Git history scrub — sensitive personal terms

Plaintext references to personal legal matters in committed worklogs (WRKLOG-2026-03-14, WRKLOG-2026-04-18). Forward-fixed but old commits still contain strings. Requires git filter-repo + force-push. See runbook below.

SECURITY — sensitive terms in public git history

Runbook: Git History Scrub (d000 Personal Terms)

Problem: Two committed worklogs contained plaintext references to personal legal matters. The files have been edited (forward-fix), but git history retains the original text in prior commits.

Affected commits: Any commit touching these files:

# Identify affected commits
git log --oneline -- \
  docs/modules/ROOT/pages/2026/03/WRKLOG-2026-03-14.adoc \
  docs/modules/ROOT/pages/2026/04/WRKLOG-2026-04-18.adoc

Scrub procedure:

# 1. BEFORE: Full backup of the repo
cp -a ~/atelier/_bibliotheca/domus-captures ~/atelier/_bibliotheca/domus-captures.bak

# 2. Install git-filter-repo (if not present)
# Arch: pacman -S git-filter-repo
# pip: pip install git-filter-repo

# 3. Create expressions file for replacement
cat > /tmp/scrub-expressions.txt << 'EXPR'
regex:(?i)divorce==[REDACTED]
regex:(?i)dissolutio(?!n\.adoc\.age)==[REDACTED-LEGAL]
regex:(?i)iliana==[REDACTED-NAME]
regex:(?i)angulo-arreola==[REDACTED-NAME]
regex:legal-divorce-notes\.age==legal-notes.age
regex:1099-NEC-iliana==1099-NEC
EXPR

# 4. Verify before (dry run — count matches in history)
git log -p --all -S 'divorce' -- '*.adoc' | grep -c 'divorce' || echo "0 matches"
git log -p --all -S 'iliana' -- '*.adoc' | grep -c 'iliana' || echo "0 matches"

# 5. Run filter-repo (DESTRUCTIVE — rewrites all commit hashes)
git filter-repo --replace-text /tmp/scrub-expressions.txt --force

# 6. Verify after
git log -p --all -S 'divorce' -- '*.adoc' | grep -c 'divorce' || echo "0 matches — CLEAN"
git log -p --all -S 'iliana' -- '*.adoc' | grep -c 'iliana' || echo "0 matches — CLEAN"

# 7. Re-add remotes (filter-repo removes them)
git remote add origin git@github.com:<user>/domus-captures.git
# Add any other remotes (Gitea, etc.)

# 8. Force-push to all remotes (DESTRUCTIVE — overwrites remote history)
git remote | xargs -I{} git push {} main --force

# 9. Clean up
rm /tmp/scrub-expressions.txt
rm -rf ~/atelier/_bibliotheca/domus-captures.bak  # only after verifying

Post-scrub checklist:

  • Backup created before running

  • git filter-repo installed

  • Expressions file reviewed — no false positives (e.g., Don Quijote "Angulo el Malo" is in segunda-parte/texto/texto-011.adoc — the regex targets angulo-arreola specifically to avoid this)

  • Dry-run counts match expectations

  • Filter-repo executed

  • Post-scrub verification shows 0 matches

  • Remotes re-added

  • Force-pushed to all remotes

  • Cloudflare Pages rebuild verified

  • Local clones on other machines re-cloned or git fetch --all && git reset --hard origin/main

  • Backup removed

Domus Digitalis — Session Handoff

Domus Digitalis — Session Handoff (2026-07-05 → 06)

Handoff for a fresh agent picking up domus-digitalis. Covers the two repos, the conventions to follow, what was accomplished, repo/commit state, the shared-checkout gotcha, and open items.

What this is

domus-digitalis is a full-stack project & library manager (Next.js 15 + Express + Prisma + PostgreSQL 16 + Redis 7), run Docker-only in dev. Two locations:

  • Code repo: ~/atelier/_projects/personal/domus-digitalis (the app; git remote EvanusModestus/domus-digitalis, private).

  • Book (docs): ~/atelier/_bibliotheca/domus-captures/data/d000/projects/domus-digitalis/standalone AsciiDoc (build with build-adoc / asciidoctor -a env-d000, not Antora).

Conventions to follow
  • All docs live in the book, not the code repo. Update partials there; verify with a clean asciidoctor -a env-d000 build.

  • All scripts / patches / one-offs live in <book>/scripts/ (STD-027): executable, set -euo pipefail, commented for learning, referenced via bash $(find … -name '…').

  • DB scripts connect via $DATABASE_URL, not docker compose exec. Load creds first: ds d000 dev/domus-digitalis; guard with : "${DATABASE_URL:?…}".

  • Two dsec envs: d000/dev/app = full app env (~76 vars, decrypted by setup-domus-dev.sh for the containers); d000/dev/domus-digitalis = host DB tooling (DATABASE_URL @localhost + DB_*).

  • Env rule: URL-safe (hex) DB password; keep only discrete DB_* in envs and let Compose assemble DATABASE_URL — never a literal DATABASE_URL: line (breaks .env parsing).

What was accomplished
  • Docker-only dev stack; setup-domus-dev.sh brings up the full Compose stack.

  • Fixed Redis wiring (REDIS_URL: redis://redis:6379).

  • Reconciled backend/frontend schema.prisma (byte-identical, @updatedAt, binaryTargets incl. linux-musl).

  • Built a dependency-free API contract checker (scripts/check-api-contract.js, wired to npm test); removed 4 dead frontend handlers + a dead src/middleware.ts (hardcoded Basic-Auth cred — private repo, low risk).

  • Fixed seed atomicity; documented raw-SQL-through-Prisma seeding.

  • Added POST /api/projects; DB has 84 real projects (test rows cleaned; id 108 = "Platform Hardening", 109 = "domus-index").

  • Isolated dsec env (create-secret.sh) + resolved an AppArmor block on /usr/bin/age reading /dev/shm (added owner /dev/shm/dsec* rwk,).

  • Book fully updated: dual-surface API (23 backend endpoints), CLI cookbook, portfolio, dev workflow, all 11 scripts cataloged, package-lock churn note.

  • Improved STD-027 (Starter Template + Migration recipe).

Repo state
Repo main / notes

Code (domus-digitalis)

main = merge 785f35c. Unpushed.

Book (domus-captures)

main advancing (6d5952b…). Unpushed. Working tree clean.

apps/frontend/package-lock.json churns cosmetically on every up — set git update-index --skip-worktree on it.

Critical gotcha — shared checkout

domus-captures is a shared working directory — another agent works on domus-index in the same checkout. git add -A / git commit races swept our staged files into domus-index commits twice this session. Stage explicit paths only; coordinate before committing.

Open items
  • Push both repos (book push → docs.domusdigitalis.dev auto-deploys via Cloudflare).

  • Delete merged branches (fix/docker-schema-middleware; docs/domus-digitalis-*).

  • Optional: health endpoint doesn’t probe Postgres (add a DB ping); backend is plain JS (no tests beyond the contract check).

