I am not pressed to chase this down since I've done what I needed with app browser. What follows is FYI should it matter or be helpful to someone else.
In terminal:
>version
5.4
>ls /usr/bin/ | head -n 8
[
[[
ar
arping
autoscan-devices
awk
backup
basename
>which apps-audit
(no output)
Thank you for your replies!
