.SH SYNOPSIS
.sp
\fBnamed\-journalprint\fP [\fB\-dux\fP] {journal}
.SH DESCRIPTION
.sp
\fBnamed\-journalprint\fP 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.
.sp
Journal files are automatically created by \fBnamed\fP when changes are
made to dynamic zones (e.g., by \fBnsupdate\fP). 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 \fB\&.jnl\fP to the name of the corresponding zone
file.
.sp
\fBnamed\-journalprint\fP converts the contents of a given journal file
into a human\-readable text format. Each line begins with \fBadd\fP or \fBdel\fP,
to indicate whether the record was added or deleted, and continues with
the resource record in master\-file format.
.sp
The \fB\-x\fP option causes additional data about the journal file to be
printed at the beginning of the output and before each group of changes.
.sp
The \fB\-u\fP (upgrade) and \fB\-d\fP (downgrade) options recreate the journal
file with a modified format version.  The existing journal file is
replaced.  \fB\-d\fP writes out the journal in the format used by
versions of BIND up to 9.16.11; \fB\-u\fP 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 \fImust not\fP be used while
\fBnamed\fP is running.
