A lot of the other replies show how you can process the data after you've read it. But perhaps it might be better to process that data as you read it. Like this:
#!/usr/bin/perl -w
use strict;
my @search;
my $query = qr/perl/;
open FILE, "file" or die "Error message here: $!";
while (<FILE>) {
push @search, $_ if /$query/;
}
chomp @search; # If required
close(FILE);
Also, the qr// operator is useful for pre-compliling a regular expression that will be used as a variable. See perlop for details.

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).
