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
}
