I have several repositories enabled on my system and want to identify any stale or unused ones so I can safely disable them.

Here is my current list of enabled repository IDs:

brave-browser
cloudflare-warp-stable
code
copr:copr.fedorainfracloud.org:phracek:PyCharm
docker-ce-stable
fedora
fedora-cisco-openh264
google-chrome
protonvpn-fedora-stable
rpmfusion-free
rpmfusion-free-updates
rpmfusion-nonfree
rpmfusion-nonfree-nvidia-driver
rpmfusion-nonfree-steam
rpmfusion-nonfree-updates
updates

Try

dnf list --installed |awk '{print $3}' | sort -u
