NAMED-JOURNALPRINT(8)               BIND 9               NAMED-JOURNALPRINT(8)



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
       different 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
       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.

       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.

       The -c (compact) option provides a mechanism to reduce the size of a
       journal by removing (most/all) transactions prior to the specified
       serial 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 contain 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.
