so the question was not an error on my part, just a general enquiry that I thought may have been answered with a little more understanding
Well I will point out that your question did not exhibit much thoughtfullness on your part. You did not tell us what shell you are using or what result you wanted. Futhermore it was a crosspost which is a violation of our rules. You reap what you sow. I choose to ignore your question other than deleting the duplicate post.
I still don't know what shell you're using, but the syntax that oombera suggests seems to be illegal in ksh. Some quick experiments with bash seem to suggest that it does work there, but on bash, [ and [[ just seem to be the same thing. (On the other hand, many shells will accept your original syntax.)
