I can list installed packages on my Fedora with:

dnf list installed

When searching for packages, I'd use something like:

dnf search terminal

dnf will proceed to list available packages similar to this:

tmux.x86_64 : A terminal multiplexer

i.e. "<package> : <summary>". I'd like to have a similar output of packages, but for installed packages. Search among installed packages is not necessary, as I can simply pipe the output into grep (or ripgrep), but an output like the one that results from a search is something I'd like to have.

The rpm database is already a collection of all your installed packages.

You can query the database directly with rpm and extract any available information using the --queryformat option without using any additional tools or loops:

rpm --query --all --queryformat '%{NAME}.%{ARCH}: %{SUMMARY}\n'

Adjust --queryformat to use whatever information rpm provides: http://ftp.rpm.org/api/4.4.2.2/queryformat.html

Something like

for pkg in $(dnf list --installed) ; do
  rpm -q --queryformat '%{NAME} : %{SUMMARY}\n' ${pkg}
done

might do the trick (untested, since written on a phone).

The for ... do ... done loop is of course a bit over the top, but it does allow you to do some extra filtering if you want to, log things, surround them in proper HTML, whatever your heart desires

  • Right, I'm assuming a command purely reliant on dnf isn't possible? Commented Aug 3, 2022 at 1:31

  • Thanks, that explains a bit. For now I'm using dnf list --installed | cut -f1 -d' ' | xargs -I '{}' rpm -q --queryformat '{} : %{SUMMARY}\n' '{}' based on your suggestion. I'll see if someone else comes up with something insightful for a day or two before accepting. Commented Aug 3, 2022 at 1:45

    Since rpm already has a database of all the installed packages, should be no need for additional tools or loops: rpm -qa --queryformat '%{NAME}.%{ARCH}: %{SUMMARY}' Commented Aug 3, 2022 at 1:58
