fb7a2ecf9298edca09ec610c261fbf353013881fnd checks the syntax and integrity of a zone file. It performs the
fb7a2ecf9298edca09ec610c261fbf353013881fnd same checks as <span><strong class="command">named</strong></span> does when loading a
fb7a2ecf9298edca09ec610c261fbf353013881fnd zone. This makes <span><strong class="command">named-checkzone</strong></span> useful for
fb7a2ecf9298edca09ec610c261fbf353013881fnd checking zone files before configuring them into a name server.
fb7a2ecf9298edca09ec610c261fbf353013881fnd <span><strong class="command">named-compilezone</strong></span> is similar to
fb7a2ecf9298edca09ec610c261fbf353013881fnd <span><strong class="command">named-checkzone</strong></span>, but it always dumps the
fb7a2ecf9298edca09ec610c261fbf353013881fnd zone contents to a specified file in a specified format.
fb7a2ecf9298edca09ec610c261fbf353013881fnd Additionally, it applies stricter check levels by default,
fb7a2ecf9298edca09ec610c261fbf353013881fnd since the dump output will be used as an actual zone file
fb7a2ecf9298edca09ec610c261fbf353013881fnd loaded by <span><strong class="command">named</strong></span>.
fb7a2ecf9298edca09ec610c261fbf353013881fnd When manaully specified otherwise, the check levels must at
fb7a2ecf9298edca09ec610c261fbf353013881fnd least be as strict as those specified in the
fb7a2ecf9298edca09ec610c261fbf353013881fnd <span><strong class="command">named</strong></span> configuration file.
fb7a2ecf9298edca09ec610c261fbf353013881fnd Enable debugging.

fb7a2ecf9298edca09ec610c261fbf353013881fnd program and exit.
fb7a2ecf9298edca09ec610c261fbf353013881fnd When loading the zone file read the journal if it exists.
