Hm... right off I see the shebang is not the first line in the example. It has to be.

Nice writeup!

Very nice! Clearly I'm not taking enough advantage of scripting capabilities!

Thanks for your work, nice article, I wasn't even aware how easy this is.

FYI, the code will compile faster if you use `dmd -run` instead of `rdmd`. If you have multiple files that need to be compiled you can use `dmd -i -run`.

Unfortunately, you can't pass more than one command-line argument on a #! line.

Please fix, Aberba, right now the examples don't work because of this...

Yes, noted. I don't have direct access to edit it myself. I have to wait till the editors make the changes (depending on their TZ)

I should really get someone here to proofread it next time 😅 Sorry about that.

It is possible, using `/usr/bin/env -S command arg1 arg2` , as of coreutils 8.30. I have been using it at work and it's working perfectly. This functionality was already supported by FreeBSD [1] for ~15 years, but the coreutils developers implemented it just ~3 years ago [2].

The main disadvantage is that it's obviously not very portable, e.g. all users/developers need to use a modern linux distro, but for some teams this requirement already there for other reasons, so it's not a problem.

Example: https://gist.github.com/PetarKirov/72168d8dc909c670444ca649ec28f80f
This was extracted from a larger project, so it may not be useful on its own, but hopefully it should be enough to showcase the usage.
Also, if you can use rund [3], it's likely a much cleaner option.