Domus Index — Session Handoff

Context

domus-index is a C-based AsciiDoc corpus indexer built in a single session (2026-07-05/06). It scans domus-captures (11,324 .adoc files, 7.8M words), extracts structural metadata, stores full content in Postgres via libpq, and enables full-text search in Spanish + English.

Repo: ~/atelier/_bibliotheca/domus-captures (branch: main)

Project path: data/d000/projects/domus-index/

Standalone AsciiDoc book (not Antora) — built with build-adoc, not make.

27 commits from scaffold to animated D2 diagrams. All on main — atomic commits, no feature branches.

Current State

Completed (Phases 0–10 of 13)
  • Phase 0: Postgres 16 in Docker (domus-index-postgres:5433), dsec credentials (ds d000 dev/domus-index), gcc 16 + libpq 18 + OpenSSL 3.6.3

  • Phase 1: scanner.c — recursive opendir/readdir, 11,324 files, --exclude support

  • Phase 2: parser.c — title, headings (62,475), word count (7.8M), line count

  • Phase 3: hasher.c — SHA-256 via OpenSSL EVP, change detection (skip unchanged)

  • Phase 4: database.clibpq parameterized upsert with RETURNING id, heading upsert (delete+insert)

  • Phase 5: main.c — full pipeline, 11,324 docs, 0 errors

  • Phase 6: SQL exploration — corpus stats, directory distribution, heading search, project slug queries

  • Phase 7: Content storage + FTS — content TEXT, dual-language tsvector (Spanish primary, English fallback), GIN index, ISS-005 tsvector truncation fix (left(content, 400000))

  • Phase 8: report.c — generates partials/reports/corpus-summary.adoc from SQL, Antora page shell at pages/reports/corpus-index.adoc

  • Phase 9: CLI arguments — --report, --exclude <path>, --query "<sql>", --help

  • Phase 10: Project slug extraction — extract_slug() infers project from path prefixes, 20+ projects identified

  • pipeline.d2 — D2 animated (marching ants + 5 frame transitions)

  • project-structure.d2 — directory layout

  • system-overview.d2 — 5-layer animated architecture (marching ants + frame transitions)

Conventions

Critical Rules
  • Document before implement. Update plan.adoc BEFORE writing code. Never implement then backfill.

  • STD-027: Script Extraction. Bash blocks >5 lines go in scripts/. Partials show only the run command — no include:: of source, no [%collapsible] for scripts. SQL schemas use [%collapsible] with include::.

  • No hardcoded credentials. All database access via $DATABASE_URL from dsec. Binary refuses to start without it.

  • Callouts over tables. SQL examples use <1>, <2> callout syntax with WHY explanations, not summary tables.

  • No ASCII art. D2 + Graphviz only. Definition lists for conceptual content, literal blocks (…​.) for flow diagrams.

  • Marching ants. style.animated: true on D2 data flow connections. style.stroke-dash: 3 for static infrastructure.

  • Verb pattern. Build scripts use build/open/help verbs. bash scripts/build-domus-index.sh open html obsidian-amber.

  • C source comments. Every function has WHY comments — not just WHAT. Cross-reference ISS-NNN from appendix-issues.adoc.

Known Issues
ID Issue

ISS-001

path[4096] buffer may truncate deeply nested paths

ISS-002

Decrypted d001/d002 files indexed if running during d001 open — mitigate with --exclude

ISS-003

MAX_HEADINGS (256) cap silently drops headings — Aristotle and Cicero texts hit this

ISS-005

tsvector 1MB limit — resolved with left(content, 400000) truncation in trigger

Future Considerations (Not Yet Planned)
  • Association engine importscripts/import-associations.sh exists but hasn’t been run yet. 602+ YAML triples → document_relationships table.

  • STD for database-corpus sync — user wants a standard governing how domus-index stays in sync with domus-captures.

  • C learning annotations — source files have WHY comments now, but a dedicated learning guide (phase-by-phase walkthrough) was discussed and deferred.

  • Hosting — user asked about hosting the database externally. Architecture supports it (DATABASE_URL is location-agnostic). Deferred.

  • MAX_HEADINGS increase — 256 cap hits on classical texts. Either increase to 1024 or switch to dynamic allocation.

ISE API Toolkit

ISE API Toolkit — Session Proven

Built and tested a complete ISE API export pipeline covering all 5 API surfaces (ERS, MnT, OpenAPI, DataConnect, pxGrid). Tier-agnostic — same scripts, ds d000 or ds d001.

Scripts Built
Script Purpose

validate-endpoint-data.sh

Per-surface diagnostic — checks 7 API surfaces with WHY for empties. Handles single object + array JSON.

test-endpoint-workflow.sh

End-to-end: profile → validate → CSV → coverage report. Output to /tmp/ise-test-<slug>-<timestamp>/.

ise-full-export.sh

Complete ISE snapshot — 27 exports across ERS, MnT, OpenAPI, DataConnect, pxGrid. Parallel where safe. Chains policy-set IDs for authn/authz rules.

ise-export-to-csv.sh

JSON → CSV converter — flattens ERS SearchResult, OpenAPI response, MnT, DataConnect structures. 25 CSVs.

endpoint-csv-export.sh (fixed)

Multi-endpoint array support — was object-only, now iterates each endpoint in array.

Bugs Fixed
  • endpoint-csv-export.sh and validate-endpoint-data.sh both failed on multi-endpoint JSON (array vs object). Fixed with jq 'type' detection and per-element iteration.

  • ise-full-export.sh OpenAPI authn/authz rules required <policy-set-id> argument. Fixed by chaining: fetch policy sets first, extract IDs, query rules per set in parallel.

Patterns Rewritten
  • endpoint-onboard.adoc (daily capture + pattern) — raw curl in Steps 3-4 replaced with ise-endpoint-create.sh + ise-endpoint-get.sh. Dry-run support, pre-flight validation.

  • validate-data.adoc — 42 lines of inline jq replaced with validate-endpoint-data.sh reference.

  • profile-csv-workflow.adoc — added validation step and test-endpoint-workflow.sh reference.

  • New pattern: full-export-workflow.adoc — 4-step ISE snapshot pipeline.

2026-07-06 22:00:48  MAB / Lookup  →  Fail  →  "15039 Rejected per authorization profile"
Policy: Domus_MAB → Default → DenyAccess

This looked like dot1x never fired. Wrong. On a multi-auth port, the switch sends both dot1x and MAB simultaneously. MAB gets a fast Deny from ISE (correct behavior), then dot1x completes with EAP-TLS Pass. The DataConnect auth log captured the MAB Fail first because it completed faster.

Never diagnose session state from DataConnect timing alone. The switch show access-sess is the authoritative source. DataConnect is a historical log with write latency.

