Addendum (fixed my one-liner):

And no pfb fonts:

$ shopt -s nocasematch; tot=3D0; pfb=3D0; ttf=3D0; otf=3D0; ttc=3D0; while =
read line;
do let tot+=3D1; case "${line##*.}" in ttf) let ttf+=3D1;; otf) let otf+=3D=
1;;
ttc) let ttc+=3D1;; pfb) let pfb+=3D1;; esac; done < <(gfind /Library/Fonts
/System/Library/Fonts ~/Library/Fonts -type f \( -iname "*.ttf" -o -iname
"*.ttc" -o -iname "*.otf" -o -iname "*.pfb" \) 2>/dev/null -printf "%f\n")
&& printf "\nTotal fonts=3D%s: ttf=3D%s otf=3D%s ttc=3D%s pfb=3D%s\n" "$tot=
" "$ttf"
"$otf" "$ttc" "$pfb"

Total fonts=3D447: ttf=3D296 otf=3D63 ttc=3D88 pfb=3D0

Cheers
