / file-mime 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 stat.
• No intentional unauthorized metadata walks against foreign trees.
• No secret-theft or credential harvesting from path labels.
• No cookbooks that use stat as an attack step against production without authorization.
• No stat framed as a privilege-escalation guide against systems you do not own.

Beginner path (authorized only)

1. Obtain one syllabus-approved disposable lab fixture with coreutils stat available.
2. Prefer a throwaway lab path (file-magic-tips, chmod-tips) before touching real production trees.
3. With authorization, sample selected format strings; quote mode/size/mtime as Evidence.
4. Optional: peer tip pages above when the syllabus asks.
5. Stop at literacy — no attack or unauthorized privilege-escalation cookbooks.

Practical notes for authorized labs

• General metadata tip checklist is the zoom here — keep Evidence labels distinct from stat-file-tips (tips ≠ file zoom) and chmod-tips (read ≠ change).
• Pair with sha256sum-verify-tips when the syllabus zooms on content hash vs metadata.
• stat -c '%a %s %Y' is a great read-back drill — document selected fields without dumping unrelated privileged state.
• Prefer documenting modes, sizes, mtimes, and inode labels the syllabus authorized.
• Never commit path dumps with secrets or proprietary host inventories to git — even for labs.

FAQ-aligned refusals (quick)

• Foreign-tree metadata walks → refuse.
• Unauthorized privilege-escalation / attack cookbooks → refuse.
• Attack/credential-theft framing → refuse.
