NAME
       ldns-compare-zones - read and compare two zonefiles and print differences

SYNOPSIS
       ldns-compare-zones [-c] [-i] [-d] [-z] [-s] ZONEFILE1 ZONEFILE2

DESCRIPTION
       ldns-compare-zones reads two DNS zone files and prints number of differences.
       Output is formated to:
               +NUM_INS        -NUM_DEL        ~NUM_CHG

       The  major  comparison  is based on the owner name. If an owner name is present in zonefile 1, but not in zonefile 2, the
       resource records with this owner name are considered deleted, and counted as NUM_DEL. If an  owner  name  is  present  in
       zonefile  2,  but  not  in  zonefile 1, the resource records with this owner name are considered inserted, and counted as
       NUM_INS. If an owner name is present in both, but there is a difference in the amount or content of  the  records,  these
       are considered changed, and counted as NUM_CHG.

OPTIONS
       -c     Print  resource  records  whose  owner  names are in both zone files, but with different resource records. (a.k.a.
              changed)

       -i     Print resource records whose owner names are present only in ZONEFILE2 (a.k.a. inserted)

       -d     Print resource records whose owner names are present only in ZONEFILE1 (a.k.a. deleted)

       -a     Print all changes. Specifying this option is the same as specifying -c -i amd -d.

       -z     Suppress zone sorting; this option is not recommended; it can cause records to be incorrectly marked  as  changed,
              depending of the nature of the changes.

       -s     Do not exclude the SOA record from the comparison.  The SOA record may then show up as changed due to a new serial
              number.  Off by default since you may be interested to know if (other zone apex elements) have changed.

       -h     Show usage and exit

       -v     Show the version and exit