Wireless — PMK Cached

The wireless interface (E0:D5:5D:6C:E1:66) showed an active MnT session but:

  • MnT auth history: 0 records — last real EAP-TLS auth was 2026-07-01 (5 days ago)

  • Wire attributes: WLC metadata only — no CertificateIssuer, TLSVersion, CipherSuite

  • DataConnect endpoint: null — profiler hasn’t populated the DC endpoint table

All caused by PMK cache — the WLC is holding the session without re-auth. To get full cert/TLS data: clear wireless client pmk-cache mac-address E0:D5:5D:6C:E1:66 on WLC, then re-profile.

Scripts Built (5 .ps1, encrypted)
Script Purpose

dcr-env.ps1

Shared environment — subscription, tenant, workspace, DCE IDs. Dot-source before anything.

new-custom-tables.ps1

Create ISEAuth_CL, ASAPerimeter_CL, ColdDatalake_CL with full schemas. -DryRun preview.

new-dcr.ps1

Create 3 DCRs with KQL transforms. -Target ise|asa|datalake|all. ISE KQL classifies 27 categories into hot/cold/discard.

validate-pipeline.ps1

End-to-end pass/fail/skip: context, DCEs, DCRs, custom tables, data flow.

export-csv-reports.ps1

9 CSV reports: DCR inventory, DCE inventory, ARM resources, associations, tables, custom tables, ingestion volume, source facilities, pipeline status.

Field Notes

Two AsciiDoc captures in scripts/ document the raw Azure session:

  • v1 — Troubleshooting doc. Diagnosed null $ws variable. Root cause: workspace object uninitialized, not an auth issue. Fast recovery procedure documented.

  • v2 — Full operations runbook. DCE/DCR CRUD, full JSON export of all 5 DCRs with data flows, VM discovery, DCR association enumeration. 800+ lines of real Azure output.

Attributes Filled
  • {resource-group}infosec-rg-usw3-001

  • {dce-endpoint} → Monad-DCE ingest URL

  • {subscription-id}, {tenant-id}, {workspace-id} — all populated from discovery

  • {azure-region} corrected: westus3 (was westus2)

  • 7 existing DCR/DCE attributes added for reference

Key Correction

DataConnect auth log timing vs switch session state. On multi-auth ports (1X_MAB), the switch tries dot1x and MAB simultaneously. MAB gets a fast DenyAccess, then dot1x completes with Pass. DataConnect may show the MAB Fail as the latest entry before the dot1x success is written. The switch is authoritative for session state — always verify with show access-sess int <port> d.

P0 Fixes — Resolved This Session
  • Rewrite ISE API patternsendpoint-onboard.adoc (daily capture + pattern) now uses ise-endpoint-create.sh and ise-endpoint-get.sh instead of raw curl. All lifecycle scripts: create, get, move.

  • Extract inline validation code to scriptvalidate-endpoint-data.sh replaces 42 lines of inline jq in validate-data.adoc. Diagnoses all 7 API surfaces with WHY for empties.

  • End-to-end test scripttest-endpoint-workflow.sh runs profile → validate → CSV → coverage report in one command. Output captured to /tmp/ise-test-<slug>-<timestamp>/.

  • Pattern files updatedpatterns/ise/endpoint-onboard.adoc and patterns/ise/validate-data.adoc now reference canonical scripts, not inline code.

  • Apply [TIP.terminal] + [%collapsible] wrapper to remaining code blocks

  • Add [%collapsible] to STD-001 audit tables — large inventory tables should collapse by default

  • Audit remaining daily capture partials for inline code that should be scripts or pattern includes

Pending — Next Session
  • CiscoLive BRKSEC-2347 + BRKSEC-1038 AsciiDoc extraction (raw materials saved in data/d000/education/ciscolive-ise-deployment/)

  • SIEM DCR pipeline PowerShell commands — 13 partials scaffolded, none executed

  • Full ideation-intake restructure (active ideas, graveyard, appendices need same granularity)

  • daily-capture.sh update to scaffold new directory structure

  • William Cox Lenovo Ubuntu imaging + EAP-TLS validation — due Monday 2026-07-13

  • Guest ACL update — guest redirect ACL work needed. Lab validate GUEST_CWA_REDIRECT_MAX_SECURITY in d000, then joint CR with NE. On today’s task list.

  • Disaster Recovery & Downtime Procedures — ISE top priority (dot1x closed mode = SPOF for network access)

    • ISE DR: Document failover sequence — PAN, MnT, PSN priority order

    • ISE DR: RADIUS dead-server detection on WLCs/switches — critical-auth VLAN fallback

    • ISE DR: Backup/restore procedures — scheduled config backups, tested restores

    • FTD/FMC DR: FMC loss = no policy management

    • Network DR: Core/distribution switch failure, STP reconvergence, HSRP failover

    • Document RTO/RPO per system

SIEM Migration (QRadar → Sentinel)

  • SIEM QRadar → Sentinel Migration — LEAD ROLE. 4 collection iterations (Apr 16, 17, 17-streamlined, 20-streamlined). Python chart pipeline built (qradar-charts.py). Migration XLSX generated. Verification pending. Comms sent Apr 23.

    • d001 artifacts: 8 JSON exports, 2 CSV inventories, migration XLSX, top5 source SVG/PNG, verification doc

    • Dependency: Monad pipeline for log source transition

    • Dependency: Sentinel KQL proficiency for query migration

  • Monad Pipeline Evaluation (origin: 2026-03-11) — lead role. Console error RESOLVED 05-12. 06-09: Architecture decision — rsyslog (CHLXSYSLOG01) as collection tier → Monad → Sentinel. ISE lab → rsyslog → Monad 6-step execution guide created with 10 API calls. ASA lab logs already flowing through rsyslog. DCR still needed — Victor + Mauricio.

  • Sentinel KQL — build proficiency, distinguish from team. Azure portal access acquired.

  • QRadar log source report — run AQL queries, fetch JSON, generate Python Excel

Active Deployments & Migrations

  • MSCHAPv2 Migration — 6-sheet Standard Report ready. Migration window 05-04 to 05-30 CLOSED. Confirm final report status and next steps with team. 6,227 MSCHAPv2 devices, 14,249 EAP-TLS/TEAP (70% migrated).

  • MSCHAPv2 weekly cadence — recurring Wednesday call established (first 04-22). Completed 2026-04-22.

  • MSCHAPv2 ownership matrix — sent in scoping email 4/24 with manager callouts (@Albert, @John). Completed 2026-04-24.

  • TCP Clocks deployment — Batch 1: 7 clocks validated (OUI 40:AC:8D). Batch 2 (06-09): 9 new MACs (OUI 40:AC:BD) added via ERS. 1 one-off reassigned. New switch deployed without RADIUS/AAA — clocks can’t authenticate. Switch onboarding template + 3 validation queries documented. ERS queries self-contained with ers function.

  • SRT Research VLAN — confirm roles with Tony Sun: Tony implementor, Evan tester. CAB approved 04-21.

  • Downtime Computers enforcement — draft ISE AuthZ rule: medigate_724 + Wireless = DenyAccess. Separate CR. d001: DC queries, audit CSVs (v1-v3), wireless violations report delivered 04-21.

