For those who have needed to make a bunch of DNS changes and want to verify what the effect of those changes are, here is a little shell script that does a sort of regression test. Basically, it tells you what changes were made to a zone so you can see if any major mistakes were made.
The usage is simple try dnscheck -? for a list of options. It isn’t the fanciest thing in the world, but for those who need it, it might be helpful.
Open it in your favorite text editor to set the basic configuration options and make it executable and you are on your way.
