In such questions it's important to show your shebang since
that's what runs your script.
Given your symptoms I guess you're using the following:
#!/bin/env rdmd
And indeed rdmd won't call your script if it doesn't have the
proper extension.
Try using this instead:
#!/bin/dmd -run
The shebang I used: #!/usr/bin/env rdmd
I was visiting Dlang Tour and that's where I've got an example
of shebang usage, directly from there:
https://tour.dlang.org/tour/en/welcome/run-d-program-locally#/on-the-fly-compilation-with-rdmd
The shebang you suggested actually works perfectly:
#!/bin/dmd -run
"And indeed rdmd won't call your script if it doesn't have the
proper extension."
Then why does Dlang Tour includes shebang: #!/usr/bin/env rdmd
Instead of the one you mentioned, that is fool proof.
(#!/bin/dmd -run)
Is that an error/mistake in Dlang Tour guide?
Well, because it isn't fool proof either ;-)
It won't work once you start using more files as you would then
need the -i flag , but unfortunately most systems don't support
more than one shebang argument.
I think it's simply a missing feature of rdmd to accept files
without an extension as D programs (though of course the tour
could be improved to be more explanatory here too).
