        The pattern definition is as follows:

        *             Matches any number of any characters
        ?             Match exactly one character

        </pre>
        The literal characters *, ?, [, ] can be included in a string by
        escaping them with backslash "\".  Ranges of characters can be concatenated.
        <pre>
        examples:
