dpkg

Dpkg is a command-line tool for managing Debian packages in Linux operating systems. It is used to install, remove, and manage software packages on Debian-based systems, including Ubuntu. Dpkg stands for "Debian package". It is a low-level package management tool that works with the core package format of Debian and its derivatives. The tool is part of the dpkg package management system, which includes other tools like apt and apt-get. Dpkg handles the installation, configuration, and maintenance of packages on a Linux system. It can be used to query package information, list installed packages, and check the status of packages. Dpkg supports various package formats, including .deb files, which are the standard package format used in Debian-based distributions. The tool has a wide range of options and flags to perform different tasks, such as force installation, removal, and upgrading of packages. Dpkg works directly with the package database and system files, ensuring package integrity, dependencies, and conflicts are properly managed. It is primarily a command-line tool, but there are also graphical front-ends available that provide a user-friendly interface to dpkg functionality.
