No problem:)

Create a file sample.d with following content

#!/usr/bin/env dub
/+ dub.sdl:
   name "sample"
   versions "test"
+/
void main() {
	import std.stdio : writeln;
	writeln("Hello, World!");
}

You can start it with "dub sample" or if you add the executable 
flag with "./sample.d".

With recent dub version you can name the file even without the .d 
extension and just start it with "./sample".

Kind regards