  • Enterprise Linux 802.1X — standardize Shahab/Ding deployment (CISO priority). Overdue since 02-24. Blocked by nmcli cert fix. 06-15: Assembler build fixed (26 errors → 0). Segmentation document extension to 06-16. d001 open linux-research to work on it.

  • Abnormal Security — CR-2026-05-07. Implemented 05-13. 06-09 update: Full policy review — 20-section EOP validation commands rebuilt, Hoxhunt SCL-1 investigation (intentional bypass confirmed), sclizer junk folder triage (~800 emails), Outlook reactions audit added, Connect-ExchangeOnline msalruntime fix documented. ESA migration expansion in progress — priority to move off ESA to full environment.

    • Team: Cox/William, Landeros/Jason, Rosado/Evan, Naranjo/Mauricio, Sandoval/Carlos

  • ASA VPN: Okta RADIUS → Entra SAML — (NEW 06-09) 5-phase migration plan built. ASA baseline captured (2 tunnel groups: CHLA_CORPORATE_USERS, CHLA_BYOD_USERS). 6 ISE policy screenshots.

  • Tube System Upgrade — iTrack 3528165. 15x 10" TS stations need MAC addresses added to ISE identity group IoT_Onboard. MACs received from vendor (C8:1A:FE:20:xx:xx series). Station list spans ICU (CTICU, PICU, BMT, NICU, NICCU), ED, Surgery, Trauma, Pharmacy. Vendor contact: John Genest. Rationale: manufacturer no longer supports current system; failure risks delayed/missed patient care.

BMS Controller Segmentation (MIGRATED — 06-09)

  • BMS Controller Segmentation — Full migration from Principia LaTeX to d001. 12 partials, 5 Mermaid diagrams, 4 legacy PDFs, ISE screenshots. d001 open bms-controller. Completed 2026-06-09.

Revalidate — confirm no flapping since 04-24.

  • IoT device validation queries — v2 created with partials architecture, 16 queries across ERS/MnT/DataConnect/FMC. Completed 2026-04-24.

Stale Blockers (carried via carryover tracker)

  • k3s NAT verification — rule 170, 10.42.0.0/16 pod network (origin: 2026-03-09). 92 days. Blocks Wazuh indexer recovery → blocks SIEM visibility. Decide: test or defer to Q3.

  3. AI review for grammar, vocabulary, register

  4. Build comprehensive understanding of literary elements

Today’s Study

  • Focus: CISSP (41 days to July 12 exam — schedule exam today 06-01), MSCHAPv2 migration wrap-up

  • Secondary: RHCSA curriculum, Spanish SIELE C1

  • CISSP — Security & Risk Management (continuing). Schedule exam this afternoon.

  • RHCSA — continue curriculum phase

  • Spanish — Don Quijote reading + analysis (DTLA study day)

  • MSCHAPv2 — migration window closed 05-30, review final report

Regex Training (CRITICAL)

  • Status: 52 days carried over (since 2026-03-16)

  • Priority: After PeopleSoft, before Quijote

  • Session: Character classes, word boundaries

Quick Commands

Git & GitHub CLI

create GitHub repo from existing local repo
gh repo create <name> --private --source . --remote origin --push
clone a forked repo into a specific directory
gh repo clone EvanusModestus/PowerShell ~/atelier/_projects/work/PowerShell
gh repo clone defaults to SSH. If key is passphrase-protected, load agent first: eval "$(ssh-agent -s)" && ssh-add ~/.ssh/id_ed25519_github
cross-repo commit search — all domus repos on a specific date
for repo in ~/atelier/_bibliotheca/domus-*/ ~/atelier/_projects/personal/domus-*/; do
  [ -d "$repo/.git" ] || continue
  name=$(basename "$repo")
  git -C "$repo" log --since="2026-04-06" --until="2026-04-07" --format="%h %aI %s" 2>/dev/null |
    awk -v r="$name" '{print r, $0}'
done
commit history touching only today’s modified files
git log --oneline -- $(find . -name "*.adoc" -type f -newermt "$(date +%F)")
unstage a file without losing changes
git restore --staged data/d001/api/ise-dataconnect/output/output-2026-04-24

Safe — removes from staging area only. Working tree is untouched. Use when you accidentally git add a plaintext or output file.

gh CLI — repo discovery and filtering

list repos by name pattern (domus/antora ecosystem)
gh repo list --limit 100 --json name,description \
  | jq -r '.[] | select(.name | test("domus|antora|asciidoc"; "i")) | "\(.name)\t\(.description)"'
top 20 most recently updated repos
gh repo list --limit 100 --json name,description,updatedAt \
  | jq -r 'sort_by(.updatedAt) | reverse | .[:20] | .[] | "\(.updatedAt[:10])\t\(.name)\t\(.description)"'
top 10 repos by disk usage
gh repo list --limit 100 --json name,diskUsage \
  | jq -r '.[] | "\(.diskUsage)\t\(.name)"' | sort -rn | head -10
clone a repo that’s not local yet
gh repo clone EvanusModestus/<repo-name> ~/atelier/_bibliotheca/<repo-name>

find & grep

files modified since midnight today (precise — not "last 24 hours")
find . -name "*.adoc" -type f -newermt "$(date +%F)" | sort
-mtime 0 means "last 24 hours", not "today". -newermt "$(date +%F)" compares against midnight — exact.
case-insensitive file search
find . -iname "*mschap*" -type f | sort
multiple name patterns with -o
find . -type f \( -iname "*ise*" -o -iname "*mschap*" \) | sort
same thing, single regex — fewer parens, extensible
find . -type f -iregex '.*\(ise\|mschap\).*'
exclude directories
find . -type f -iname "*meeting*" \
  -not -path "*/node_modules/*" \
  -not -path "*/.git/*" \
  -not -path "*/build/*"
recent drafts by modification time (newest first)
find .drafts -type f -printf '%T@ %Tc %p\n' | sort -rn | awk '{$1="";print}' | head -3
grep — know what you’re counting
grep -rl "pattern" . --include="*.adoc"         # file count (which files)
grep -rn "pattern" . --include="*.adoc"         # line matches (every occurrence)
grep -rc "pattern" . --include="*.adoc" | grep -v ':0$'  # match count per file
search with context — avoid opening the file
grep -rn -E 'git init|gh repo create' docs/ --include='*.adoc' -B2 -A2

Search codex by content — which files contain a command?

find all PowerShell files that use a specific cmdlet
find docs/modules/ROOT/examples/codex/powershell -type f -name "*.adoc" \
  -exec grep -l 'Get-Process\|Start-Process\|pipeline\|Where-Object' {} \;

Pattern: find -exec grep -l returns only filenames with matches — like grep -rl but with find’s `-type f -name filtering. Use \| for OR in grep basic regex. Swap the pattern for any cmdlet or keyword to locate coverage across the codex.

