@pwired and all forum members
I decided to put together my own bash script because I did not find what I was after. I am not a bash pro nor a linux/unix guru, so there might be better solutions using standard system tools, but I like the result so I thought I share it with you. You might also find it useful.
Here is a short demo: https://youtu.be/V6eF4NBNDbc
Please read the instructions (located in the script itself) if you happen try it out!
Any constructive criticism is welcome.
