Would it be faster if you do reading and moving using a shell script?
Something like:
for afile in $dir/*; do
achannel=$(awk -F'|' '{print $20}' "${afile}")
mv "${afile}" "${outdir}/${achannel}"
done
Unlikely. Creating an awk and a mv process for each of half a million files sums up to spawning a million processes. I doubt that this idea will be faster than running a single process (perl script), even on an insanely fast machine.

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).

or How to display code and escape characters
are good places to start.
