debconf is a software utility for performing system-wide configuration tasks on Unix-like operating systems. It is developed for the Debian Linux distribution, and is closely integrated with Debian's package management system, dpkg.
When packages are being installed, debconf asks the user questions which determine the contents of the system-wide configuration files associated with that package. After package installation, it is possible to go back and change the configuration of a package by using the dpkg-reconfigure program, or another program such as Synaptic.
The design of debconf allows for front-ends for answering configuration questions to be added in a modular way, and there exist several, such as one for dialog, one for readline, one that uses a text editor, one for KDE, one for GNOME,[2] a Python front-end API, etc.
The original implementation of debconf is in Perl. During the development of Debian-Installer, a new implementation in C was developed, which is named cdebconf. The new implementation is currently only used in the installer, but is intended to eventually replace the original entirely. Both implementations make use of the same protocol for communication between the debconf front-end and the client code ("confmodule"); this is a simple line-based protocol similar to common Internet protocols.
Debconf does not physically configure any packages, but asks the user certain configuration questions stored in the .templates file, under the direction of the package's maintainer scripts (.config, .postinst, etc.). Typically, the .config script uses debconf to ask questions, while .postinst applies configuration changes to the unpacked package in reaction to the answers; however, this can vary due to technical requirements. The user's answers to the configuration questions asked by debconf are cached in debconf's database.

A system configuration (SC) in systems engineering defines the computers, processes, and devices that compose the system and its boundary. More generally, the system configuration is the specific definition of the elements that define and/or prescribe what a system is composed of. Alternatively, the term "system configuration" can be used to relate to a model (declarative) for abstract generalized systems. In this sense, the usage of the configuration information is not tailored to any specific usage, but stands alone as a data set. A properly-configured system avoids resource-conflict problems, and makes it easier to upgrade a system with new equipment.
For system configuration in general see System configuration. For the Microsoft Windows System Configuration utility see MSConfig.
A Unix shell is a shell that provides a command-line user interface for a Unix-like operating system. A Unix shell provides a command language that can be used either interactively or for writing a shell script. A user typically works within a Unix shell via a terminal emulator; however, direct access via serial hardware connections or a Secure Shell are common for server systems. Although use of a Unix shell is popular with some users, others prefer to use a graphical shell in a windowing system, such as those provided in desktop Linux distributions or macOS, instead of a command-line interface (CLI). A user may have access to multiple Unix shells with one configured to run by default when the user logs in interactively. The default selection is typically stored in a user's profile (for example, in the local passwd file or in a distributed configuration system such as NIS or LDAP). A user may use other shells nested inside the default shell. A Unix shell may provide many features including: variable definition and substitution, command substitution, filename wildcarding, stream piping, control flow structures (condition-testing and iteration), working directory context, and here document.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
