journalprint — print zone journal in human-readable form
journalprint {journal}
journalprint prints the contents of a zone journal file in a human-readable form.
Journal files are automatically created by named
when changes are made to dynamic zones (e.g., by
nsupdate). They record each addition
or deletion of a resource record, in binary format, allowing the
changes to be re-applied to the zone when the server is
restarted after a shutdown or crash. By default, the name of
the journal file is formed by appending the extension
.jnl to the name of the corresponding
zone file.
journalprint converts the contents of a given journal file into a human-readable text format. Each line begins with "add" or "del", to indicate whether the record was added or deleted, and continues with the resource record in master-file format.
