I am sorry if I am wrong, but it sounds like your only interest in Perl is a solution to yesterday's problem. If so, you probably have come to the wrong place. We are here to help you solve it yourself. You received two good answers. The first was the terse one-line program you have repeated here along with a link to the documentation needed to understand it. Once you understand it, you should be able to adapt it to your needs without executing perl from within perl. (Did you notice that it omits the final ');'? ) The other answer is much longer, but easier to understand. You may even be able to cut and paste the parts that you need.

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).

or How to display code and escape characters
are good places to start.
