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-repoinstalled -
Expressions file reviewed — no false positives (e.g., Don Quijote "Angulo el Malo" is in
segunda-parte/texto/texto-011.adoc— the regex targetsangulo-arreolaspecifically 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

Z Fold 7 — Full Workflow Deploy
Z Fold 7 — Full Workflow Deploy
New device connected via ADB (R3GYB0J7YHY, SM_F966U1).
Old Termux state is gone — deploy the full Linux workflow from scratch.
Scope: Termux baseline, SSH, repos (domus-captures, dots-quantum, domus-asciidoc-build, others), gopass v3+v4, stow, build-adoc, mobile aliases.
Prior art:
-
Z Fold 7 Mobile Workflow — phases 0-10 (reference, not repeat)
-
INC-2026-03-16 — gopass/SSH cert failure (lessons: F-Droid only, u0_a385 principals)
Phone File Organization via ADB
Run before Termux setup. Pull all user files to the workstation, organize by category, clean the device.
Verify ADB connection
adb devices -l
Inventory the phone
adb shell ls -la /sdcard/
adb shell ls -la /sdcard/Download/
adb shell ls -la /sdcard/DCIM/Camera/ | wc -l
adb shell ls -laR /sdcard/DCIM/Screenshots/
adb shell ls -laR /sdcard/Pictures/
adb shell ls -laR /sdcard/Documents/
adb shell ls -laR /sdcard/Movies/
adb shell ls -laR /sdcard/Recordings/
adb shell ls -laR /sdcard/Music/
adb shell ls runs on the device — no run-as needed for /sdcard/. Termux’s data dir (/data/data/com.termux/) is not accessible without root.

Lessons learned
-
adb shell run-as com.termuxfails — Termux is not a debuggable package -
adb pushto/data/data/com.termux/fails — requires root -
The bridge is
/sdcard/(shared storage) — ADB can read/write freely -
Always single-quote globs in
adb shellcommands — zsh expands them locally otherwise
Package Audit
Run these on the phone (Termux) or via ssh fold7 before installing anything.

Remove duplicate nvim clones (on phone)
~/.config/domus-nvim was a duplicate clone of ~/.config/nvim.
Remove the duplicate, its data dirs, and the broken symlink inside nvim.
dots-quantum sets NVIM_APPNAME=domus-nvim in zshrc, so nvim looks for ~/.config/domus-nvim/. After removing the duplicate, create a symlink back to ~/.config/nvim/ — without it, nvim falls back to netrw (no config found).

Upgrade stale packages

ADB bootstrap model (for fresh installs)
On a brand new phone with no Termux, the bootstrap splits across two surfaces:
| Surface | What runs here | Why |
|---|---|---|
Phone (Termux) |
|
Only Termux’s own shell can write to its data dir |
Workstation (ADB) |
|
Shared storage is the bridge |
Phone (Termux) |
|
Move from shared storage into Termux home |
adb shell run-as com.termux fails — Termux is not a debuggable package.
adb push to /data/data/com.termux/ fails — requires root.
The only ADB-writable path is /sdcard/ (shared storage).

The phone needs your public key to accept incoming SSH from the workstation. Push via ADB to shared storage, then copy into Termux:
From workstation:
adb push ~/.ssh/id_ed25519_d000.pub /sdcard/authorized_key.pub
On phone (Termux):

SSH — config.d Migration & Vault Cert

✅ Works (gopass sync confirmed) |
— |
Step 1 — Replace flat config with config.d
From workstation — push config.d:
scp -r ~/.ssh/config.d fold7:~/.ssh/
On phone (Termux) — back up the flat config first, then replace with Include:
wc -l ~/.ssh/config
cp ~/.ssh/config ~/.ssh/config.bak.2026-07-01
echo 'Include config.d/*.conf' | tee ~/.ssh/config > /dev/null
chmod 600 ~/.ssh/config
zsh > redirection fails with "file exists" on existing files (clobber protection). Use tee instead of heredoc/redirect.
|
Verify config.d was copied:
ls -la ~/.ssh/config.d/
Verify the modular config loads:
ssh -G fold7 | grep -E 'hostname|user|identityfile|port'
Step 2 — Re-sign Vault SSH cert
The cert expired 2026-03-18 (8hr TTL). Termux user is u0_a385.
On workstation:
ds d000 dev/vault
Check cluster health:
for node in vault-01 vault-02 vault-03; do
printf "%-12s " "$node"
curl -sk "https://$node.inside.domusdigitalis.dev:8200/v1/sys/health" \
| jq -r '"\(if .sealed then "SEALED" else "unsealed" end) \(if .standby then "standby" else "ACTIVE" end) v\(.version)"' \
2>/dev/null || echo "UNREACHABLE"
done
Sign with both principals:
vault write -field=signed_key ssh/sign/domus-client \
public_key=@$HOME/.ssh/id_ed25519_d000.pub \
valid_principals="u0_a385,evanusmodestus" \
cert_type=user | tee /tmp/zfold7-ssh-cert.pub > /dev/null
Verify:
ssh-keygen -L -f /tmp/zfold7-ssh-cert.pub
Confirm u0_a385 AND evanusmodestus appear in Principals.
Push via ADB:
adb push /tmp/zfold7-ssh-cert.pub /sdcard/
On phone (Termux):
cp ~/storage/shared/zfold7-ssh-cert.pub ~/.ssh/id_ed25519_d000-cert.pub
chmod 600 ~/.ssh/id_ed25519_d000-cert.pub
rm ~/storage/shared/zfold7-ssh-cert.pub
Test against a Vault-trusting host:
ssh kvm-02
Cleanup on workstation:
rm -f /tmp/zfold7-ssh-cert.pub
Include BOTH the Termux user AND evanusmodestus in valid_principals.
INC-2026-03-16 root cause: hardcoded old Termux user (u0_a361 vs u0_a385).
|
Step 3 — Verify all connectivity from phone
ssh -T git@github.com
ssh -T git@gitlab.com
ssh -T git@gitea-01
ssh kvm-02 hostname
Workstation SSH config — fold7 entry with Vault cert chain
The fold7 entry needs the full key hierarchy so Vault cert auth is tried first.
Verify current state:
awk '/^Host fold7/,/^$/' ~/.ssh/config.d/80-d000-hosts.conf
Update — delete the old block, append the new one. sed range /,/^$/ is unsafe on the last block (no trailing blank line = wipe).
# Verify before
awk '/^Host fold7/,/^$/' ~/.ssh/config.d/80-d000-hosts.conf
# Delete the old fold7 block (safe: grep first to confirm it exists)
grep -q '^Host fold7' ~/.ssh/config.d/80-d000-hosts.conf && \
sed -i '/^Host fold7$/,/^$/d' ~/.ssh/config.d/80-d000-hosts.conf
# Append the new block
cat >> ~/.ssh/config.d/80-d000-hosts.conf << 'EOF'
Host fold7
HostName 10.50.10.145
Port 8022
IdentityFile ~/.ssh/id_ed25519_vault
CertificateFile ~/.ssh/id_ed25519_vault-cert.pub
IdentityFile ~/.ssh/id_ed25519_d000
EOF
# Verify after
awk '/^Host fold7/,/^$/' ~/.ssh/config.d/80-d000-hosts.conf
Test config resolution:
ssh -G fold7 | grep -E 'hostname|user|identityfile|certificatefile|port'
Delete stale .age, re-encrypt:
rm ~/.ssh/config.d/80-d000-hosts.conf.age
age -e -R ~/.age/recipients/self.txt -o ~/.ssh/config.d/80-d000-hosts.conf.age ~/.ssh/config.d/80-d000-hosts.conf
Verify with forensic stat — .age must be newer and larger than plaintext:
stat --printf='%n\n Size: %s bytes\n Modified: %y\n Permissions: %A (%a)\n Inode: %i\n' ~/.ssh/config.d/80-d000-hosts.conf ~/.ssh/config.d/80-d000-hosts.conf.age
Confirm file type and round-trip integrity:
# Confirm age encryption (magic bytes)
file ~/.ssh/config.d/80-d000-hosts.conf.age
# Decrypt → diff against plaintext (process sub — never writes to disk)
diff <(age -d -i ~/.age/identities/self.txt ~/.ssh/config.d/80-d000-hosts.conf.age) \
~/.ssh/config.d/80-d000-hosts.conf \
&& echo "MATCH" || echo "DRIFT"
Kill stale sessions and mux sockets, then test:
kill $(lsof -i @10.50.10.145 -t) 2>/dev/null
rm -f ~/.ssh/sockets/*10.50.10.145* 2>/dev/null
ssh fold7
Never test SSH with ssh -v fold7 2>&1 | grep — the pipe leaves sessions stuck in ESTABLISHED state. Test with a plain ssh fold7 and observe the passphrase prompt (vault key = working, d000 key = fallback).
|
Troubleshooting
-
Connection refused— sshd not running. Open Termux on phone, runsshd -
Permission deniedwith no key prompt —IdentityFilemissing in SSH config -
Permission deniedafter passphrase —authorized_keysmissing or wrong permissions on phone -
Stale mux socket —
kill $(lsof -i @10.50.10.145 -t) 2>/dev/null && rm -f ~/.ssh/sockets/10.50.10.145 2>/dev/null -
Stuck sessions from piped ssh — never
ssh -v host 2>&1 | grep. Use plainssh hostto test. -
Vault cert rejected — Termux user not in
valid_principals
From-scratch reference (no prior SSH state)
For a phone with no SSH keys at all, push the authorized key and private keys via ADB:
From workstation:
adb push ~/.ssh/id_ed25519_d000.pub /sdcard/authorized_key.pub
On phone (Termux):
mkdir -p ~/.ssh
cat ~/storage/shared/authorized_key.pub >> ~/.ssh/authorized_keys
chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys
rm ~/storage/shared/authorized_key.pub
Then add the fold7 entry with IdentityFile to the workstation SSH config and test.

