Steps to reproduce

Run:
nodemon --help >/dev/null

########
I was trying to use this command to check for existence of nodemon, and install if necessary.
I guess I will instead use type nodemon >/dev/null 2>&1 || npm install -g nodemon.
But it's a bit naff that nodemon crashes in this usage.

Well, personally, I reckon this should be fixed.

[remy]

@peternann I agree that if you feel personally about an issue, it should definitely be fixed. Happy to merge your PR (it will need at least a single test to show the issue too).

Cheers 👍
