Your code at present will disregard a matching string on the first line. In addition, you read in the entire file at once, sucking up a good deal of memory if the file is quite large. Here's another way of doing it:
#!/usr/bin/perl -w
use strict; # Or don't. See if I care.
while (<>) {
print if (/[Aa]/ && /[Ee]/ && /[Ii]/ && /[Oo]/ && /[Uu]/);
}
I only used the character classes there because (I hear) they're faster than /i matches. Could be wrong on that count, though.

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).
