dns_incrementor
I got really sick of incrementing the DNS serial. So I made this.
It replaces your zone serial in YYYYmmddxx (xx being the version for the day) with the latest date and resets the version counter if necessary
Installation
gem install dns_incrementor
Usage
dns_incrementor example.zone
Bugs
It will overflow the serial if you make more than 100 revisions in a day (eg. 2014123199 -> 20141231100). If you need to make more than 100 revisions a day, then either you're doing something very wrong or you've got enough going on that maybe this script isn't for you.