dots-quantum & domus-nvim
dots-quantum replaces dotfiles-optimus. The phone has dotfiles-optimus with active symlinks. dots-quantum is not cloned on the phone.
Step 1 — Clone dots-quantum (on phone)
git clone git@github.com:EvanusModestus/dots-quantum.git ~/atelier/_projects/personal/dots-quantum
Step 2 — Enumerate stow packages (on phone)
for pkg in ~/atelier/_projects/personal/dots-quantum/*/; do
name=$(basename "$pkg")
[[ "$name" == .* ]] && continue
files=$(find "$pkg" -type f | wc -l)
printf "%-25s %4d files\n" "$name" "$files"
done
Step 3 — Check current symlink targets (on phone)
for f in ~/.zshrc ~/.zshenv ~/.zprofile ~/.gitconfig ~/.fzf ~/.vimrc \
~/.vimrc-minimal ~/.vimrc-ide-alt ~/.vimrc-server \
~/.fdignore ~/.ripgreprc ~/.bashrc ~/.inputrc; do
if [ -L "$f" ]; then
target=$(readlink "$f")
if [ -e "$f" ]; then
printf "%-20s → %s\n" "$(basename "$f")" "$target"
else
printf "%-20s → %s (BROKEN)\n" "$(basename "$f")" "$target"
fi
elif [ -f "$f" ]; then
printf "%-20s (plain file — stow conflict)\n" "$(basename "$f")"
else
printf "%-20s MISSING\n" "$(basename "$f")"
fi
done
Step 4 — Unstow dotfiles-optimus (on phone)
cd ~/atelier/_projects/personal/dotfiles-optimus/base
stow -D -t ~ zsh git fzf fd ripgrep vim
Step 5 — Remove stow conflicts (on phone)
Plain files block stow — move them out of the way:
mv ~/.zshrc ~/.zshrc.bak
mv ~/.config/omp-theme.toml ~/.config/omp-theme.toml.bak
Step 6 — Stow dots-quantum (on phone)
cd ~/atelier/_projects/personal/dots-quantum
stow -t ~ zsh bash git vim fzf fd ripgrep oh-my-posh shell share bin
Step 7 — Verify symlinks point at dots-quantum (on phone)
for f in ~/.zshrc ~/.zshenv ~/.zprofile ~/.gitconfig ~/.fzf ~/.vimrc \
~/.fdignore ~/.ripgreprc ~/.bashrc ~/.inputrc; do
if [ -L "$f" ]; then
printf "%-20s → %s\n" "$(basename "$f")" "$(readlink "$f")"
else
printf "%-20s NOT SYMLINKED\n" "$(basename "$f")"
fi
done
Step 8 — Remove dotfiles-optimus and backups (on phone)
rm -rf ~/atelier/_projects/personal/dotfiles-optimus
rm -f ~/.zshrc.bak
rm -f ~/.config/omp-theme.toml.bak
domus-nvim — pull latest (on phone)
git -C ~/.config/nvim pull
Check LSP availability:
for lsp in lua-language-server rust-analyzer pyright typescript-language-server; do
printf "%-30s " "$lsp"
command -v "$lsp" 2>/dev/null || echo "MISSING"
done
Repo Drift Check — Process & Command Substitution
Compare workstation vs phone repos using diff <(cmd1) <(cmd2).
Process substitution treats command output as a file — no temp files, no pipes.
Compare tracked files (git ls-files)
diff <(git -C ~/atelier/_bibliotheca/domus-captures ls-files | sort) \
<(ssh fold7 'git -C ~/atelier/_bibliotheca/domus-captures ls-files | sort')
No output = identical. Lines with < are workstation-only, > are phone-only.
Compare all repos at once

Process Substitution Patterns
Process substitution <(cmd) creates a temporary file descriptor from command output.
The shell expands it to /dev/fd/NN — any tool that reads files can consume it.

Install yq (required for v4 extraction)
pkg install yq
yq --version
Clone + mount v4 store
gopass mounts add takes a local path, not a git URL. Clone first, then mount:
git clone git@github.com:EvanusModestus/gopass-v4.git ~/.local/share/gopass/stores/v4
gopass mounts add v4 ~/.local/share/gopass/stores/v4
Do NOT use gopass edit or manually edit gopass config files — it breaks the store. Always use gopass mounts add. And make sure you cd ~ first — gopass interprets relative paths from $PWD.

Sync and verify:
gopass sync
gopass ls v4 | head -20
Verify structured YAML extraction
gopass show v4/domains/d000/identity/ssh/github | yq 'keys'
gopass show v4/domains/d000/identity/ssh/github | yq '.credentials.ssh | keys'

Push GPG key via ADB from workstation:
gpg --export-secret-keys --armor > /tmp/gpg-private.asc
adb push /tmp/gpg-private.asc /sdcard/
rm /tmp/gpg-private.asc
On phone (Termux):
gpg --import ~/storage/shared/gpg-private.asc
rm ~/storage/shared/gpg-private.asc
Then clone and mount both stores:
git clone git@github.com:EvanusModestus/gopass-v3.git ~/.local/share/gopass/stores/v3
gopass mounts add v3 ~/.local/share/gopass/stores/v3
git clone git@github.com:EvanusModestus/gopass-v4.git ~/.local/share/gopass/stores/v4
gopass mounts add v4 ~/.local/share/gopass/stores/v4

