copy /y x y >> nul:

will copy x to y and not tell me that it's done so, nor will it ask me
to confirm that y should be copied over if it already exists. Good,
that (so far as it goes) is what I want.

Unfortunately if x doesn't exist I won't see the message "The system
cannot find the file specified.". I could test errorlevel if my copy
command was in a batch file, but I'd like it to be one command on the
command line. So my question is this:

Is there a switch to copy that means "Keep quite unless the source
doesn't exist."?

There is no switch that means "keep Quiet" at all, which is why you
redirect the output to nul:

It ought to be possible to redirect standard output and error output
independently of one another, you can with Unix.

If the output is important, leave it visible.

Xcopy may be of more use, particularly the \Q option

Trouble is

xcopy file-that-exists file-that-doesn't-exist

wants to know if file-that-doesn't-exist is a directory or not.

You do know that /? after any standard command lists its options?

Yes.

Thanks.
