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 SEE ALSO

DEBCONF-SET-SELECTIONS(1)					      Debconf						 DEBCONF-SET-SELECTIONS(1)

NAME
debconf-set-selections - insert new default values into the debconf database SYNOPSIS
debconf-set-selections file debconf-get-selections | ssh newhost debconf-set-selections DESCRIPTION
debconf-set-selections can be used to pre-seed the debconf database with answers, or to change answers in the database. Each question will be marked as seen to prevent debconf from asking the question interactively. Reads from a file if a filename is given, otherwise from stdin. WARNING
Only use this command to seed debconf values for packages that will be or are installed. Otherwise you can end up with values in the database for uninstalled packages that will not go away, or with worse problems involving shared values. It is recommended that this only be used to seed the database if the originating machine has an identical install. DATA FORMAT
The data is a series of lines. Lines beginning with a # character are comments. Blank lines are ignored. All other lines set the value of one question, and should contain four values, each separated by one character of whitespace. The first value is the name of the package that owns the question. The second is the name of the question, the third value is the type of this question, and the fourth value (through the end of the line) is the value to use for the answer of the question. Alternatively, the third value can be "seen"; then the preseed line only controls whether the question is marked as seen in debconf's database. Note that preseeding a question's value defaults to marking that question as seen, so to override the default value without marking a question seen, you need two lines. Lines can be continued to the next line by ending them with a "" character. EXAMPLES
# Force debconf priority to critical. debconf debconf/priority select critical # Override default frontend to readline, but allow user to select. debconf debconf/frontend select readline debconf debconf/frontend seen false OPTIONS
--verbose, -v verbose output --checkonly, -c only check the input file format, do not save changes to database SEE ALSO
