The easist way to do this is to use fdopen from IO::Handle:
use IO::Handle;
open INPUT, '<', "input.txt" or die $!;
open OUTPUT, '>', "output.txt" or die $!;
open ERROR, '>', "error.txt" or die $!;
STDIN->fdopen( \*INPUT, 'r' ) or die $!;
STDOUT->fdopen( \*OUTPUT, 'w' ) or die $!;
STDERR->fdopen( \*ERROR, 'w' ) or die $!;
# prints to output.txt:
print "Hello Output File\n";
# reads everything from input.txt and prints it to output.txt:
print <>;
# prints to error.txt:
warn "Hello Error File\n";

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).