inventory a codex tool directory — count files per tier
find docs/modules/ROOT -name "powershell" -type d \
  -exec sh -c 'echo "$1: $(find "$1" -type f | wc -l) files"' _ {} \;
find orphaned examples (not included by any page)
for f in $(find docs/modules/ROOT/examples/codex/powershell -name "*.adoc" -type f); do
  base=$(basename "$f")
  dir_parent=$(basename $(dirname "$f"))
  grep -rq "$dir_parent/$base" docs/modules/ROOT/pages/codex/powershell/ \
    docs/modules/ROOT/examples/codex/powershell/*.adoc 2>/dev/null \
    || echo "ORPHAN: $f"
done

find → grep → open in nvim

find by path + content, open result in nvim
nvim $(find -path '*oauth*' -name '*.adoc' -type f \
  -exec grep -l 'timeout\|expire\|reconfig\|token' {} \;)

Command substitution $(…​) feeds all matches as arguments to nvim — opens every hit as a buffer. :bn/:bp to cycle, :ls to list. One file? Opens directly. Five files? All loaded, ready to navigate.

find by content across entire tree, open in nvim
nvim $(find docs/modules/ROOT -name '*.adoc' -type f \
  -exec grep -l 'token.*expire\|oauth.*refresh' {} \;)
open one at a time (sequential — -exec nvim per match)
find -path '*oauth*' -name '*.adoc' -type f \
  -exec grep -l 'timeout\|expire' {} \; \
  -exec nvim {} \;
Trailing \| in grep patterns matches empty string — every file matches. Always end with a term, not a pipe: 'timeout\|expire\|token' not 'timeout\|expire\|token\|'.

Trace Antora partial inclusion chains

who includes this partial? (one level up)
grep -rl 'commands/shell' docs/modules/ROOT/partials/
count all pages that include a partial
grep -rl 'quick-commands' docs/modules/ROOT | wc -l
full chain: partial → assembler → every page that uses it
file="commands/shell"
grep -rl "$file" docs/modules/ROOT/partials/ | while read f; do
  parent=$(basename "$f" .adoc)
  echo "$file -> $parent"
  grep -rl "$parent" docs/modules/ROOT/pages/ | while read p; do
    echo "  -> $(basename "$p")"
  done
done

Pattern: grep -rl finds which files contain the string. Chain two passes — first finds the assembler partial, second finds every page that includes it. Works for any partial in the Antora include hierarchy.

Multi-pattern file search — worklog partial discovery

brute force — one find per partial name
find docs/modules/ROOT -name "*urgent.adoc*" -type f
find docs/modules/ROOT -name "*morning.adoc*" -type f
consolidated — single find with regex (production approach)
find docs/modules/ROOT -type f -regextype posix-extended \
  -regex '.*(urgent|morning|work-chla|personal|education|infrastructure|quick-commands|related)\.adoc' \
  | sort

Pattern: -regextype posix-extended enables | alternation without escaping. One process, one sort — versus 8 separate finds. The sort deduplicates visually and groups by path.

pipeline alternative — find piped to grep
find docs/modules/ROOT -type f -name "*.adoc" \
  | grep -E 'urgent|morning|work-chla|personal|education|infrastructure|quick-commands|related'

Trade-off: the pipeline version is more readable but spawns two processes. The regex version is a single find — faster on large trees, same result.

Cross-repo literary term search — bibliotheca-wide discovery

When searching for a term across the entire _bibliotheca (multiple repos, mixed file types), these patterns escalate from narrow to broad.

1. Single repo — count matches per file
grep -rn --include='*.adoc' -c 'sanchuelo' . | grep -v ':0$'
2. Cross-repo — filenames only (all bibliotheca)
grep -rl --include='*.adoc' -i 'sanchuelo' ~/atelier/_bibliotheca/ | sort
3. Cross-repo with context — see the line in situ
grep -rn --include='*.adoc' -i -B1 -A1 'sanchuelo' ~/atelier/_bibliotheca/domus-captures/
4. Multi-filetype — .adoc + .txt (catches source texts)
grep -rl -i 'sanchuelo' ~/atelier/_bibliotheca/ --include='*.txt' --include='*.adoc' | sort
5. Null-safe find + xargs — handles spaces in paths
find ~/atelier/_bibliotheca/ -type f \( -name '*.adoc' -o -name '*.txt' \) -print0 \
  | xargs -0 grep -li 'sanchuelo' | sort
6. Open all hits directly in nvim
grep -rl -i 'sanchuelo' ~/atelier/_bibliotheca/ --include='*.adoc' --include='*.txt' | xargs nvim

Pattern escalation: #1 confirms the term exists and where. #2 expands to all repos. #3 shows context without opening files. #4 adds plain text sources (Quijote .txt originals). #5 is the safe version for automation. #6 opens everything for editing.

Trade-off: grep -r --include is faster for known file types. find | xargs grep is safer for paths with spaces and more extensible (add -name '*.md' etc.). For literary searches across the bibliotheca, #4 or #5 is usually the right starting point — the source texts are .txt, not .adoc.

Search daily notes — find commands, builds, and patterns across worklogs

Source: 2026-06-22 — searching for build-antora-page invocations and theme usage across partials

which daily note partials mention a command?
# Find files — filenames only
grep -rl 'build-antora-page' docs/modules/ROOT/partials/worklog/
see the match in context without opening the file
# 3 lines of context around each hit
grep -rn -C3 'build-antora-page' docs/modules/ROOT/partials/worklog/
search for any theme flag across all partials (PCRE alternation)
grep -rPn 'theme\s+(light-cyan|catppuccin|mocha)' docs/modules/ROOT/partials/
find + grep — search all daily note partials for build/export patterns
find docs/modules/ROOT/partials/worklog/daily-notes -name '*.adoc' \
  -exec grep -l 'build-antora-page\|build-adoc\|--theme\|pdf' {} \;
find + awk — show filename:matching_line for every hit (no -r needed)
find docs/modules/ROOT/partials/worklog/daily-notes -name '*.adoc' \
  -exec awk '/build-antora-page|build-adoc|--theme/{print FILENAME": "$0}' {} \;
awk state machine — extract full [source,bash] blocks containing a command
find docs/modules/ROOT/partials -name '*.adoc' -exec \
  awk '/^\[source,bash\]/{block=1; buf=""} \
       block{buf=buf"\n"$0} \
       /^----$/ && block>1{if(buf~/build-antora-page/) print FILENAME":"buf; block=0} \
       block{block++}' {} \;

The awk state machine: [source,bash] sets block=1 and starts buffering. Each line appends to buf. When the closing ---- arrives (and block>1 to skip the opening fence), check if the buffer contains the target command. If yes, print filename + entire block. Reset. One pass, arbitrary block size, no temp files.

sed address range — print only lines between code fences matching a pattern
find docs/modules/ROOT/partials/worklog -name '*.adoc' -exec \
  sed -n '/\[source,bash\]/,/^----$/{/build-antora-page/p}' {} +
search data/ too — standalone adoc outside Antora
grep -rn 'build-antora-page\|build-adoc' data/ --include='*.adoc'
every invocation sorted by path (chronological by date directory)
grep -rn 'build-antora-page' docs/modules/ROOT/partials/worklog/daily-notes/ \
  | awk -F: '{print $1, $3}' | sort

Pattern escalation: grep -rl → "where is it". grep -rn -C3 → "what’s around it". find -exec awk → "extract the structured block". sed address ranges → "print between delimiters". Each tool has a different affordance — grep finds, awk extracts structure, sed filters ranges, find -exec scales across trees.

