Look at the preprocess option in the documentation.
The code can be used to sort the file/directory names alphabetically, numerically, or to filter out directory entries based on their name alone.
You can pre-process a directory and remove entries for backup directories based on a regex or lookup. File::Find will only follow and process the list of files/directories that are returned by this method.
The example below prints out all files and directories that start with A-D.
#! /usr/bin/perl
use strict;
use warnings;
use File::Find;
find ({wanted => \&wanted, preprocess=> \&preproc, no_chdir=>1}, @ARGV
+);
sub wanted {
print "wanted $_\n"
}
sub preproc {
# print "Pre processing $_\n" foreach (@_);
return grep {/^[A-Da-d]/}@_;
}

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).
