A few of these tools try to give high-level interfaces while some other utilities focus on offering low-level functionality. Almost all of these packages are correlated and work on similar package databases. The Ubuntu/Debian ecosystem occupies some distinct package management tools for managing software in the system. Introduction to Debian Package Management Tools To run the apt command, we need to open the terminal window and execute the following command: This command can be used for displaying the installed package list on our system. The apt command is a packages manager (built-in) in Ubuntu that aids us to install, update, and uninstall packages from our Ubuntu system. Listing Installed Packages with apt Command There have been more package managers created for running in parallel along with the core dpkg and apt tooling: for instance, snap offers more sandboxing and portability, and Homebrew, which shifted from macOS, offers command-line tools which could be installed by single users to ignore conflicts with system packages. The other big family, used by Ubuntu, Debian, and related distros, uses the packaging format, i.e. The RPM packaging tools and packaging formats such as yum and rpm are common for Red Hat Enterprise Linux-based distros (like Rocky Linux and RHEL itself). The package management tools and the packaging format differ from one distribution to another, but almost all distributions apply one of two tool sets. Package management is one of the essential aspects of a Linux system. We can use the keyword shortcuts, i.e., Ctrl+Alt+T to start the Terminal. We will use the Ubuntu Terminal windows to execute the commands. We will learn how we can list the packages installed on our system in this article. We might sometimes want to list the packages installed on our system. Also, we have probably installed other packages for enhancing the functionalities of the system. Many packages come pre-installed in a newly installed Linux system. We might be wondering where the packages come from. Several packages are installed on our Linux system. The Ubuntu packages are a group of items (libraries, scripts, text files, license, a manifest, etc) that enable us to install a segment of software ordered in a way that a package manager will be able to unpack it and bring it into our system.
