When you ran pause, did it print the text "press any key to
continue"?
You are absolutely correct.
There was no output, it was captured, as executeShell is used for
capturing command output.
auto commandOutput = executeShell("pause");
writeln("Here is the output: ", commandOutput);
// Here is the output: Tuple!(int, "status", string,
"output")(0, "Press any key to continue . . . \r\n")
executeShell captures the output of the program, so I'm
guessing no. And that is why cls does nothing - its output is
captured into a string instead of displayed on screen.
spawnShell keeps the output connected unless you ask it not to.

Thanks for summarising.