Device Registration
Register the Z Fold 7 in SSH config, Vault PKI, and gopass v4. Modeled on the 2026-06-30 android-vault-cert and gopass-v4-standardization workflows.
Step 0 — Discover device identity
From workstation (phone connected via ADB):
adb shell 'ip addr show wlan0' | awk '/inet / {print $2}; /link\/ether/ {print $2}'
Record:
-
IP:
10.50.10.145(DHCP — will change) -
MAC:
9c:83:06:ce:89:46 -
Model:
SM_F966U1(Samsung Z Fold 7) -
ADB serial:
R3GYB0J7YHY
Step 1 — Add to SSH config
Add to ~/.ssh/config.d/80-d000-hosts.conf:
cat >> ~/.ssh/config.d/80-d000-hosts.conf << 'EOF'
Host fold7
HostName 10.50.10.145
Port 8022
EOF
Verify:
awk '/fold7/,/^$/' ~/.ssh/config.d/80-d000-hosts.conf
| DHCP address — set a reservation on VyOS or update the IP after each reconnect. Consider adding a DHCP static mapping: |
# On VyOS (configure mode):
# set service dhcp-server shared-network-name DATA subnet 10.50.10.0/24 static-mapping zfold7 mac-address 9c:83:06:ce:89:46
# set service dhcp-server shared-network-name DATA subnet 10.50.10.0/24 static-mapping zfold7 ip-address 10.50.10.145
Delete stale .age first, then re-encrypt:
rm ~/.ssh/config.d/80-d000-hosts.conf.age
age -e -R ~/.age/recipients/self.txt -o ~/.ssh/config.d/80-d000-hosts.conf.age ~/.ssh/config.d/80-d000-hosts.conf
Step 2 — Source Vault credentials + verify cluster health
ds d000 dev/vault
for node in vault-01 vault-02 vault-03; do
printf "%-12s " "$node"
curl -sk "https://$node.inside.domusdigitalis.dev:8200/v1/sys/health" \
| jq -r '"\(if .sealed then "SEALED" else "unsealed" end) \(if .standby then "standby" else "ACTIVE" end) v\(.version)"' \
2>/dev/null || echo "UNREACHABLE"
done
If any node is sealed, unseal with gopass v4:
gopass show v4/domains/d000/identity/vault/cluster 2>/dev/null \
| sed -n '/^type:/,$ p' | yq -r '.credentials.unseal."key-1"' | wl-copy
vault operator unseal -address="https://<node>.inside.domusdigitalis.dev:8200"
wl-copy ''
gopass show v4/domains/d000/identity/vault/cluster 2>/dev/null \
| sed -n '/^type:/,$ p' | yq -r '.credentials.unseal."key-2"' | wl-copy
vault operator unseal -address="https://<node>.inside.domusdigitalis.dev:8200"
wl-copy ''
Verify token:
vault status | grep -E 'Sealed|HA Mode|Active Node'
vault token lookup | awk '/display_name|expire_time|policies/'
Step 3 — Issue EAP-TLS client cert
Verify PKI role:
vault read -format=json pki_int/roles/domus-client \
| jq '.data | {allowed_domains, organization, ou, key_type, key_bits, max_ttl}'
Export CA chain:
vault read -field=certificate pki/cert/ca > /tmp/vault-root-ca.pem
vault read -field=certificate pki_int/cert/ca > /tmp/vault-intermediate-ca.pem
openssl x509 -in /tmp/vault-root-ca.pem -noout -subject -dates
openssl x509 -in /tmp/vault-intermediate-ca.pem -noout -subject -issuer -dates
openssl verify -CAfile /tmp/vault-root-ca.pem /tmp/vault-intermediate-ca.pem
Issue cert:
vault write -format=json pki_int/issue/domus-client \
common_name="zfold7.inside.domusdigitalis.dev" \
ttl="8760h" > /tmp/zfold7-cert.json
Extract and verify:
jq -r '.data.certificate' /tmp/zfold7-cert.json > /tmp/zfold7.pem
jq -r '.data.private_key' /tmp/zfold7-cert.json > /tmp/zfold7-key.pem
jq -r '.data.ca_chain[]' /tmp/zfold7-cert.json > /tmp/zfold7-ca-chain.pem
openssl x509 -in /tmp/zfold7.pem -noout -subject -issuer -dates
openssl verify -CAfile /tmp/vault-root-ca.pem -untrusted /tmp/vault-intermediate-ca.pem /tmp/zfold7.pem
Bundle as PKCS12:
openssl pkcs12 -export \
-in /tmp/zfold7.pem \
-inkey /tmp/zfold7-key.pem \
-certfile /tmp/zfold7-ca-chain.pem \
-out /tmp/zfold7.p12 \
-name "Domus EAP-TLS"
Verify bundle:
openssl pkcs12 -in /tmp/zfold7.p12 -info -nokeys 2>/dev/null | grep -E 'subject|issuer'
Step 4 — Push certs to phone
adb push /tmp/vault-root-ca.pem /sdcard/Download/
adb push /tmp/vault-intermediate-ca.pem /sdcard/Download/
adb push /tmp/zfold7.p12 /sdcard/Download/
Step 5 — Install on Android
Install CA certs (root first, then intermediate):
-
Settings → Security → More security settings → Encryption & credentials
-
Install a certificate → Certificado de CA →
vault-root-ca.pem→ Name: "Domus Root CA" -
Repeat for
vault-intermediate-ca.pem→ Name: "Domus Intermediate CA"
Install client cert:
-
Install a certificate → Certificado de Wi-Fi →
zfold7.p12 -
Enter PKCS12 password
-
Name: "Domus EAP-TLS"
| Do NOT use "Cert. de usuario de aplic. y VPN" — WiFi supplicant does not read from that store. |
Step 6 — Disable MAC randomization + configure WiFi
-
Settings → WiFi → Domus-Secure (gear icon)
-
Advanced → Tipo de dirección MAC → MAC del teléfono
WiFi profile:
| Campo | Valor |
|---|---|
Red |
Domus-Secure |
Seguridad |
WPA2/WPA3-Enterprise |
Método EAP |
TLS |
Certificado CA |
Domus Root CA |
Certificado de usuario |
Domus EAP-TLS |
Identidad |
|
Identidad anónima |
|
Dominio |
|
Verify real MAC after connecting:
adb shell 'ip addr show wlan0' | awk '/link\/ether/{print $2}'
Samsung OUI starts with 00:, 04:, 14:, 1C:, 20:, 9C:. If you see 66:xx, randomization is still on.
Step 7 — Sign SSH cert for Termux
Get the Termux username first (from Termux on phone: whoami).
ds d000 dev/vault
vault write -field=signed_key ssh/sign/domus-client \
public_key=@$HOME/.ssh/id_ed25519_d000.pub \
valid_principals="<termux-user>,evanusmodestus" \
cert_type=user > /tmp/zfold7-ssh-cert.pub
ssh-keygen -L -f /tmp/zfold7-ssh-cert.pub
Push to phone via ADB (SSH may not be configured yet):
adb push /tmp/zfold7-ssh-cert.pub /sdcard/
On phone (Termux):
cp ~/storage/shared/zfold7-ssh-cert.pub ~/.ssh/id_ed25519-cert.pub
chmod 600 ~/.ssh/id_ed25519-cert.pub
rm ~/storage/shared/zfold7-ssh-cert.pub
Include BOTH the Termux user AND evanusmodestus in valid_principals. INC-2026-03-16 root cause was hardcoded old Termux user (u0_a361).
|
Step 8 — Create gopass v4 entry
Entry path: v4/domains/d000/network/devices/mobile/zfold7
gopass edit v4/domains/d000/network/devices/mobile/zfold7
Paste this YAML (update IP/Termux user after confirming):
type: "mobile"
hostname: "zfold7"
model: "SM_F966U1"
serial: "R3GYB0J7YHY"
os: "Android + Termux"
mac:
wifi: "9c:83:06:ce:89:46"
ip: "10.50.10.145"
vlan: "10"
location: "Domus Digitalis"
credentials:
ssh:
_use: "Termux sshd — port 8022, ed25519 key"
port: "8022"
user: "<termux-user>"
key_file: "~/.ssh/id_ed25519"
eap-tls:
_use: "802.1X WiFi — Vault-issued cert"
cn: "zfold7.inside.domusdigitalis.dev"
ca: "Domus Root CA + Intermediate"
identity: "anonymous@inside.domusdigitalis.dev"
cert_ttl: "8760h"
network:
ssid: "Domus-Secure"
security: "WPA2/WPA3-Enterprise EAP-TLS"
mac_randomization: "disabled"
pki:
client_cert_cn: "zfold7.inside.domusdigitalis.dev"
issuer: "pki_int/issue/domus-client"
ssh_signer: "ssh/sign/domus-client"
created: "2026-07-01"
updated: "2026-07-01"
Verify:
gps v4/domains/d000/network/devices/mobile/zfold7 'keys'
gps v4/domains/d000/network/devices/mobile/zfold7 '.credentials | keys'
gps v4/domains/d000/network/devices/mobile/zfold7 -r '.hostname + " (" + .ip + ")"'
gps v4/domains/d000/network/devices/mobile/zfold7 -r '.credentials.ssh.port'
gps v4/domains/d000/network/devices/mobile/zfold7 -r '.mac.wifi'
Step 9 — Verify ISE authentication
dsource d000 dev/network/ise
MAC="9C:83:06:CE:89:46"
full-endpoint-profile.sh "$MAC"
ISE Live Logs should show:
-
Authentication method:
EAP-TLS -
Subject CN:
zfold7.inside.domusdigitalis.dev -
VLAN assigned:
10(Data) -
Result:
PASS
Step 10 — Cleanup
rm -f /tmp/zfold7-cert.json /tmp/zfold7.pem /tmp/zfold7-key.pem \
/tmp/zfold7-ca-chain.pem /tmp/zfold7.p12 /tmp/zfold7-ssh-cert.pub \
/tmp/vault-root-ca.pem /tmp/vault-intermediate-ca.pem
Delete from phone after installation:
adb shell 'rm -f /sdcard/Download/vault-root-ca.pem /sdcard/Download/vault-intermediate-ca.pem /sdcard/Download/zfold7.p12'

