mkdir tips — authorized directory-create tip checklist

Snapshot

Tip checklist (authorized only)

1. Confirm you may create directories on the lab tree (syllabus box you own).
2. Prefer documenting who / why / ticket before creating production trees — never provision foreign hosts without change control.
3. Record short factual notes; quote short Evidence (flag + mode label + path label — never secrets).
4. Optional: rmdir peer → rmdir-tips when the syllabus prefers empty-dir removal drills.
5. Optional: install peer → install-tips when the syllabus zooms on mode-aware install copies.
6. Prefer disposable lab fixtures for drills; quote non-secret path labels afterward as Evidence.
7. Prefer mkdir / mkdir -p / mkdir -m 0750 read-back — refuse unauthorized foreign-tree cookbooks.
8. Stop at literacy — no attack or unauthorized secret-exfil cookbooks.

Allowed framing

• Classroom labs reviewing mkdir vs install -d vs touch on disposable samples.
• Binding short factual notes as Evidence (flags + mode labels — no secrets).
• Documenting expected vs observed directory modes for authorized notes.
• Comparing mkdir ↔ rmdir / touch / dirname / install 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 mkdir.
• No intentional unauthorized provisioning against foreign trees.
• No secret-theft or credential staging via directory trees.
• No cookbooks that use mkdir as an attack step against production without authorization.
• No mkdir framed as a covert host-staging guide against systems you do not own.

Beginner path (authorized only)

1. Obtain one syllabus-approved disposable lab fixture with coreutils mkdir available.
2. Prefer a throwaway lab path (rmdir-tips, touch-tips) before touching real production trees.
3. With authorization, sample selected create wraps; quote flag + mode label + path label as Evidence.
4. Optional: peer tip pages above when the syllabus asks.
5. Stop at literacy — no attack or unauthorized secret-exfil cookbooks.

Practical notes for authorized labs

• Directory-create tip checklist is the zoom here — keep Evidence labels distinct from rmdir-tips (create ≠ remove) and touch-tips (dir ≠ file stamp).
• Pair with dirname-tips when the syllabus zooms on path-component extraction vs creation.
• Prefer documenting that mkdir -p creates parents and mkdir -m sets mode at create time when comparing syllabus notes.
• Prefer documenting flags, mode labels, and path labels the syllabus authorized.
• Never commit trees of secrets or proprietary host inventories to git — even for labs.

FAQ-aligned refusals (quick)

• Foreign-tree provisioning → refuse.
• Unauthorized secret-exfil / attack cookbooks → refuse.
• Attack/credential-theft framing → refuse.
