I'm not sure what gave you the impression anyone was trying to use the
clipboard as a buffer for a batch process.  I can't see anyone using
batch at all, for that matter.  (Or do you mean "shell" instead of
"batch"?  The two are different things.)

My original use case (as mentioned in my original email) was a `find`
command that `-exec`'d multiple times to produce output.  That went to
the clipboard, for me to paste into a Windows application.

The shell code I posted was a simple test case to show the problem, not
actually what I'm trying to achieve.  Posting simplified example code
that demonstrates a problem is a common way to get help because it means
others only need to understand the simple example, not the full problem:
