In this very generic example && not work to finalize the instruct and start a new instruct. Yes, I know dmd can build and run without it, but this is only a example.

execute(["cmd", "/c", "dmd test.d", "&&", "start test.exe"]);

How can I substitute && ?

`&&` is a feature of the shell, so you need to use `executeShell`.

You can use executeShell() as mentioned already or do something like this:

auto p = execute(["dmd", "test.d"]);
if(p.status == 0) {
   execute(["test.exe"]);
}

Try other variants:

execute(["cmd", "/c", "dmd test.d && start test.exe"]);
execute(["cmd", "/c", "dmd", "test.d", "&&", "start", "test.exe"]);
