Can anyone tell me of a better way to do this?
Yes. Check your arguments. This little snippet could cause havoc if called with $ snippet.pl '| rm -rf *' 'ouch'
Take a look at Two-arg open() considered dangerous for details.
My point is that specialized utilities that have been around for a long time, like grep, have more than speed going for them. In general, they'll handle edge cases better.
If you want to demonstrate "the power of Perl", remember that power can be used for good or evil. :-)

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).
