Well, this is actually very experimental for me because I have actually no idea about bash scripting, but it appears to be working. I only tested it on Ubuntu and it worked perfectly, but I'm not a programmer so neither my code is nice nor I know if I'll be able to port every single function to it (specially to macOS).
I just hope our friends on other OSs than Windows have now an easier way to scrape than before.
From the command-line type the following to set appropriate permissions if needed:
chmod u+x ./fastscraper
Any feedback is very welcome!
