### Bash Scripting Basic Hygiene Checklist

| Task             | Recommendation          | Why?                                                                 |
| :--------------- | :---------------------- | :------------------------------------------------------------------- |
| **The Shebang** | `#!/usr/bin/env bash`   | Maximum portability across different Unix-like systems.              |
| **Error Handling** | `set -euo pipefail`     | Ensures the script stops at the first sign of trouble.              |
| **Quoting** | **`"$VARIABLE"`** | Prevents word splitting and globbing (essential for paths).          |
| **Variable Style** | `local_var="value"`     | Lowercase prevents overwriting system-wide environment variables.    |
| **Boilerplate** | `readonly CONSTANT`     | Prevents accidental modification of fixed values.                    |
| **Extensions** | `.sh` or none           | Helps with syntax highlighting and identifying file types.           |
| **Permissions** | `chmod +x`           | Use this tool to change permissions to make the script executable.           |
