DEBCONF-COMMUNICATE(1) Debconf DEBCONF-COMMUNICATE(1)NAME
debconf-communicate - communicate with debconf
echo commands | debconf-communicate [options] [package]
debconf-communicate allows you to communicate with debconf on the fly, from the command line. The package argument is the name of the
package which you are pretending to be as you communicate with debconf, and it may be omitted if you are lazy. It reads commands in the
form used by the debconf protocol from stdin. For documentation on the available commands and their usage, see the debconf specification.
The commands are executed in sequence. The textual return code of each is printed out to standard output.
The return value of this program is the numeric return code of the last executed command.
echo get debconf/frontend | debconf-communicate
Print out the value of the debconf/frontend question.
This program should never be used from a maintainer script of a package that uses debconf! It may however, be useful in debugging.

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
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
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.
Select the frontend to use.
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