Private key hygiene
The PKCS12 file contains the private key. After installing on the phone, delete from |
SSH Session Forensics
Tools for identifying, inspecting, and killing stuck SSH sessions.

Reading the output
| PID | State | Port | Analysis |
|---|---|---|---|
3294350 |
|
44758 |
Dead — remote closed, local hasn’t cleaned up. Safe to kill. |
3688247 |
|
52086 |
Active standalone session |
3725216 |
|
45236 |
Mux master — shares DEVICE |
3727906 |
|
45236 |
Mux child — rides on 3725216’s socket (same DEVICE, same port) |
Key forensic tells:
-
CLOSE_WAIT— remote side closed (FINsent), local process hasn’t calledclose(). Always safe to kill. -
Same DEVICE number — two PIDs sharing a socket = mux master + child. Kill master and child dies too.
-
Recv-Q > 0inCLOSE_WAIT— data arrived after remote closed. The session is dead, buffered data is unreadable. -
fd=3uvsfd=4u—3is the standard SSH socket fd.4often means the connection was inherited or reopened (mux).
Surgical kill — target only dead sessions
# lsof approach — kill only CLOSE_WAIT PIDs
lsof -i @10.50.10.145 -n -P | awk '/CLOSE_WAIT/ {print $2, $NF}'
kill $(lsof -i @10.50.10.145 -n -P | awk '/CLOSE_WAIT/ {print $2}')
# ss approach — extract PID from CLOSE_WAIT using awk match() capture group
kill $(ss -tnp dst 10.50.10.145 | awk '/CLOSE-WAIT/ {match($0,/pid=([0-9]+)/,a); print a[1]}')
The awk match($0, /pid=([0-9]+)/, a) captures the PID from ss’s `pid=3294350 format into a[1] — no grep | sed | cut chain needed.
# Verify dead session is gone
lsof -i @10.50.10.145 -n -P | awk '/CLOSE_WAIT/ {print $2}' && echo "STILL ALIVE" || echo "CLEAN"
Graduated kill — full sequence
Always inspect before killing. Never kill -9 first.
# 1. Inspect — what are we about to kill?
lsof -i @10.50.10.145 -n -P
# 2. Kill only dead sessions (CLOSE_WAIT)
kill $(lsof -i @10.50.10.145 -n -P | awk '/CLOSE_WAIT/ {print $2}')
# 3. If killing ALL sessions — graceful SIGTERM first
kill $(lsof -i @10.50.10.145 -t)
# 4. Verify
lsof -i @10.50.10.145 -t && echo "STILL ALIVE" || echo "CLEAN"
# 5. Force only if graceful failed — SIGKILL (no cleanup, mux socket orphaned)
kill -9 $(lsof -i @10.50.10.145 -t) 2>/dev/null
# 6. Clean up orphaned mux sockets after force kill
rm -f ~/.ssh/sockets/*10.50.10.145* 2>/dev/null
Mux-aware kill patterns
# Get PIDs with context — identify master vs child
lsof -i @10.50.10.145 -n -P | awk 'NR>1 {printf "PID %-8s DEVICE %-10s %-12s %s\n", $2, $8, $NF, $9}'
# Kill mux master (children die automatically)
kill $(lsof -i @10.50.10.145 -n -P | awk '/ESTABLISHED/ {print $2}' | sort -u | head -1)
# Kill all except the newest session
kill $(lsof -i @10.50.10.145 -t | sort -n | head -n -1)
# Kill only sessions older than the mux master (stale pre-mux connections)
kill $(lsof -i @10.50.10.145 -n -P | awk '/CLOSE_WAIT/ || /ESTABLISHED/ && $8 != latest_device {print $2}')
Combined audit — one command

SSH escape sequences (inside a stuck session)
If you’re inside a hung SSH session and the terminal is frozen:
~. # Disconnect (must be first char on a new line — hit Enter first)
~? # List all escape sequences
~# # List forwarded connections
~C # Open command line (add/remove port forwards)
~& # Background SSH (when waiting for connections to close)
ss vs lsof vs fuser — when to use which
| Tool | Strength | Use when |
|---|---|---|
|
Fast, kernel-level socket state, timer info, no privilege needed |
Quick check — "is there a connection to X?" |
|
Maps files/sockets to PIDs, full process context, fd details |
Need to kill — "which PID owns this connection?" |
|
Minimal — just PIDs for a port or file |
One-liner kill: |
Vault SSH cert principals — u0_a385 fix
The workstation’s vault-ssh-sign script uses a fixed principal list. It had u0_a361 (old Termux user) but not u0_a385 (current). Termux sshd maps all connections to the local user (u0_a385), so cert auth fails if that principal is missing.
Re-sign with updated principals:
ds d000 dev/vault
vault write -field=signed_key ssh/sign/domus-client \
public_key=@$HOME/.ssh/id_ed25519_vault.pub \
valid_principals="Administrator,admin,adminerosado,ansible,evanusmodestus,gabriel,root,u0_a385" \
cert_type=user | tee ~/.ssh/id_ed25519_vault-cert.pub > /dev/null
Verify:
ssh-keygen -L -f ~/.ssh/id_ed25519_vault-cert.pub | grep -A 15 'Principals'
Permanent fix — update the script in dots-quantum:
cat ~/.local/bin/vault-ssh-sign
# Find the valid_principals line and add u0_a385, remove u0_a361
Test after re-sign:
# Kill stuck sessions + stale sockets
kill $(lsof -i @10.50.10.145 -t) 2>/dev/null
rm -f ~/.ssh/sockets/*10.50.10.145* 2>/dev/null
ssh -v fold7 2>&1 | grep -E 'Offering|Accepted'
Android UID pattern
Termux user follows Android’s app UID scheme: u0_a[0-9]+
-
u0— primary Android user (user 0) -
a— app (alwaysa, never other letters) -
[0-9]+— sequentially assigned numeric ID
Changes on app reinstall. Always verify with ssh fold7 'whoami' before signing certs.

