It's not env but the older jq that doesn't take -Mf option. I will modify the README so it works for older jq.

I'm using jq-1.6 . macOS is BSD-based, shebang supports multiple options. However, Linux does not support it.

ah. you are right. env -S would do if your Linux uses GNU coreutils v8.30 or newer.

Fixed the readme and the script.
