Do you care what the value *was*? If not, find the line, and replace the entire line, simply setting the serial number to a new value. e.g. year+month+day+hour+minute+second DNS serial numbers merely have to be greater than the prior value to be paid attention to. If you use that technique, it's virtually guaranteed. NB: if more than one thing changes serial numbers using this method, pay attention to timezones (for the generated numbers) and get everything to generate GMT/UTC derived ones. -- [tim@localhost ~]$ uname -rsvp Linux 4.16.11-100.fc26.x86_64 #1 SMP Tue May 22 20:02:12 UTC 2018 x86_64 Boilerplate: All mail to my mailbox is automatically deleted.
