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.

       -e     Exit with status code 2 when zones differ.

       -h     Show usage and exit

       -v     Show the version and exit
