Find out what packages are installed on your Fedora system

Read Time:11 Minute, 1 Second

If you’re curious about how many packages are installed on your Fedora system or how you can check on them, you might be surprised at how much information you have at your fingertips. With just a few commands, you can find out just about anything you might want know about packages and the repositories they came from.

What is a package?

To get started, a Linux package is simply a collection of files that performs some particular tasks. For example, the popular image-editing program GIMP is installed as a package, and it includes all of the files that you need to do some impressive image editing. You can easily ask if GIMP is installed with a command like this:

$ which gimp

/usr/bin/gimp

On the other hand, you can also ask about GIMP with a command like this and uncover more details:

$ sudo dnf list gimp

Installed Packages

gimp.x86_64 2:2.10.24-1.fc34 @fedora

This command provides more details on the package including its package name and that it’s the 64-bit version of the x86 instruction set.

Using dnf

As you might know, dnf replaced yum some years ago. Even if you type “yum” on the command line these days, you’re probably using dnf. The command below shows that yum is simply a symbolic link to dnf.

$ ls -l /usr/bin/yum

lrwxrwxrwx. 1 root root 5 Jun 15 05:17 /usr/bin/yum -> dnf-3

In case you’re wondering, dnf also points to dnf-3 (the current version of dnf).

$ ls -l /usr/bin/dnf

lrwxrwxrwx. 1 root root 5 Jun 15 05:17 /usr/bin/dnf -> dnf-3

To find out about all of the packages that comprise GIMP, use a command like this:

$ sudo dnf list installed | grep gimp

gimp.x86_64 2:2.10.24-1.fc34 @fedora

gimp-libs.x86_64 2:2.10.24-1.fc34 @fedora

The output above lists two GIMP packages. The second contains the libraries. That “2.10.24” in the middle fields indicates the release that is installed, which is the latest stable version of this tool. The “fc34” string indicates that these packages are meant for Fedora 34.

To list more installed packages, you can run a command like this:

$ sudo dnf list installed | head -11

Installed Packages

AtomicParsley.x86_64 0.9.5-17.fc34 @fedora

Box2D.x86_64 2.4.1-5.fc34 @fedora

LibRaw.x86_64 0.20.2-2.fc34 @fedora

ModemManager.x86_64 1.16.6-1.fc34 @updates

ModemManager-glib.x86_64 1.16.6-1.fc34 @updates

NetworkManager.x86_64 1:1.30.4-1.fc34 @updates-testing

NetworkManager-adsl.x86_64 1:1.30.4-1.fc34 @updates-testing

NetworkManager-bluetooth.x86_64 1:1.30.4-1.fc34 @updates-testing

NetworkManager-config-connectivity-fedora.noarch 1:1.30.4-1.fc34 @updates-testing

NetworkManager-libnm.x86_64 1:1.30.4-1.fc34 @updates-testing

This display lists the packages and release information and, on the far right, it references the repositories from which these packages were derived or last updated.

If you’re curious about how many packages will be listed when you run the command without piping its output to the head command, try this:

$ sudo dnf list installed | wc -l

1901

This shows you that, on this system, 1900 packages are installed (1901 includes the “Installed Packages” heading).

To get a feel for how many repositories are involved and how many packages/updates are associated with each, you can try a command like this:

$ sudo dnf list installed | grep -v ‘^Installed’ | awk ‘{print $3}’ | sort | uniq -c

1 @anaconda

983 @fedora

3 @fedora-cisco-openh264

705 @updates

207 @updates-testing

The lines show package counts by source repository. You can also get a list of information on repositories like this:

$ sudo dnf repolist

repo id repo name

fedora Fedora 34 – x86_64

fedora-cisco-openh264 Fedora 34 openh264 (From Cisco) – x86_64

fedora-modular Fedora Modular 34 – x86_64

updates Fedora 34 – x86_64 – Updates

updates-modular Fedora Modular 34 – x86_64 – Updates

The first line shows the headings for the list. If you add a -v (e.g., sudo dnf repolist -v), you’ll see a lot more detail on each repository. The command below provides details for the first listed repository.

$ sudo sudo dnf repolist -v | head -15

Checking out the “extras”

To list packages which are installed on your system, but not associated with any repository listed in the config file, use a command like this:

$ sudo dnf list –extras

To list all available packages in enabled repositories, do this:

$ sudo dnf list –available | wc -l

63490

Comparing these numbers can point out how few packages are installed compared to how many are available.

$ sudo dnf list –installed | wc -l

1901

$ sudo dnf list –all | wc -l

65391

$ sudo dnf list –available | wc -l

Wrap-up

Linux distributions include thousands of packages with many thousands more available. On Fedora and related distros, the dnf command can provide a lot of detail on the packages installed on your system and the repositories in use.
