Being a paranoid programmer myself, I always use: sub remove_trailing_newline {
$_[0] =~ s/[\r\n]+\Z//;
}
no matter which platform I am on. A real trick is trying to find blank lines in a slab of (multiline) text: if ( m/(\r\n|\n\r|\r|\n)$1/ ) {
# two newlines in a row!
}
Update: Thanks to rev_1318 for pointing out that the $1 need be replaced with \1 in the regexp.

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).
