Avoid OS-specific commands or paths. Use Python for scripts instead of platform-specific shell scripts. ## Python ALWAYS run Python scripts with the `python` CLI (not `python3`). ## Shell Safety When executing shell commands, ALWAYS quote arguments that may contain special characters (e.g., URLs with `?`, `&`, whitespace) to prevent shell parsing errors. --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/alexandreroman) — claim your Tome and manage your conversions.
