Erik,

Thanks for the tips. New script attached. :)

I liked the use of message and the command being placed in the Usage: 
block, so I used that structure.

One minor detail you forgot to mention, that I will add here, in order 
for 'echo' to evaluate the newline and tab escapes it needs to be passed 
the -e parameter. Otherwise, everything you mentioned worked like a charm.

The output now looks like this:
myprompt$ ./multiMonitorSwitch

Usage: multiMonitorSwitch [1|2]
1 = single monitor
2 = multimonitor

myprompt$

I added an extra newline, as I like it being separated by a little bit 
from the new prompt as well. I added a bit of feedback to the other 
options as well. :)

The only thing in your email that throws me for a loop is the 
'cmd=${0##*/}'. I assume this is some kind of regular expression syntax? 
As an embedded 'C' programmer, I haven't been exposed to this kind of 
construct before.

Thanks,
-Matt
