Matthew,

   That's great for a first attempt. :-)

One small convenience hint:

msg=""call with 1 for single monitor, 2 for multimonitor."

Then in two places:

echo $msg

This avoids the subsequent maintenance hassle of changing one, but
forgetting the other.

I don't know whether the following offers anything that would appeal:

cmd=${0##*/}                              # Command's basename
msg="\n\tUsage: $cmd [1|2]\n\t\t1 = single monitor\n\t\t2 = multimonitor"

That's all a matter of taste, except I find that separation by a blank
line has a highlighting effect, and several lines of output jangle my
optic nerves sufficiently to actually stimulate reading. (Your eyesight
and attention may be better than mine. :-)

Happy hacking,

Erik
