.SH NAME
debconf\-copydb \- copy a debconf database
.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 1
\& debconf\-copydb sourcedb destdb [\-\-pattern=pattern] [\-\-owner\-pattern=pattern] [\-\-config=Foo:bar]
.Ve
.SH DESCRIPTION
.IX Header "DESCRIPTION"
\&\fBdebconf-copydb\fR copies items from an existing debconf database into
another, possibly new database. The two databases may have different
formats; if so a conversion will automatically be done.
.SH OPTIONS
.IX Header "OPTIONS"
.IP \fIsourcedb\fR 4
.IX Item "sourcedb"
The name of the source database. Typically it will be defined
in your debconf.conf (or .debconfrc) file.
.IP \fIdestdb\fR 4
.IX Item "destdb"
The name of the destination database. It may be defined in
debconf.conf or .debconfrc, or you might define it on the command line (see
below).
.IP "\fB\-p\fR \fIpattern\fR, \fB\-\-pattern\fR \fIpattern\fR" 4
.IX Item "-p pattern, --pattern pattern"
If this is specified, only items in \fIsourcedb\fR whose names match the pattern
will be copied.
.IP "\fB\-\-owner\-pattern\fR \fIpattern\fR" 4
.IX Item "--owner-pattern pattern"
If this is specified, only items in \fIsourcedb\fR whose owners match the pattern
will be copied.
.IP "\fB\-c\fR \fIfoo:bar\fR, \fB\-\-config\fR \fIFoo:bar\fR" 4
.IX Item "-c foo:bar, --config Foo:bar"
Set option Foo to bar. This is similar to writing:
.Sp
.Vb 1
\&  Foo: bar
.Ve
.Sp
In debconf.conf, except you probably want to leave off the space on the
command line (or quote it: "Foo: bar"). Generally must be used multiple
times, to build up a full configuration stanza. While blank lines are used
to separate stanzas in debconf.conf, this program will assume that
"Name:dbname" denotes the beginning of a new stanza.
.SH EXAMPLES
.IX Header "EXAMPLES"
.Vb 1
\&  debconf\-copydb configdb backup
.Ve
.PP
Copy all of configdb to backup, assuming you already have the backup
database defined in debconf.conf.
.PP
.Vb 3
\&  debconf\-copydb configdb newdb \-\-pattern=\*(Aq^slrn/\*(Aq \e
\&        \-\-config=Name:newdb \-\-config=Driver:File \e
\&        \-\-config=Filename:newdb.dat
.Ve
.PP
Copy slrn's data out of configdb, and into newdb. newdb is not defined in
the rc file, so the \-\-config switches set up the database on the fly.
.PP
.Vb 2
\&  debconf\-copydb configdb stdout \-c Name:stdout \-c Driver:Pipe \e
\&        \-c InFd:none \-\-pattern=\*(Aq^foo/\*(Aq
.Ve
.PP
Spit out all the items in the debconf database related to package foo.
.PP
.Vb 4
\&  debconf\-copydb configdb pipe \-\-config=Name:pipe \e
\&                \-\-config=Driver:Pipe \-\-config=InFd:none | \e
\&        ssh remotehost debconf\-copydb pipe configdb \e
\&                \-\-config=Name:pipe \-\-config=Driver:Pipe
.Ve
.PP
This uses the special purpose pipe driver to copy a database to a remote
system.
