Further to GrandFather's remarks:
The regex /^[5]+$/ does not match the string
'503009496', but is there any other string it would match?
What about the strings
5
55
555
555555555
If you find some strings that match, how would they and the strings
you know do not match interact with the regex components
mentioned by GrandFather? Please see perlre,
perlretut, perlrequick and perlreref.
Give a man a fish: <%-{-{-{-<

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