Environment Variables — Linux Quality of Life Reference
Captured 2026-07-01 from P16g (Arch Linux, Hyprland, tmux, domus-nvim). Reference for troubleshooting, new machine setup, and development.
Wayland / Compositor — hyprctl, clipboard, display
| Variable | Value | What Breaks Without It |
|---|---|---|
|
|
All |

|
|
|
|
XWayland apps (some Electron apps, |

Terminal 24-bit color — without it, Neovim and bat fall back to 256-color |
|

Notifications, secrets service (gnome-keyring), polkit prompts |
tmux Environment Problem + Fix
tmux server runs independently of the compositor. Panes don’t inherit Hyprland variables unless explicitly pushed.
for var in WAYLAND_DISPLAY DISPLAY HYPRLAND_INSTANCE_SIGNATURE XDG_RUNTIME_DIR; do
tmux setenv "$var" "${(P)var}"
done
${(P)var} — zsh indirect parameter expansion. Takes the string in $var (e.g. "WAYLAND_DISPLAY") and expands it as a variable name ($WAYLAND_DISPLAY). Bash equivalent: ${!var}.
for var in WAYLAND_DISPLAY DISPLAY HYPRLAND_INSTANCE_SIGNATURE XDG_RUNTIME_DIR; do
eval "$(tmux showenv "$var" 2>/dev/null)"
done
tmux showenv # all (- prefix = removed)
tmux showenv | grep -v '^-' # active only
tmux showenv WAYLAND_DISPLAY # single variable
tmux setenv -u VARNAME # remove a variable
Variables prefixed with - in tmux showenv (e.g. -SSH_CONNECTION, -WINDOWID) are explicitly removed — tmux strips them so panes don’t inherit stale values.

Laptop Panel Black After Sleep — Root Cause + Fix
Root Cause
hypridle sets brightness to 0 on timeout/lid close. On resume, brightnessctl -r tries to restore but fails silently because the backlight sysfs file is root:root 0644 — user can’t write to it.
# The chain:
on-timeout → brightnessctl -s set 0 ← saves + dims (works initially)
on-resume → brightnessctl -r ← restore fails — permission denied, silent
lid close → brightnessctl -s set 0 ← same
lid open → brightnessctl -r ← same silent failure
# Current permissions — user has no write access
-rw-r--r-- root root /sys/class/backlight/intel_backlight/brightness
Fix — udev Rule + Video Group
# 1. Add user to video group
sudo usermod -aG video evanusmodestus
# 2. Create udev rule — sets backlight group to video with g+w on boot
echo 'ACTION=="add", SUBSYSTEM=="backlight", RUN+="/bin/chgrp video /sys/class/backlight/%k/brightness", RUN+="/bin/chmod g+w /sys/class/backlight/%k/brightness"' \
| sudo tee /etc/udev/rules.d/90-backlight.rules
Reboot required — group membership only applies to new login sessions.
Verify After Reboot
# Confirm group membership
groups | grep video
# Confirm permissions changed
ls -la /sys/class/backlight/intel_backlight/brightness
# Should show: -rw-rw-r-- root video
# Confirm brightnessctl works without sudo
brightnessctl set 50%
brightnessctl set 100%
Hyprland Config Reference
From ~/.config/hypr/hypridle.conf:
# Timeout dimming (saves + restores)
on-timeout = brightnessctl -s set 10%
on-resume = brightnessctl -r
# Deep sleep — full blackout
on-timeout = brightnessctl -s set 0
on-resume = brightnessctl -r
From ~/.config/hypr/hyprland.conf:
# Lid switch — lock + blackout / restore
bindl = , switch:on:Lid Switch, exec, loginctl lock-session && brightnessctl -s set 0
bindl = , switch:off:Lid Switch, exec, brightnessctl -r
# Manual brightness keys
bindle = , XF86MonBrightnessUp, exec, brightnessctl set +5%
bindle = , XF86MonBrightnessDown, exec, brightnessctl set 5%-
# Sleep resume — re-enable monitor
after_sleep_cmd = hyprctl keyword monitor "eDP-1, preferred, auto, 2" && hyprctl dispatch dpms on
All of these depend on brightnessctl having write access to the backlight device.
Emergency Recovery (Before udev Fix Is Applied)
# Quick fix — needs sudo
sudo brightnessctl set 50%
# Hyprland DPMS toggle (if compositor issue, not backlight)
hyprctl dispatch dpms off eDP-1 && sleep 1 && hyprctl dispatch dpms on eDP-1
# Force mode reset

Steam Installation — AppArmor Hardened
Steam Installation — AppArmor Hardened
Pacman-based Steam install on modestus-p16g (Arch, RTX 5090, AppArmor). Replaces the default unconfined AppArmor profile with actual confinement — denies access to credential stores (~/.ssh, ~/.gnupg, ~/.age, gopass) while allowing GPU, network, and game directories. Includes clean uninstall procedure and GMod Lua mods for programming with Gabriel.

Enable unprivileged user namespaces (scoped, not persistent)
Steam’s sandbox requires unprivileged user namespaces. This machine intentionally disables them via /etc/sysctl.d/99-hardening.conf (container escape mitigation). Rather than undo that hardening permanently, we use a wrapper script that enables the sysctl only while Steam is running.
|
Why not a persistent drop-in?
A persistent |
~/.local/bin/steam-safe — wrapper script#!/bin/bash
# steam-safe — launch Steam with unprivileged user namespaces enabled,
# disable them again on exit.
#
# Why: Steam requires kernel.unprivileged_userns_clone=1 for its sandbox.
# This machine disables it by default (99-hardening.conf) because
# user namespaces have been a privilege escalation vector:
# - CVE-2022-0185: heap overflow via user namespace
# - CVE-2023-2640: Ubuntu OverlayFS user namespace escalation
# This script limits the exposure window to the Steam session only.
set -euo pipefail
enable_userns() { sudo sysctl -q -w kernel.unprivileged_userns_clone=1; }
disable_userns() { sudo sysctl -q -w kernel.unprivileged_userns_clone=0; }
# Ensure we disable on exit, even if Steam crashes
trap disable_userns EXIT
echo "[steam-safe] Enabling unprivileged user namespaces..."
enable_userns
echo "[steam-safe] Launching Steam..."
/usr/bin/steam "$@"
# trap EXIT handles disable_userns
echo "[steam-safe] Steam exited. User namespaces disabled."
Install the wrapper:
# Create the script
cat > ~/.local/bin/steam-safe << 'SCRIPT'
#!/bin/bash
set -euo pipefail
enable_userns() { sudo sysctl -q -w kernel.unprivileged_userns_clone=1; }
disable_userns() { sudo sysctl -q -w kernel.unprivileged_userns_clone=0; }
trap disable_userns EXIT
echo "[steam-safe] Enabling unprivileged user namespaces..."
enable_userns
echo "[steam-safe] Launching Steam..."
/usr/bin/steam "$@"
echo "[steam-safe] Steam exited. User namespaces disabled."
SCRIPT
# Make executable
chmod +x ~/.local/bin/steam-safe
# Verify
which steam-safe && steam-safe --help 2>&1 | head -3
From now on, launch Steam with steam-safe instead of steam. On exit (clean or crash), the trap EXIT reverts the sysctl automatically.

Teaching Gabriel: defense in depth
This is a real-world example of defense in depth — multiple independent layers of security:
No single layer is perfect. Together, they reduce the attack window from "always open" to "open only during gameplay, and only for Steam." |

Run Steam once before applying AppArmor — it needs to bootstrap its runtime:

This creates ~/.local/share/Steam/ — the Steam runtime directory. AppArmor paths below reference this directory, so it must exist first.

