LEARN ABOUT DEBIAN
debconf
DEBCONF(1) Debconf DEBCONF(1)
NAME
debconf - run a debconf-using program
SYNOPSIS
debconf [options] command [args]
DESCRIPTION
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).
OPTIONS
-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.
--terse
Enables terse output mode. This affects only some frontends.
EXAMPLES
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
