named-journalprint — print zone journal in human-readable form
named-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
named-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.
