Two monitor setup
Averagepenguin  describes a method of moving windows between two monitors. I was hit by two gotchas:
- at the font size and screen resolution that I use and with my poor eyesight, the backticks (`) looked like single quotes ( ‘ ). Since I had no knowledge of the command substitution concept  (being a noob and all), the xdotool command didn’t work. I was puzzled. In the end I took a wild guess: maybe ‘ was really ` and it worked. Sometime later I grew suspicious, went back to the site and increased the font size significantly, lo and behold it was very obvious.
- in the bash script, we need spaces around the brackets [ ], otherwise it wont work. See .
