DEBCONF-COPYDB(1) Debconf DEBCONF-COPYDB(1)

NAME
debconf-copydb - copy a debconf database

SYNOPSIS
debconf-copydb sourcedb destdb [--pattern=pattern] [--owner-pattern=pattern] [--config=Foo:bar]

DESCRIPTION
debconf-copydb 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.

OPTIONS
sourcedb
The name of the source database. Typically it will be defined in
your debconf.conf (or .debconfrc) file.

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).

-p pattern, --pattern pattern
If this is specified, only items in sourcedb whose names match the
pattern will be copied.

--owner-pattern pattern
If this is specified, only items in sourcedb whose owners match the
pattern will be copied.

-c foo:bar, --config Foo:bar
Set option Foo to bar. This is similar to writing:

Foo: bar

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.

EXAMPLES
debconf-copydb configdb backup

Copy all of configdb to backup, assuming you already have the backup
database defined in debconf.conf.

debconf-copydb configdb newdb --pattern='^slrn/' \
--config=Name:newdb --config=Driver:File \
--config=Filename:newdb.dat

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.

debconf-copydb configdb stdout -c Name:stdout -c Driver:Pipe \
-c InFd:none --pattern='^foo/'

Spit out all the items in the debconf database related to package foo.

debconf-copydb configdb pipe --config=Name:pipe \
--config=Driver:Pipe --config=InFd:none | \
ssh remotehost debconf-copydb pipe configdb \
--config=Name:pipe --config=Driver:Pipe

This uses the special purpose pipe driver to copy a database to a
remote system.