Email thread analysis — extract people, dates, commitments, silence

who’s in the thread (@ mentions + From headers)
grep -P '(@\w+|^From:.*<)' comms.adoc
timeline — every date with context
grep -nP '\d{1,2}/\d{1,2}/\d{2,4}|20\d{2}-\d{2}-\d{2}' comms.adoc
commitments — who promised what
grep -niP '(I can |I will |I.ll |we will |we.ll )' comms.adoc
open questions and unknowns
grep -niP '(\?|need to confirm|need to validate|TBD|pending)' comms.adoc

comm — set difference (who hasn’t replied)

# All recipients
grep -oP '<\K[^>]+' comms.adoc | sort -u > /tmp/all-recipients

# All senders
grep -P '^From:' comms.adoc | grep -oP '<\K[^>]+' | sort -u > /tmp/replied

# Who's silent — follow-up targets
comm -23 /tmp/all-recipients /tmp/replied

comm -23 outputs lines only in file 1 (recipients not in senders). Requires sorted input. grep -oP '<\K[^>]+' uses PCRE lookbehind — match < but don’t include it, capture until >.

Sort find results by modification time (newest first)

find discovers files but has no sort. Chain -printf with sort to order by mtime.

awk '{print $2}' truncates filenames with spaces — Familia Romana_ Lingva…​ becomes Familia. Always use the null-safe or sub() variants below for real data.
epoch sort — space-safe (production version)
# Sort by mtime, strip epoch prefix — handles spaces in filenames
find ~/Downloads -maxdepth 1 -name '*.pdf' -printf '%T@ %p\n' | sort -rn | awk '{sub(/^[^ ]+ /,""); print}'

sub(/[ ]+ /,"") removes everything up to and including the first space (the epoch). {print $2} would split on every space — fatal for Familia Romana_ Lingva Latina.

human-readable timestamps alongside
# ISO 8601 timestamps — readable and lexicographically sortable
find ~/Downloads -maxdepth 1 -name '*.pdf' -printf '%T+ %p\n' | sort -r | head -20

%T+ renders YYYY-MM-DD+HH:MM:SS — no epoch math needed, still sorts correctly as text.

null-safe — the bulletproof version
# Null-delimited: survives any filename (newlines, quotes, unicode)
find ~/Downloads -maxdepth 1 -name '*.pdf' -printf '%T@\t%p\0' | sort -zrn | awk -v RS='\0' -F'\t' '{print $2}'

-printf '%T@\t%p\0' — tab separates epoch from path, null terminates. sort -z sorts null-delimited records. awk -v RS='\0' -F'\t' reads null-terminated, splits on tab — $2 is now the full path regardless of spaces.

stat fallback — portable (BSD/macOS)
# GNU stat equivalent — works where -printf is unavailable
find ~/Downloads -maxdepth 1 -name '*latin*' -exec stat --format='%Y %n' {} + | sort -rn | awk '{sub(/^[^ ]+ /,""); print}'

-exec …​ {} + batches all files into one stat call (faster than \;). On macOS, use stat -f '%m %N' instead of --format='%Y %n'.

File intelligence — size, type, duplicates, age

Beyond finding files — interrogating them.

top 10 largest files in a directory tree
# Size in bytes (-printf %s), human-readable via numfmt
find ~/Downloads -type f -printf '%s\t%p\n' | sort -rn | head -10 | numfmt --to=iec --field=1

numfmt --to=iec --field=1 converts the first field from bytes to K/M/G. sort -rn on raw bytes is exact — ls -lhS rounds and sometimes mis-sorts.

find duplicates by size (fast pre-filter before checksumming)
# Files sharing a byte count — likely duplicates (confirm with md5sum)
find ~/Downloads -type f -printf '%s %p\n' | awk '{seen[$1]++; files[$1]=files[$1] "\n  " $0} END {for (s in seen) if (seen[s]>1) print files[s]}'
find duplicates by content — definitive
# md5sum only files with duplicate sizes (two-pass: fast then precise)
find ~/Downloads -type f -printf '%s\n' | sort | uniq -d | while read -r size; do
  find ~/Downloads -type f -size "${size}c" -exec md5sum {} +
done | sort | uniq -w32 -D

Two-pass: first find duplicate sizes (cheap), then md5sum only those (expensive). uniq -w32 -D compares first 32 chars (the hash) and prints all duplicates.

file type census — what’s actually in this directory?
# Count files by MIME type (not extension — extensions lie)
find ~/Downloads -type f -exec file --mime-type -b {} + | sort | uniq -c | sort -rn

file --mime-type -b reports actual content type. -b suppresses filename. A .pdf that’s really text/html is a failed download.

stale files — untouched for 30+ days
# Files not accessed in 30 days — candidates for cleanup
find ~/Downloads -maxdepth 1 -type f -atime +30 -printf '%A+ %s\t%p\n' | sort | numfmt --to=iec --field=2

-atime 30` = access time older than 30 days. `-printf '%A' shows last access. Useful for Downloads cleanup without deleting something you just renamed.

disk usage by subdirectory — sorted
# Which subdirectories consume the most space?
find . -maxdepth 1 -type d -exec du -sh {} + 2>/dev/null | sort -rh | head -20

Batch operations — rename, move, transform

rename all files — strip spaces, lowercase, normalize unicode
# Dry run — show what would change (remove echo to execute)
find ~/Downloads -maxdepth 1 -type f -name '* *' -print0 | while IFS= read -r -d '' f; do
  dir=$(dirname "$f")
  base=$(basename "$f" | tr ' ' '-' | tr '[:upper:]' '[:lower:]')
  echo mv "$f" "$dir/$base"
done

IFS= read -r -d '' — the holy trinity for null-safe filename reading. IFS= prevents whitespace trimming. -r prevents backslash interpretation. -d '' reads until null.

move files by extension into categorized subdirectories
# Sort Downloads chaos into folders by type
find ~/Downloads -maxdepth 1 -type f -print0 | while IFS= read -r -d '' f; do
  ext="${f##*.}"
  case "$ext" in
    pdf|epub)    dest="books" ;;
    jpg|png|svg) dest="images" ;;
    sh|py|rb)    dest="scripts" ;;
    *)           dest="other" ;;
  esac
  mkdir -p ~/Downloads/"$dest"
  echo mv "$f" ~/Downloads/"$dest"/
done

${f##.} — parameter expansion: strip longest match of . from front, leaving only the extension. No basename or awk needed.