AppArmor Hardening
The default /etc/apparmor.d/steam profile ships unconfined — it names the binary but enforces nothing. Replace it with an actual confinement profile.
Why confine Steam?
Steam runs arbitrary third-party code (game binaries, workshop addons, Proton/Wine layers). It has:
-
Write access to your entire
$HOMEby default -
Network access (multiplayer, workshop downloads, telemetry)
-
Access to input devices, GPU, audio
Confinement limits blast radius: a malicious workshop addon or compromised game binary can’t read ~/.ssh/, ~/.gnupg/, gopass stores, or .age identities.
Profile

Back up the existing profile before replacing:
|
/etc/apparmor.d/steam — enforcing profile# AppArmor profile for Steam (Arch Linux, pacman install)
# Replaces the default unconfined placeholder.
# Strategy: allow Steam's own directories + GPU/audio/input + network.

| 1 | Starts in complain mode — logs violations without blocking. Switch to enforce after testing. |
| 2 | Explicit denies take precedence even if a broader allow would match. These protect credential stores, secrets, and identity material. |
Load and verify
# Parse the profile for syntax errors
sudo apparmor_parser -Q /etc/apparmor.d/steam
# Load the profile
sudo apparmor_parser -r /etc/apparmor.d/steam
# Verify it loaded in complain mode
sudo aa-status | grep steam
Complain-to-enforce workflow
Run Steam in complain mode first. Play GMod, install workshop addons, test multiplayer. Then review what was logged:
# Check for AppArmor denials (complain mode logs as ALLOWED but flags them)
sudo dmesg | grep -i 'apparmor.*steam' | tail -20
# Or use the audit log
sudo journalctl -k | grep -i 'apparmor.*steam' | tail -20
If no unexpected denials appear after a session or two, switch to enforce:
# Edit the profile: change flags=(complain) to flags=(enforce)
sudo sed -i 's/flags=(complain)/flags=(enforce)/' /etc/apparmor.d/steam
# Verify the change
awk '/^profile steam/' /etc/apparmor.d/steam
# Reload
sudo apparmor_parser -r /etc/apparmor.d/steam
sudo aa-status | grep steam
|
Teaching point: complain vs enforce
AppArmor has two active modes. Complain logs policy violations to the kernel ring buffer but allows them — it’s an observation mode. Enforce blocks violations and logs them. Always deploy new profiles in complain first; a wrong deny in enforce mode will silently break Steam with cryptic errors. The kernel log ( |
Clean Uninstall
Full reversal — leaves no orphaned packages, no residual config, no dangling AppArmor profile, no security relaxation.
Step 1: Remove Steam package and orphaned dependencies
# Remove Steam and any dependencies that nothing else needs
sudo pacman -Rns steam
# Check if lib32-vulkan-icd-loader is still needed by anything else
pactree -r lib32-vulkan-icd-loader
# If only Steam needed it:
sudo pacman -Rns lib32-vulkan-icd-loader
|
Why
-Rns instead of -R?
|
Step 2: Remove steam-safe wrapper
rm ~/.local/bin/steam-safe
No sysctl drop-in to remove — the wrapper enabled user namespaces only during runtime. 99-hardening.conf was never modified, so kernel.unprivileged_userns_clone=0 remains enforced on boot and between sessions.
Step 3: Remove user data
# See what Steam left behind
du -sh ~/.local/share/Steam/ ~/.steam/ ~/.config/unity3d/ 2>/dev/null
# Remove it
rm -rf ~/.local/share/Steam/ ~/.steam/ ~/.steampath ~/.steampid
rm -rf ~/.config/unity3d/
rm -rf ~/.config/cef_user_data/
# Remove desktop entries Steam may have created
rm -f ~/.local/share/applications/steam*.desktop
rm -f ~/.local/share/icons/hicolor/*/apps/steam*.png 2>/dev/null
# Verify nothing remains
find ~ -maxdepth 3 -iname '*steam*' -not -path '*/.local/share/Trash/*' 2>/dev/null
Step 4: Remove AppArmor profile
# Unload the profile from the kernel
sudo apparmor_parser -R /etc/apparmor.d/steam
# Remove the profile file and backup
sudo rm /etc/apparmor.d/steam /etc/apparmor.d/steam.unconfined.bak
# Remove local overrides if any were created
sudo rm -f /etc/apparmor.d/local/steam
# Verify
sudo aa-status | grep steam # should return nothing
Step 5: Verify clean state
# No steam packages
pacman -Q | grep -i steam
# No steam processes
pgrep -a steam
# No steam files in home
find ~ -maxdepth 3 -iname '*steam*' 2>/dev/null
# No apparmor profile
ls /etc/apparmor.d/steam 2>/dev/null
# User namespaces still hardened
sysctl kernel.unprivileged_userns_clone # should be 0
# No wrapper script
which steam-safe 2>/dev/null # should return nothing
Troubleshooting
Common issues from the Arch Wiki, filtered for this setup (NVIDIA, Arch, pacman install).
Steam runtime library conflicts
Steam bundles its own Ubuntu-based runtime libraries. If a game crashes at launch, the bundled library may conflict with a system library.
# Check what Steam is loading from its runtime vs system
for i in $(pgrep steam); do
awk '/\.local/{print $NF}' /proc/$i/maps
done | sort -u
# If a game crashes, check its specific library requirements
ldd ~/.steam/root/steamapps/common/<GAME>/game_executable 2>&1 | grep 'not found'
|
The
LD_PRELOAD override mechanismThe |
Game crashes with DxvkError (Vulkan conflict)
If a game crashes with terminate called after throwing an instance of 'dxvk::DxvkError', conflicting Vulkan drivers are installed. Verify only NVIDIA Vulkan drivers are present:
# Should show ONLY nvidia-related vulkan packages, no intel/amd
pacman -Q | grep -i vulkan
# Expected: vulkan-icd-loader, lib32-vulkan-icd-loader (loaders only — drivers come from nvidia-utils)
Games freeze at start when focused (NVIDIA + Xorg)
Known issue with ForceFullCompositionPipeline + specific NVIDIA driver versions under Xorg. The game runs in the background but freezes when focused.
Fix: disable ForceFullCompositionPipeline or use Wayland (Hyprland on this machine avoids this entirely).
Debugging output
Steam no longer redirects stdout/stderr to /tmp/dumps/ by default. Launch from terminal to capture output:
# Capture Steam output for debugging
steam 2>&1 | tee /tmp/steam-debug-$(date +%F).log
AppArmor denials breaking Steam
If Steam or a game misbehaves after switching to enforce mode, check the kernel log:
# Real-time AppArmor denial monitoring
sudo dmesg -w | grep --line-buffered 'apparmor.*DENIED'
# Or check journal
sudo journalctl -k --since "1 hour ago" | grep -i 'apparmor.*steam'
To temporarily switch back to complain for debugging:
sudo aa-complain /etc/apparmor.d/steam
# Test Steam, then re-enforce:
sudo aa-enforce /etc/apparmor.d/steam
GMod Lua Curriculum
Building on the existing HUD addon and 6-weapon arsenal deployed on 2026-06-28 (see concern gabriel-lua-gmod), these mods are designed to teach programming concepts through gameplay. Each mod is a self-contained lesson — deploy one per session, talk through the code, then let him experiment.

