When managing a Linux system, especially those based on Debian or its derivatives like Ubuntu, understanding how to interact with the package system is vital. While many users are familiar with high-level tools such as apt, dpkg-query provides more granular control and insight into DEB packages. In this blog post, we will delve into the capabilities of dpkg-query, and touch upon how commands might differ with other package managers like dnf (used in Fedora) and zypper (used in openSUSE). dpkg-query is a command-line tool included with the dpkg package management system, which is the backbone of Debian package management.

When you're managing Debian or Ubuntu systems, staying on top of the installed software packages is a crucial task. Whether you're a system administrator, a developer, or just a curious user, understanding how to leverage the Debian package management system, particularly through the dpkg command-line tool, is fundamental. Today, I'll guide you through the essentials of using dpkg to find installed packages, making sure you can easily get a glimpse of your system's software inventory. dpkg is the core package management system in Debian-based Linux distributions. It is a powerful tool used to install, remove, and provide information about .deb packages.