batch convert epub → asciidoc (like your Cicero fetch script)
# Convert all epubs in a directory to asciidoc via pandoc
find . -name '*.epub' -type f -exec sh -c '
  for epub; do
    adoc="${epub%.epub}.adoc"
    pandoc -f epub -t asciidoc "$epub" -o "$adoc" \
      && printf "  → %s (%s lines)\n" "$adoc" "$(wc -l < "$adoc")" \
      || printf "  ✗ failed: %s\n" "$epub"
  done
' _ {} +

-exec sh -c '…​' _ {} + — batch mode. _ fills $0 (script name, discarded). All matched files become $1, $2, …​ iterated by for epub. One sh invocation, not one per file.

xargs power patterns

parallel processing — 4 cores
# Checksum all PDFs in parallel (4 processes)
find ~/Downloads -name '*.pdf' -print0 | xargs -0 -P4 md5sum

-P4 runs 4 md5sum processes simultaneously. -print0 | xargs -0 is the null-safe pipeline — no filename can break it.

batched execution — two arguments at a time
# Compare files pairwise with diff
find . -name '*.adoc' -print0 | xargs -0 -n2 diff --brief

-n2 feeds two arguments per invocation. Useful for pairwise comparisons, copy operations (-n2 with cp), or any command taking exactly two args.

placeholder — insert filename at specific position
# Backup every config file: cp <file> <file>.bak
find /etc -maxdepth 1 -name '*.conf' -print0 | xargs -0 -I{} cp {} {}.bak

-I{} replaces {} with each filename. Slower than + batching (one cp per file) but necessary when the filename must appear in a specific position.

Process substitution — diff without temp files

compare two directory listings
# What files exist in study-A but not study-B?
diff <(find data/d000/education/ciceron-study -type f -name '*.adoc' | sort) \
     <(find data/d000/education/latin-study -type f -name '*.adoc' | sort)

<(cmd) creates a file descriptor from command output. diff sees two "files" — no temp files created, no cleanup needed.

compare file counts across directories
# Side-by-side: file type census of two directories
paste <(find dir1 -type f -exec file --mime-type -b {} + | sort | uniq -c | sort -rn) \
      <(find dir2 -type f -exec file --mime-type -b {} + | sort | uniq -c | sort -rn)

awk, sed, jq

awk — field extraction

print second field (whitespace-delimited)
awk '{print $2}' file.txt
custom delimiter — colon-separated (like /etc/passwd)
awk -F: '{print $1, $3}' /etc/passwd
extract JSON code blocks from AsciiDoc
awk '/\[source,json\]/{getline; if ($0 ~ /^----/) {p=1; next}} p && /^----/{p=0; next} p' file.adoc
field extraction with printf formatting
awk '{printf "%-30s %s\n", $1, $2}' file.txt

sed — stream editing

in-place replacement with verify-before/after
# Before
awk 'NR==73' /etc/ssh/sshd_config
# Change
sed -i '73s/#GSSAPIAuthentication no/GSSAPIAuthentication yes/' /etc/ssh/sshd_config
# After
awk 'NR==73' /etc/ssh/sshd_config
extract line range
sed -n '10,20p' file.txt

sed — line-targeted replacement (verify-before / change / verify-after)

the full pattern: locate → validate → change → verify
# 1. LOCATE: find the line number
grep -n 'adoc-pdf' zsh/.zshrc

# 2. VALIDATE: read the exact line before changing
awk 'NR==1760' zsh/.zshrc

# 3. CHANGE: target by line number — only hits that line
sed -i '1760s/alias adoc-pdf=/alias build-adoc=/' zsh/.zshrc

# 4. VERIFY: confirm change AND check for collateral
grep -n 'build-adoc\|adoc-pdf' zsh/.zshrc

Without the line number prefix (1760s/), sed replaces every match in the file — a shotgun. With it, surgical. The line number comes from grep -n.

multi-line verify — check two specific lines at once
awk 'NR==1218 || NR==1760' zsh/.zshrc
range extraction — NR for surgical reads from large files
# grep found the error at line 44164 — read 50 lines of context
awk 'NR>=44160 && NR<=44210' session-dump.adoc

No head | tail chains. No sed -n '44160,44210p'. One awk, two numbers.

grep -oP with \K — value extraction from key-value logs

extract just the value after a key (Perl regex)
# ISE syslog — extract failure reasons
grep -oP 'FailureReason=\K[^,;]+' /var/log/syslog | sort | uniq -c | sort -rn

# ISE — extract MAC addresses
grep -oP 'Calling-Station-ID=\K[0-9A-Fa-f:.-]+' /var/log/syslog | sort -u

# ISE — extract NAS IPs
grep -oP 'NAS-IP-Address=\K[0-9.]+' /var/log/syslog | sort -u

# ISE — extract device names
grep -oP 'NetworkDeviceName=\K[^,;]+' /var/log/syslog | sort -u

\K resets the match start — everything before \K is required context but excluded from output. [^,;]+ captures until the next delimiter. Pipe to sort -u for unique, sort | uniq -c | sort -rn for counted frequency.

pattern: grep -oP 'KEY=\KVALUE_REGEX' | sort pipeline
# Generic form — works for any key=value log format
grep -oP 'FIELD_NAME=\K[^,;]+' logfile | sort | uniq -c | sort -rn | head -20

jq — JSON processing

extract nested fields
curl -s localhost:8080/stats | jq '.stats.total_files'
filter array by property
jq '.results[] | select(.category == "standards")' response.json
transform to TSV for spreadsheets
jq -r '.[] | [.title, .path] | @tsv' response.json | column -t -s $'\t'
GitHub API + jq — commit history by path
gh api "repos/EvanusModestus/domus-captures/commits?path=docs/&per_page=10" |
  jq -r '.[] | "\(.commit.author.date[:10]) \(.sha[:7]) \(.commit.message | split("\n")[0])"'

Shell Patterns

xargs — when the next command reads arguments, not stdin

Next command reads…​ Use

stdin (awk, grep, wc, sort)

pipe directly

arguments (stat, rm, cp, nvim, git add)

xargs

copy today’s files to backup — -I{} placeholder
mkdir -p /tmp/adoc-backup-$(date +%F) && \
  find . -name "*.adoc" -type f -newermt "$(date +%F)" | \
  xargs -I{} cp {} /tmp/adoc-backup-$(date +%F)/
parallel validation — -P4 runs 4 at a time
find .drafts -name "*.adoc" -type f | xargs -P4 -I{} asciidoctor -o /dev/null {}
null-delimited pipeline — safe for filenames with spaces
find . -name "*.adoc" -type f -print0 | xargs -0 wc -l

Process substitution — <(cmd) treats output as a file

compare tracker state: yesterday vs today
diff <(grep '|' partials/trackers/work/adhoc/carryover.adoc | head -20) \
     <(git show HEAD~1:partials/trackers/work/adhoc/carryover.adoc | grep '|' | head -20)
files on disk vs files in nav — drift detection
diff <(find docs/modules/ROOT/pages/projects/chla/mschapv2-migration -name "*.adoc" -type f | sort) \
     <(grep -oP 'mschapv2-migration/[^[]+\.adoc' docs/modules/ROOT/nav.adoc | sort)

