Thanks again.
Hi gencon,
I'm glad it helped.

It is a personal preference. In the shell, the meaning of (pattern) and pattern) is exactly the same. I prefer the (pattern) form because I use the vi editor (with the showmatch option set) while editing code, and if I try to match the parentheses surrounding a subshell invocation when the subshell contains a case statement, the parentheses will not match up correctly if I use the pattern) form.

Use which ever form looks better to you or works better for you.
Cheers,
Don
