I'm have a form field that I am submitting to a Perl CGI script, I want to replace all the new lines with <br> so when I redisplay the form submission in html that it formats the new lines correctly.
I have been trying each one of these because I'm not sure if it is a CR, LF, or CRLF:
$INPUT{'comments'} =~s/\n/<br>/g;
$INPUT{'comments'} =~s/\r/<br>/g;
$INPUT{'comments'} =~s/\r\n/<br>/g;
I can't seem to figure out why I can't insert any of these HTML tags into my string. How do I replace the new lines that are in the multiline text box with the HTML Break Tags?

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).
