How to check a list of packages installed on Linux

As we know, package managers are one of the most contributors to the Linux system.

Most of us prefer the command line interface for package management such as the YUM command, DNF command, APT command, Apt-Get command, PACMAN command, and ZYPPER command based on Linux distributions.

Package Manager allows us to perform actions such as installing new software packages, removing unused software packages, updating the existing software packages, searching for specific software packages, and updating the system to latest available version, etc.

As a system administrator you should keep track of the packages installed on the system, which can save you a lot of time when setting up a new server or migrating them.

Since we already have the list, this list will help you to quickly install the required packages.

Many tools are used to manage packages on Linux, from the graphics or text-based interface to the lower-level tools used to install packages.

This is a very short and powerful exercise for newbie to manage package management.

In this tutorial we will include all major Linux distributions such as RHEL (RedHat), CentOS, Fedora, Debian, Ubuntu, openSUSE and Arch Linux systems.

1) How to List All Packages Installed on RPM Based Systems Using the RPM Command

You can use the RPM command with the -qa option to get a list of packages installed on RHEL (RedHat), CentOS, Fedora, and openSUSE systems.

RPM stands for RPM Package Manager formerly known as Red Hat Package Manager is a powerful package management system for Red Hat Enterprise Linux (RHEL) as well as other Linux distribution such as Fedora, CentOS, and openSUSE. RPM maintains a database of installed packages and their files, so you can invoke powerful queries and verification’s on your system.

$ rpm -qa
$ rpm -qa --last

2) How to Check All Packages Installed on RHEL (Red Hat) and CentOS Systems Using the YUM Command

Use the following YUM command to get the list of packages installed on RHEL (RedHat) and CentOS systems.

YUM stands for Yellowdog Updater, Modified is an open-source command-line front-end package-management utility for RPM based systems such as Red Hat Enterprise Linux (RHEL) and CentOS.

Yum is the primary tool for getting, installing, deleting, querying, and managing RPM packages from distribution repositories, as well as other third-party repositories.

5) How to Check All Packages Installed on Arch Linux Based Systems Using the Pacman Command

Use the following Pacman command to get a list of packages installed on Arch Linux based systems such as Manjaro, ArcoLinux, Chakra, etc.

Pacman stands for package manager utility. pacman is a simple command-line utility to install, build, remove and manage Arch Linux packages. Pacman uses libalpm (Arch Linux Package Management (ALPM) library) as a back-end to perform all the actions.

6) How to List All Packages Installed on Deb Based Systems Using the DPKG Command

We can use the DPKG command to get a list of packages installed on Debian based systems such as Ubuntu and LinuxMint.

DPKG stands for Debian Package is a tool to install, build, remove and manage Debian packages, but unlike other package management systems, it cannot automatically download and install packages or their dependencies.

$ dpkg -l
$ dpkg-query -l
$ dpkg --get-selections | grep -v deinstall

7) How to Find All Packages Installed on Deb Based Systems Using the Apt Command

Use the following Apt command to get a list of installed packages on Debian based systems such as Ubuntu and LinuxMint.

APT (Advanced Packaging Tool), a higher level tool, is more commonly used than dpkg as it can fetch packages from remote locations and deal with complex package relations, such as dependency resolution.

$ apt list --installed

  1. “apt-cache pkgnames” shows all available packages, not only the installed packages. From its man page:

    “This command prints the name of each package APT knows […] Note that a package which APT knows of is not necessarily available to download, installable or installed”
