I'm trying to run this command:

wget -O - URL | gpg -d and get the result of the action, but I can't quite work out to do it.

currently it looks like:

executeShell(escapeShellCommand("wget", "-O", "-", url, "|", "gpg", "-D"));

But I can't work out how to pull the string returned with this.

Any help?

executeShell returns the status and the output as a type (perhaps a tuple? :) ):

  http://dlang.org/phobos/std_process.html#.executeShell

You use the return value for both the status and the output:

    auto wget = executeShell(escapeShellCommand(/* ... */));

    if (wget.status == 0) {
        /* success */
        writeln(wget.output);    // <-- HERE
    }

Certainly not. The output is an object of a special type, which the documentation refers to as 'auto'. Grrr... :) Ok, maybe it's a Voldemort type. Anyway...

That's idiotic, to be frank, it should just be a traditional struct declared outside.

The function's documentation has a "Returns" section, which says:
