NAMED-JOURNALPRINT(1) BIND 9 NAMED-JOURNALPRINT(1) NAME named-journalprint - print zone journal in human-readable form SYNOPSIS named-journalprint [-c serial] [-dux] {journal} DESCRIPTION named-journalprint scans the contents of a zone journal file, printing it in a human-readable form, or, optionally, converting it to a differ- ent journal file format. 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 shut- down 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. named-journalprint converts the contents of a given journal file into a human-readable text format. Each line begins with add or del, to indi- cate whether the record was added or deleted, and continues with the resource record in master-file format. The -c (compact) option provides a mechanism to reduce the size of a journal by removing (most/all) transactions prior to the specified ser- ial number. Note: this option must not be used while named is running, and can cause data loss if the zone file has not been updated to con- tain the data being removed from the journal. Use with extreme caution. The -x option causes additional data about the journal file to be printed at the beginning of the output and before each group of changes. The -u (upgrade) and -d (downgrade) options recreate the journal file with a modified format version. The existing journal file is replaced. -d writes out the journal in the format used by versions of BIND up to 9.16.11; -u writes it out in the format used by versions since 9.16.13. (9.16.12 is omitted due to a journal-formatting bug in that release.) Note that these options must not be used while named is running.
