debconf - run a debconf-using program


debconf [options] command [args]


Debconf is a configuration system for Debian packages. For a debconf overview and
documentation for sysadmins, see debconf(7) (in the debconf-doc package).

The debconf program runs a program under debconf's control, setting it up to talk with
debconf on stdio. The program's output is expected to be debconf protocol commands, and it
is expected to read result codes on stdin. See debconf-devel(7) for details about the
debconf protocol.

The command to be run under debconf must be specified in a way that will let your PATH
find it.

This command is not the usual way that debconf is used. It's more typical for debconf to
be used via dpkg-preconfigure(8) or dpkg-reconfigure(8).


-opackage, --owner=package
Tell debconf what package the command it is running is a part of. This is necessary to
get ownership of registered questions right, and to support unregister and purge
commands properly.

-ftype, --frontend=type
Select the frontend to use.

-pvalue, --priority=value
Specify the minimum priority of question that will be displayed.

Enables terse output mode. This affects only some frontends.


To debug a shell script that uses debconf, you might use:

DEBCONF_DEBUG=developer debconf my-shell-prog

Or, you might use this:

debconf --frontend=readline sh -x my-shell-prog

Use debconf online using onworks.net services
