Nice. Similar to something I run here except for the shutdown.

One thing to think about. Each time your script runs it regenerates a new .lst file
This means if a file is changed early during boot or during shutdown then on the next time your script runs it will regenerate the *.lst files and all will appear normal.
How do i become super user?
Wear your underpants on the outside and put on a cape.

yes, and before a shutdown i delete all *.lst and remove ramdisk folder, when at first i have idea to write this script i find that hardisk was heavy load, after i create ramdisk for minimize this
