In case you need to search recursively, you may use the File::Find core module:
use strict;
use warnings;
use File::Find;
# Search current dir unless dir(s) given as command line args
@ARGV = qw(.) unless @ARGV;
find( \&get_dirs_with_numbers, @ARGV );
sub get_dirs_with_numbers {
return unless /^\d+$/; # your regex
print $File::Find::name . "\n";
}
find function from File::Find scans directories in @ARGV recursively and for each file calls the referenced function (coderef) get_dirs_with_numbers. Before calling your function find by default changes to the directory being scanned and sets the following variables:
- $File::Find::dir -- visited directory path relative to the starting directory
- $_ -- basename of the file being visited
- $File::Find::name -- full path of the file being visited

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).
