Environment

System wide

Load user environment from profile

#+begin_src sh :tangle (if noninteractive "no" "/sudo::/etc/profile.d/env.sh")
# User specified environment
if [ -d ~/.config/environment.d ]; then
        for rc in ~/.config/environment.d/*; do
                if [ -f "$rc" ]; then
                        . "$rc"
                fi
        done
fi

unset rc
