See https://bugzilla.redhat.com/show_bug.cgi?id=713567 for info. It's
more of the systemd-mindset disease, and Schmidt looked to be pretty
intransigent in the face of concerted objection some years ago.

You either have to use: systemctl --no-pager status firewalld
Or you have to first do: export SYSTEMD_PAGER=

Maybe you could put the latter into a file in /etc/profile.d to make
it system-wide:

# echo 'export SYSTEMD_PAGER=' >>/etc/profile.d/systemd.sh
# echo 'setenv SYSTEMD_PAGER ""' >>/etc/profile.d/systemd.csh
