By default, pattern matching is case-sensitive. To override the default case-sensitivity, use the case variable. This variable can be used at the beginning of a script or at the beginning of a rule, before any pattern matching. The syntax of the case variable is:


To match case-sensitive patterns, set case equal to exact. For patterns where case does not matter, set case equal to ignore.

If a case variable is placed before all of the rules, the case setting applies to all rules. This can be overridden in a rule by using another case variable.