Command substitution — embed output as arguments

open most recently modified file in nvim
nvim "$(find data/ -name '*.adoc' -type f -printf '%T@ %p\n' | sort -rn | awk 'NR==1{print $2}')"
line count across a project
wc -l $(find docs/modules/ROOT -path '*mschapv2*' -name '*.adoc' -type f)

Conditional execution — capture, test, act

open matching files only if they exist
files=$(find .drafts -name 'in*' -type f) && [ -n "$files" ] && nvim $files
open files that contain unchecked items
files=$(grep -rl '\[ \]' .drafts/*.adoc) && [ -n "$files" ] && nvim $files
guard with grep -q — only act if pattern matches
grep -q 'TODO\|FIXME\|\[ \]' "$file" && nvim "$file"

Pattern: $(capture)[ -n ] tests non-empty → && only proceeds if true. grep -q is the idempotent guard — run repeatedly, only opens when there’s work.

Decrypt and open — find .age, decrypt, nvim in one shot

files=$(find . -name "*tcp-clock*.age" -type f) && \
  [ -n "$files" ] && echo "$files" | xargs -I{} decrypt-file {} && \
  nvim $(echo "$files" | sed 's/\.age$//')

Pattern: find .age only (never tries plaintext), sed derives the decrypted path, guard prevents empty nvim. Change the glob to match any project.

tee_clean — color on screen, clean text in file

tee_clean() {
  tee >(sed 's/\x1b\[[0-9;]*m//g' > "$1")
}

# Color output on terminal, stripped in file
jq -C '.' data.json | tee_clean output.json
xq -C '.' data.xml | tee_clean output.json

# Wrap a whole block
{
  echo "=== Summary ==="
  jq -C '.[] | .name' data.json
} | tee_clean summary.txt

The >(cmd) is process substitution — tee writes to stdout AND to the subshell pipe. sed strips ANSI escape sequences (\x1b\[[0-9;]*m) before they hit the file.

Dependency check — verify toolchain in one shot

for cmd in asciidoctor asciidoctor-pdf pandoc rouge d2 mmdc age; do
  printf "%-20s %s\n" "$cmd" "$(command -v $cmd >/dev/null 2>&1 && echo 'OK' || echo 'MISSING')"
done

Pattern: command -v checks if binary exists on PATH. >/dev/null 2>&1 suppresses output — we only care about exit code. Swap the tool list for any project’s dependencies.

printf safety — dashes as data, not options

wrong — printf treats --- as invalid option
printf '---\n\n'
right — %s format string treats --- as data
printf '%s\n\n' '---'

Kill stuck SSH sessions

Find established SSH connections
lsof -i TCP -n -P | awk '/ssh.*ESTABLISHED/ {print $2, $9}'
Kill all stuck SSH sessions to a specific host
lsof -i TCP -n -P | awk '/ssh.*kvm-01.*ESTABLISHED/ {print $2}' | sort -u | xargs kill
Kill ALL stuck SSH sessions
lsof -i TCP -n -P | awk '/ssh.*ESTABLISHED/ {print $2}' | sort -u | xargs kill

lsof -i TCP -n -P lists all TCP connections. awk filters for SSH + ESTABLISHED, prints only the PID ($2). sort -u deduplicates (multiple file descriptors per process). xargs kill sends SIGTERM to each.

File Descriptors & Redirection

The three file descriptors

FD Name Purpose

0

stdin

input to the command

1

stdout

normal output (valid results)

2

stderr

error messages

Split stdout and stderr into separate files

find / -name "*.conf" 1>results.txt 2>errors.txt

Suppress errors — 2>/dev/null

find / -name "*.conf" 2>/dev/null

Merge stderr into stdout — 2>&1

command 2>&1 | grep "pattern"

This sends both stdout and stderr through the pipe. Without 2>&1, only stdout reaches grep — errors print to the terminal and bypass the pipeline.

Heredoc patterns

multi-line input to a command
cat <<'EOF'
Line 1
Line 2
EOF
heredoc commit messages (quotes prevent variable expansion)
git commit -m "$(cat <<'EOF'
feat: add new feature

Multi-line description here.
EOF
)"

Security & Encryption

View encrypted files without writing to disk

pipe age decrypt to bat — nothing touches the filesystem
age --decrypt -i ~/.secrets/.metadata/keys/master.age.key \
  data/d001/projects/mandiant-remediation/findings-status-2026-04-16.adoc.age \
  | bat --language asciidoc --file-name "findings-status-2026-04-16.adoc"

Batch re-encrypt — brace expansion + loop

re-encrypt multiple project files
for f in data/d001/projects/mandiant-remediation/{findings-status,guest-acl-update,siem-report}-2026-04-16.adoc; do
  rm -f "${f}.age" && echo y | encrypt-file "$f"
done
Always rm -f the .age first. If you skip it, encrypt-file prompts about overwrite and may only delete the plaintext without re-encrypting.

Detect stale plaintext — files needing re-encryption

find plaintext newer than its .age counterpart
for f in data/d001/projects/*/*.adoc; do
  age="${f}.age"
  if [ -f "$f" ] && [ -f "$age" ]; then
    pt_mod=$(/usr/bin/stat -c'%Y' "$f")
    age_mod=$(/usr/bin/stat -c'%Y' "$age")
    [ "$pt_mod" -gt "$age_mod" ] && echo "STALE: $f"
  fi
done

Secure delete — shred for sensitive plaintext

shred -u data/d001/projects/mandiant-remediation/man-report.txt
On SSD/NVMe, shred is less effective (wear leveling), but better than rm which only removes the directory entry.

Pre-push audit — find all unencrypted project files

find data/d001/projects -type f ! -name '*.age' ! -name 'README.adoc' ! -name '.gitkeep' ! -name '*.py' | sort

USB-C / Thunderbolt Charging Diagnostics

Full evidence capture to file (one block, timestamped)
{
  echo "=== Power Supply ==="
  cat /sys/class/power_supply/*/status
  echo ""
  cat /sys/class/power_supply/*/type
  echo ""
  echo "=== UPower ==="
  upower -d | grep -E 'state|percentage|energy-rate|voltage'
  echo ""
  echo "=== dmesg (typec/thunderbolt/PD) ==="
  sudo dmesg | grep -iE 'typec|thunderbolt|ucsi|PD|power.delivery|charging' | tail -20

  grep -iE 'thunderbolt|typec|ucsi|^.*upgraded linux ' /var/log/pacman.log | tail -20
} | tee /tmp/INC-$(date +%F)-usbc-charging.txt

Pattern: { } groups commands into a single stdout stream. tee writes to file AND displays on screen. Reusable for any multi-command evidence capture — change the commands inside, keep the structure.
