Basic case (in)sensitive pattern matching. Supported wildcard characters: * - matches 0 or more any characters ? - matches exactly 1 any character # - matches any digit, 0-9 [list] - matches any character in <list> (l, i, s and t in this example) [!list] - matches any character that isn't in the list Use \\* or \\? or \\[ to match a * or ? or [ respectively. To get a ] in a list, put it as first character of the list. To get a ! in a list, don't put it first. By common convention, special characters *, ? and # have no meaning when used in a list. If "case" is true, the matching is case sensitive.