Phase 1: Chat Commands
A chat command processor — type !spawn zombie 5 in chat and it spawns 5 zombies. Teaches string splitting, conditionals, and the hook system.
lua/autorun/server/gabriel_commands.lua-- GABRIEL'S COMMAND SYSTEM
-- Type !help in chat to see all commands
local COMMANDS = {} (1)
-- Register a command: name, function, description
local function RegisterCommand(name, fn, desc) (2)
COMMANDS[name] = {run = fn, help = desc}
end
-- ── Commands ──
RegisterCommand("spawn", function(ply, args) (3)
local npcType = args[1] or "npc_zombie"
local count = tonumber(args[2]) or 1
count = math.Clamp(count, 1, 10) (4)
for i = 1, count do
local npc = ents.Create(npcType)
if IsValid(npc) then
local pos = ply:GetEyeTrace().HitPos + Vector(0, 0, 10) (5)
+ Vector(math.random(-50, 50), math.random(-50, 50), 0)
npc:SetPos(pos)
npc:Spawn()
end
end
ply:ChatPrint("[CMD] Spawned " .. count .. "x " .. npcType)
end, "!spawn <npc_type> <count> — spawn NPCs where you look")
RegisterCommand("god", function(ply, args)
if ply:HasGodMode() then
ply:GodDisable()
ply:ChatPrint("[CMD] God mode OFF")
else
ply:GodEnable()
ply:ChatPrint("[CMD] God mode ON")
end
end, "!god — toggle god mode")
RegisterCommand("speed", function(ply, args)
local mult = tonumber(args[1]) or 2
mult = math.Clamp(mult, 0.5, 10)
ply:SetRunSpeed(500 * mult) (6)
ply:SetWalkSpeed(200 * mult)
ply:ChatPrint("[CMD] Speed set to " .. mult .. "x")
end, "!speed <multiplier> — change move speed")
RegisterCommand("cleanup", function(ply, args)
local removed = 0
for _, ent in ipairs(ents.GetAll()) do
if ent:IsNPC() then
ent:Remove()
removed = removed + 1
end
end
ply:ChatPrint("[CMD] Removed " .. removed .. " NPCs")
end, "!cleanup — remove all NPCs")
RegisterCommand("help", function(ply, args)
ply:ChatPrint("── Gabriel's Commands ──")
for name, cmd in SortedPairs(COMMANDS) do
ply:ChatPrint(" " .. cmd.help)
end
end, "!help — show this list")
-- ── The Hook — this connects chat to our commands ── (7)
hook.Add("PlayerSay", "GabrielCommands", function(ply, text)
if text:sub(1, 1) ~= "!" then return end (8)
local parts = string.Explode(" ", text) (9)
local cmdName = parts[1]:sub(2):lower() -- strip the "!" and lowercase
table.remove(parts, 1) -- remaining parts are arguments
local cmd = COMMANDS[cmdName]
if cmd then
cmd.run(ply, parts)
return "" (10)
else
ply:ChatPrint("[CMD] Unknown command. Type !help")
end
end)
print("[GABRIEL] Command system loaded! Type !help in chat.")
| 1 | A table used as a dictionary — keys are command names, values are command objects. This is how real programs store registrations (routes, CLI subcommands, plugin hooks). |
| 2 | A function that takes parameters. name is a string, fn is a function (functions are values in Lua — you can store them in tables, pass them around). desc is documentation. |
| 3 | ply is the player who typed the command. args is a table of the remaining words. Real CLI tools work the same way: git commit -m "msg" → command=commit, args={"-m", "msg"}. |
| 4 | math.Clamp prevents abuse — can’t spawn 10,000 NPCs. This is input validation, the same concept that prevents SQL injection in web apps. |
| 5 | GetEyeTrace().HitPos — raycasting. Shoots an invisible line from your eyes forward and returns where it hits the world. Used in games, physics engines, and 3D modeling. |
| 6 | Default walk speed is 200, run is 500. We multiply both so the ratio stays consistent. This is proportional scaling — common in UI layout, signal processing, and game balance. |
| 7 | Hooks are GMod’s event system. PlayerSay fires every time someone types in chat. We register a callback function that GMod calls when the event fires. This pattern — register a function to be called later — is foundational: JavaScript event listeners, Python decorators, webhook handlers. |
| 8 | Early return pattern: if the message doesn’t start with !, bail immediately. Keeps the logic flat instead of nesting everything in an if. Senior engineers call this a guard clause. |
| 9 | string.Explode(" ", text) splits "!spawn zombie 5" into {"!spawn", "zombie", "5"}. Same as Python’s str.split() or Bash’s word splitting. |
| 10 | Returning "" suppresses the message from chat — other players don’t see your commands. Returning nil (or nothing) would show it normally. This is message interception. |

Phase 2: NPC Spawner with AI Behaviors
A spawn menu that creates NPCs with custom behaviors — patrol routes, follow the player, attack on sight. Teaches functions with parameters and spatial math.
lua/autorun/server/gabriel_npc_spawner.lua-- GABRIEL'S NPC SPAWNER
-- Spawns NPCs with custom AI behaviors
local function SpawnFollower(ply) (1)
local npc = ents.Create("npc_citizen")
if not IsValid(npc) then return end
npc:SetPos(ply:GetEyeTrace().HitPos + Vector(0, 0, 10))
npc:SetKeyValue("spawnflags", "256") -- long visibility, won't go far
npc:Spawn()
npc:Activate()
-- Make it follow the player
npc:SetSchedule(SCHED_TARGET_CHASE) (2)
npc:SetTarget(ply)
-- Give it a name tag
npc.GabrielName = "Follower #" .. math.random(100, 999)
-- Reacquire target every 3 seconds (3)
timer.Create("follow_" .. npc:EntIndex(), 3, 0, function()
if IsValid(npc) and IsValid(ply) then
npc:SetTarget(ply)
npc:SetSchedule(SCHED_TARGET_CHASE)
else
timer.Remove("follow_" .. npc:EntIndex())
end
end)
ply:ChatPrint("[NPC] " .. npc.GabrielName .. " is now following you!")
return npc
end
local function SpawnPatroller(ply) (4)
local npc = ents.Create("npc_combine_s")
if not IsValid(npc) then return end
local origin = ply:GetEyeTrace().HitPos + Vector(0, 0, 10)
npc:SetPos(origin)
npc:Give("weapon_smg1")
npc:Spawn()
npc:Activate()
npc.GabrielName = "Patrol #" .. math.random(100, 999)
npc.PatrolPoints = {} (5)
-- Generate a square patrol route around spawn point
local radius = 300
local points = {
origin + Vector(radius, 0, 0),
origin + Vector(0, radius, 0),
origin + Vector(-radius, 0, 0),
origin + Vector(0, -radius, 0),
}
local currentPoint = 1
timer.Create("patrol_" .. npc:EntIndex(), 4, 0, function()
if not IsValid(npc) then
timer.Remove("patrol_" .. npc:EntIndex())
return
end
npc:SetLastPosition(points[currentPoint]) (6)
npc:SetSchedule(SCHED_FORCED_GO_RUN)
currentPoint = currentPoint % #points + 1 (7)
end)
ply:ChatPrint("[NPC] " .. npc.GabrielName .. " patrolling (radius " .. radius .. ")")
return npc
end
-- Wire into the command system if it exists
hook.Add("PlayerSay", "GabrielNPCSpawner", function(ply, text)
if text == "!follow" then
SpawnFollower(ply)
return ""
elseif text == "!patrol" then
SpawnPatroller(ply)
return ""
end
end)
print("[GABRIEL] NPC Spawner loaded! Commands: !follow, !patrol")
| 1 | Functions that return something — SpawnFollower creates an NPC and returns it. The caller can use the return value to do more with it. This is how APIs work: you call a function, it does work, it gives you back a result. |
| 2 | Schedules are GMod’s AI behavior system. SCHED_TARGET_CHASE means "move toward your target." The NPC doesn’t know how to navigate — the engine’s pathfinding handles that. You just declare what you want. This is declarative programming. |
| 3 | timer.Create runs a function repeatedly (every 3 seconds, forever — 0 means infinite repeats). The function inside checks if the NPC and player still exist (IsValid) before acting. This is defensive programming — never assume something still exists. Real servers do the same: check if a database connection is alive before querying. |
| 4 | Same pattern, different behavior. Both functions create NPCs but configure them differently. This is polymorphism at its simplest — same interface, different behavior. |
| 5 | Empty table assigned to the NPC as a custom field. Lua lets you add any field to any table at runtime. This is both powerful and dangerous — no compiler catches typos. |
| 6 | SetLastPosition + SCHED_FORCED_GO_RUN = "run to this exact point." We cycle through 4 corners of a square. The NPC walks a patrol route. |
| 7 | Modular arithmetic for cycling: 1 → 2 → 3 → 4 → 1 → 2 → …. The % operator wraps around. This pattern appears everywhere: circular buffers, round-robin schedulers, clock arithmetic. |

