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
