Section: Debconf (1)
debconf [options] command [args]
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.
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