Quick Commands
Git & GitHub CLI
gh repo create <name> --private --source . --remote origin --push
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

git log --oneline -- $(find . -name "*.adoc" -type f -newermt "$(date +%F)")
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
gh repo list --limit 100 --json name,description \
| jq -r '.[] | select(.name | test("domus|antora|asciidoc"; "i")) | "\(.name)\t\(.description)"'
gh repo list --limit 100 --json name,description,updatedAt \

gh repo list --limit 100 --json name,diskUsage \
| jq -r '.[] | "\(.diskUsage)\t\(.name)"' | sort -rn | head -10
gh repo clone EvanusModestus/<repo-name> ~/atelier/_bibliotheca/<repo-name>
find & grep
find . -name "*.adoc" -type f -newermt "$(date +%F)" | sort
-mtime 0 means "last 24 hours", not "today". -newermt "$(date +%F)" compares against midnight — exact.
|
find . -iname "*mschap*" -type f | sort
find . -type f \( -iname "*ise*" -o -iname "*mschap*" \) | sort
find . -type f -iregex '.*\(ise\|mschap\).*'
find . -type f -iname "*meeting*" \

-not -path "*/.git/*" \
-not -path "*/build/*"
find .drafts -type f -printf '%T@ %Tc %p\n' | sort -rn | awk '{$1="";print}' | head -3
grep -rl "pattern" . --include="*.adoc" # file count (which files)
grep -rn "pattern" . --include="*.adoc" # line matches (every occurrence)
grep -rc "pattern" . --include="*.adoc" | grep -v ':0$' # match count per file
grep -rn -E 'git init|gh repo create' docs/ --include='*.adoc' -B2 -A2
Search codex by content — which files contain a command?
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.
find docs/modules/ROOT -name "powershell" -type d \
-exec sh -c 'echo "$1: $(find "$1" -type f | wc -l) files"' _ {} \;
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
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.
nvim $(find docs/modules/ROOT -name '*.adoc' -type f \
-exec grep -l 'token.*expire\|oauth.*refresh' {} \;)
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
grep -rl 'commands/shell' docs/modules/ROOT/partials/
grep -rl 'quick-commands' docs/modules/ROOT | wc -l
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
find docs/modules/ROOT -name "*urgent.adoc*" -type f
find docs/modules/ROOT -name "*morning.adoc*" -type f
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.
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.
grep -rn --include='*.adoc' -c 'sanchuelo' . | grep -v ':0$'
grep -rl --include='*.adoc' -i 'sanchuelo' ~/atelier/_bibliotheca/ | sort
grep -rn --include='*.adoc' -i -B1 -A1 'sanchuelo' ~/atelier/_bibliotheca/domus-captures/
grep -rl -i 'sanchuelo' ~/atelier/_bibliotheca/ --include='*.txt' --include='*.adoc' | sort
find ~/atelier/_bibliotheca/ -type f \( -name '*.adoc' -o -name '*.txt' \) -print0 \
| xargs -0 grep -li 'sanchuelo' | sort
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
# Find files — filenames only
grep -rl 'build-antora-page' docs/modules/ROOT/partials/worklog/
# 3 lines of context around each hit
grep -rn -C3 'build-antora-page' docs/modules/ROOT/partials/worklog/
grep -rPn 'theme\s+(light-cyan|catppuccin|mocha)' docs/modules/ROOT/partials/
find docs/modules/ROOT/partials/worklog/daily-notes -name '*.adoc' \
-exec grep -l 'build-antora-page\|build-adoc\|--theme\|pdf' {} \;
find docs/modules/ROOT/partials/worklog/daily-notes -name '*.adoc' \
-exec awk '/build-antora-page|build-adoc|--theme/{print FILENAME": "$0}' {} \;
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.
find docs/modules/ROOT/partials/worklog -name '*.adoc' -exec \
sed -n '/\[source,bash\]/,/^----$/{/build-antora-page/p}' {} +
grep -rn 'build-antora-page\|build-adoc' data/ --include='*.adoc'
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
grep -P '(@\w+|^From:.*<)' comms.adoc
grep -nP '\d{1,2}/\d{1,2}/\d{2,4}|20\d{2}-\d{2}-\d{2}' comms.adoc
grep -niP '(I can |I will |I.ll |we will |we.ll )' comms.adoc
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.
|
# 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.
# 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-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.
# 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.
# 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.
# 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 " $0} END {for (s in seen) if (seen[s]>1) print files[s]}'
# md5sum only files with duplicate sizes (two-pass: fast then precise)
find ~/Downloads -type f -printf '%s\n' | sort | uniq -d | while read -r size; do
find ~/Downloads -type f -size "${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.
# 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.
# 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.
# 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
# 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/$base"
done
IFS= read -r -d '' — the holy trinity for null-safe filename reading. IFS= prevents whitespace trimming. -r prevents backslash interpretation. -d '' reads until null.
# Sort Downloads chaos into folders by type
find ~/Downloads -maxdepth 1 -type f -print0 | while IFS= read -r -d '' f; do
ext="${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
${f##.} — parameter expansion: strip longest match of . from front, leaving only the extension. No basename or awk needed.
# Convert all epubs in a directory to asciidoc via pandoc
find . -name '*.epub' -type f -exec sh -c '
for epub; do
adoc="${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
# 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.
# 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.
# 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
# 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.
# 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
awk '{print $2}' file.txt
awk -F: '{print $1, $3}' /etc/passwd
awk '/\[source,json\]/{getline; if ($0 ~ /^----/) {p=1; next}} p && /^----/{p=0; next} p' file.adoc
awk '{printf "%-30s %s\n", $1, $2}' file.txt
sed — stream editing
# 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
sed -n '10,20p' file.txt
sed — line-targeted replacement (verify-before / change / verify-after)
# 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.
awk 'NR==1218 || NR==1760' zsh/.zshrc
# 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
# 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.
# 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
curl -s localhost:8080/stats | jq '.stats.total_files'

Shell Patterns
xargs — when the next command reads arguments, not stdin
| Next command reads… | Use |
|---|---|
stdin ( |
pipe directly |
arguments ( |
|
-I{} placeholdermkdir -p /tmp/adoc-backup-$(date +%F) && \
find . -name "*.adoc" -type f -newermt "$(date +%F)" | \
xargs -I{} cp {} /tmp/adoc-backup-$(date +%F)/
-P4 runs 4 at a timefind .drafts -name "*.adoc" -type f | xargs -P4 -I{} asciidoctor -o /dev/null {}
find . -name "*.adoc" -type f -print0 | xargs -0 wc -l
Process substitution — <(cmd) treats output as a file
diff <(grep '|' partials/trackers/work/adhoc/carryover.adoc | head -20) \
<(git show HEAD~1:partials/trackers/work/adhoc/carryover.adoc | grep '|' | head -20)
diff <(find docs/modules/ROOT/pages/projects/chla/mschapv2-migration -name "*.adoc" -type f | sort) \
<(grep -oP 'mschapv2-migration/[^[]+\.adoc' docs/modules/ROOT/nav.adoc | sort)
Command substitution — embed output as arguments
nvim "$(find data/ -name '*.adoc' -type f -printf '%T@ %p\n' | sort -rn | awk 'NR==1{print $2}')"
wc -l $(find docs/modules/ROOT -path '*mschapv2*' -name '*.adoc' -type f)
Conditional execution — capture, test, act
files=$(find .drafts -name 'in*' -type f) && [ -n "$files" ] && nvim $files
files=$(grep -rl '\[ \]' .drafts/*.adoc) && [ -n "$files" ] && nvim $files
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
--- as invalid optionprintf '---\n\n'
--- as dataprintf '%s\n\n' '---'
Kill stuck SSH sessions
lsof -i TCP -n -P | awk '/ssh.*ESTABLISHED/ {print $2, $9}'
lsof -i TCP -n -P | awk '/ssh.*kvm-01.*ESTABLISHED/ {print $2}' | sort -u | xargs kill
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.

Security & Encryption
View encrypted files without writing to disk
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
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
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
