me too but i typed "file --help" in my terminal before i wrote the reply

the good with this sort of attitude is that i help people to help
them self, not only for the current problem, now he has a chance
in case of a completly different CLI tool to remember "hey sometime
ago there was --help after the command i try to use"

the default approach for nearly all CLI tools is to support
"binary --help" or "binary -h", frankly ffmpeg does the same

the same as i did before i wrote my reply, just type "file --help"
and then i searched a folder with a lot of different media files
typed the command and posted the output
