Just for information, if you have more then one screen, the second screen,
just change screen0 to screen1. I go till screen3.
Question: I know how many screens I have, but how could I find this out
with a bash script? I do not mean running `echo $DISPLAY` on each and then
looking what the highest number is. I mean that I should get an output of
4 (or 3 if it starts counting from 0) with my 4 screens and if I have 2 on
another system, I get the answer 2 with the same script/command.
If you owe the bank $100 that's your problem.
If you owe the bank $100 million, that's the bank's problem.
If you owe the bank $700 billion, it becomes your problem again.
