On http://www.d-programming-language.org/rdmd.html Andrei states:

(Under Windows replace cat with type and #!/usr/bin/rdmd with #!rdmd, the latter assuming that rdmd can be found in your path.)

what is the #!rdmd about ? I know of no windows shebang syntax, and trying it it a batch file, and in a .d file yielded no results.

rdmd is in the path. Win 7. ran .bat and .d files both from windows shell and a cmd prompt.

dont really need it, but I know Andrei is usually pretty precise about these kind of things - and it peaked my curiosity. maybe in MSDOS it worked ?

No, MS-DOS used extensions like Windows.

Shebang makes sense if you try to run a D program from a bash-like shell, e.g. using MSys or CygWin. It'd make sense to look for rdmd in the PATH (as opposed to passing an absolute path), assuming that'll work at all. Replacing cat with type seems odd, though, since using a shebang-aware shell implies that other Unix-like tools are available, like cat.

You may want to repost this to digitalmars.D. This newsgroup is deprecated, and few people follow it.

thanks for your response.

I assumed he meant natively not using a 'nix shell.

will repost as you suggested to digitalmars.D
