### 17. Writing Files Without Heredocs
```bash
# ❌ WRONG - echo / printf / tee
echo "# Config" > /opt/app/config.yml
echo "port: 3000" >> /opt/app/config.yml
printf "# Config\nport: 3000\n" > /opt/app/config.yml
cat config.yml | tee /opt/app/config.yml
```
```bash
# ✅ CORRECT - always use a single heredoc
cat <<EOF >/opt/app/config.yml
# Config
port: 3000
EOF
```
