Bill,
Your answer is pretty good, and is the way I used, but:
1) You need to put double quotes about the $i
if (( $(expr "$i" : ".*") > 5 ))
because the variable could contain imbedded spaces, null, etc.
2)After seeing Craig's solution, (one that I never knew about)
if (( ${#variable} > 5 ))
I think I like that even better.
