Thanks for all the answers. I've modified my script. Works great.
Perderabo: i tought about rcs but its an automated process from our vmware team so maybe i'll try to pitch the idea to them but seeing about 100 backup copies of the files (no backup dir, no cleanups, etc) i think its safe to say they are asking for trouble. I'm only here for a project not related and the asked me if i could write a script for them. Its internal DNS for testing network so doesn't go on the net

dnsextd(8) BSD System Manager's Manual dnsextd(8) NAME
dnsextd -- BIND Extension Daemon SYNOPSIS
dnsextd DESCRIPTION
dnsextd is a daemon invoked at boot time, running alongside BIND 9, to implement two EDNS0 extensions to the standard DNS protocol. dnsextd allows clients to perform DNS Updates with an attached lease lifetime, so that if the client crashes or is disconnected from the net- work, its address records will be automatically deleted after the lease expires. dnsextd allows clients to perform long-lived queries. Instead of rapidly polling the server to discover when information changes, long-lived queries enable a client to indicate its interest in some set of data, and then be notified asynchronously by the server whenever any of that data changes. dnsextd has no user-specifiable command-line argument, and users should not run dnsextd manually. SEE ALSO
mDNS(1) mDNSResponder(8) For information on Dynamic DNS Update, see RFC 2136 "Dynamic Updates in the Domain Name System (DNS UPDATE)" For information on Dynamic DNS Update Leases, see http://files.dns-sd.org/draft-dns-update-leases.txt For information on Long-Lived Queries, see http://files.dns-sd.org/draft-dns-llq.txt BUGS
dnsextd bugs are tracked in Apple Radar component "mDNSResponder". HISTORY
The dnsextd daemon first appeared in Mac OS X 10.4 (Tiger). Darwin June 2, 2019 Darwin
