I am trying to do a clean daily move of large archive files over the network.
I want the archived files to be cleanly removed once copied and my script
replaces the moved directories with a symlink to the new location.

That sort of thing just adds complication & a sense of when this happened
is lost because of the delays imposed by the pipe (I have had some 'mv's
run for several hours moving log files to archive on a not-very-fast san).
Also: the exit code that the shell sees is of 'grep', not 'mv'.
I go to lengths to detect errors - which is why I am trying to preserve
'meaningful' errors (and loose irrelevant ones).
