One liner to watch the current folder and tree its structure

I've been working with smstools3 which uses a folder and its subfolder as its state store. 

Instead of running "tree" manually in the /var/spool/sms folder, i'd rather have it be done automagically whenever the files change.

I've used inotifywait for that, which needs to be installed on ubuntu with sudo apt install inotify-tools .

Then it's just a matter of cd-ing to the proper directory and running :

clear && tree && inotifywait --monitor --quiet --recursive --event modify . | while read; do clear; tree; done

Screenshot of the result, it will refresh whenever files change
