I'm attempting to add the mozilla repos to apt (on Debian Trixie) and got confused when I reached the step on actually adding the repository to the sources file, where it has me using this command:
cat <<EOF | sudo tee /etc/apt/sources.list.d/mozilla.sources
Types: deb
URIs: https://packages.mozilla.org/apt
Suites: mozilla
Components: main
Signed-By: /etc/apt/keyrings/packages.mozilla.org.asc
EOF
Is it asking me to run the whole prompt in the CL? Or only the first line, then input the rest of it? If it's the latter how do I save the changes? Same applies to the step after, cause I think it's formatted the same way. Actual page for reference:
