I'm not sure how to do this exactly with a regex but one could use something like: -
use strict;
my @names = (
'Joe John Smith',
'David George',
'Emma Harry Sally Martin',
);
foreach (@names) {
my @w = split /\s/, (/\s+(\w[\w ]{0,18}\w)\s*$/)[0];
shift @w while @w > 2;
print "@w\n";
}
Update: You can replace everything in the foreach scope with: -
(/\s+(\w[\w ]{0,18}\w)\s*$/)[0] =~ /(\w+\s?\w+)$/g;

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).
