Package management is one of the most common operation for any Linux users. Although Linux does come pre-installed with a suite of good and useful tools, you will encounter yourself installing custom packages on your system.
APT List Installed Packages
Advanced Packaging Tool, or APT, is a command-line utility that allows you to install, uninstall, update and manage packages on Debian based systems. It is one of the most popular packages in Debian systems such Ubuntu, Linux Mint, !Pop OS, etc.
To list installed packages on Debian systems using
apt, run the comand as shown:
sudo apt list --installed
The command should list all the packages installed on the target system.The command may contain a lot of output. You can pipe the output to other tools such as
For example, to show the first 10 packages, run the command:
sudo apt list --installed | head -10
Listing... adduser/stable,now 3.118 all [installed] apt-utils/stable,now 2.2.4 amd64 [installed] apt/stable,now 2.2.4 amd64 [installed] base-files/now 11.1+deb11u3 amd64 [installed,upgradable to: 11.1+deb11u5] base-passwd/stable,now 3.5.51 amd64 [installed] bash/now 5.1-2+b3 amd64 [installed,upgradable to: 5.1-2+deb11u1] bsdutils/stable,stable-security,now 1:2.36.1-8+deb11u1 amd64 [installed] ca-certificates/stable,now 20210119 all [installed,automatic] coreutils/stable,now 8.32-4+b1 amd64 [installed]
The output above includes other details such as the state under which the package was installed:
installed- this indicates that the package was installed manually by the user.
installed,automatic- the package was instaled automatically as a dependency.
installed,local- the package was installed via local method and not from official repository. An example would be a
Apt Show Specific Package Details
You can also pass the package name to the apt command to show the details about that package. An example is as shown:
sudo apt list curl -a --installed
Listing... Done curl/bullseye-backports 7.85.0-1~bpo11+1 amd64 curl/stable,now 7.74.0-1.3+deb11u3 amd64 [installed] curl/stable-security 7.74.0-1.3+deb11u2 amd64
DNF Show Installed Packages
Dandified YUM, or simply DNF, is the successor to the popular Yellowdog Updater, Modified package manager, more commonly known as YUM. It is a popular package manager in REHL systems such as RedHat Enterprise Linux, CentOS, Fedora, etc.
You can learn how to use DNF in the link below:
To show the installed packages in DNF, run the command:
dnf list installed | head -10
The command show list the top 10 installed packages on your system. An example output is as shown:
Installed Packages NetworkManager.x86_64 1:1.39.7-2.el9 @anaconda NetworkManager-libnm.x86_64 1:1.39.7-2.el9 @anaconda NetworkManager-team.x86_64 1:1.39.7-2.el9 @anaconda NetworkManager-tui.x86_64 1:1.39.7-2.el9 @anaconda PackageKit.x86_64 1.2.4-2.el9 @koji-override-1 PackageKit-glib.x86_64 1.2.4-2.el9 @koji-override-1 abattis-cantarell-fonts.noarch 0.301-4.el9 @koji-override-1 acl.x86_64 2.3.1-3.el9 @anaconda adobe-source-code-pro-fonts.noarch 2.030.1.050-12.el9.1 @koji-override-1
This shows the installed package, version and the source.
DPKG Show Installed Packages
Another common package manager for Debian systems is DPKG.
To show installed packages with dnf, run the command:
dpkg --get-selections | grep -w "install" | head -10
In this case, we use the
--get-selections parameter to show the list of package selections to standard out. We then pipe the output to grep to filter for the installed packages.
An example output is as shown:
adduser install apt install apt-utils install base-files install base-passwd install bash install bsdutils install ca-certificates install coreutils install cpio install
If you do not wish the above command chaining, you can use the
dpkg-query command for similar operation.
The command is as shown:
The command should display detailed information about the installed packages, including description and architecture.
