NAME

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

SYNOPSIS

       ldns-compare-zones [-c] [-i] [-d] [-z] 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.

       -h     Show usage and exit

       -v     Show the version and exit
