Thom, I wasn't implying anything about your knowledge.  I just meant that my
suggested modification made sense to me b/c I assumed any user (you
included) would not ever supply an empty argument enclosed in quotes.  This
script was so short it doesn't matter much, but you're not the only one who
will read the post and I thought my comment would benefit at least a few
others.  For those new to shell scripting (or programming for that matter) I
thought there might be some benefit in mentioning that IMO some of the code
was redundant.  If instead of a script with 3 arguments we had one with 9
and we only wanted to execute it if the user supplied 9 arguments, in some
cases all that's required is to check that the 9th argument exists.  And if
I wanted to check each argument I'd use a loop.  YMMV.

Yes it was.  And Eric did a great job and was lightning fast in replying.
In fact I got his response before your original post!  I wasn't trying to
step on toes, I was just trying to share my knowledge.
