NewLine:
This is a really good idea!
However I would rather just run/tweak the Linux script instead of via the sketch. Any Chance of publishing this? If not, I'll extract it from the sketch myself.
We decided to adopt the "Arduino sketch way" to keep the procedure as simple as possible (means you don't have to deal with the Linux terminal).
I'm sorry but we are not going to publish a Linux bash script with the same commands. However, extracting them form the sketch is very simple.
