(I no longer remember the specifics of the tasks involved, so I can't explain why this was what I needed.) The only way I can/could think of to do that with an argument to '-exec' involved putting the pipeline sequence into a script and calling that via -exec, but that's more unwieldy than I want to work with in most cases. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
