I guess adding =E2=80=9Cand tag:new=E2=80=9D won't hurt.

(You've mised FolderX in the cp command).

What's wrong with

	notmuch search --output=3Dfiles ... |
		xargs --no-run-if-empty \
		cp -t "$MAILDIR/notmuch/FolderX/cur/" --

expect that --no-run-if-empty is not POSIX and I'm not sure about -t.

I'm also wondering if it would make sense to link the files instead of
copying:

	notmuch search --output=3Dfiles ... |
		xargs --no-run-if-empty \
		ln -t "$MAILDIR/notmuch/FolderX/cur/" --

--=20
