Overview

Linux is a famous family of open-source Unix-like operating systems. It has its root as the Linux kernel manages a system’s resources, hardware, software memory, etc.

dpkg is a command tool offered by the Linux command line to manage Debian systems packages. It is a command tool for installation, building, removing, and managing Debian-based packages. So, it carries operations for .deb packages through the Linux terminal.
