if the variable name is really "variable", then none. > I have read sh(1) and understand than ${} is a "parameter" and can > contain more than just a variable, but browsing through /etc/rc I see > lots of "${variable}" (i.e. "case ${svc_val} in"). > > Is this just for readability or is there some functional difference? sh(1): The simplest form for parameter expansion is: ^^^^^^^^^^^^^^^^^^^ ${parameter} The value, if any, of parameter is substituted. The parameter name or symbol can be enclosed in braces, which are ^^^ optional except for positional parameters with more than one digit ^^^^^^^^ or when parameter is followed by a character that could be interpreted as part of the name. so yes, it's mostly a matter of style. -- If you cc me or remove the list(s) completely I'll most likely ignore your message. see http://www.eyrie.org./~eagle/faqs/questions.html To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-questions" in the body of the message
