First the obligarory use File::Find. Anyway here is how to do it without using recursion - it is presented as an example rather than a recommendation. Search is width first rather than depth first. It is vaguely interesting in that we add new dirs to the array we are currently looping over. This comes in handy for other things as well.
#!/usr/bin/perl -w
use strict;
my $root = "c:\\cl";
my $delim = $^O =~ m/Win32/ ? "\\" : "/";
$root .= $delim unless $root =~ m!\Q$delim\E$!; # ensure we have trail
+ing slash
my @dirs = ($root);
my @files;
for my $path (@dirs){
opendir ( DIR, $path ) or next; # skip dirs we can't r
+ead
while (my $file = readdir DIR) {
next if $file eq '.' or $file eq '..'; # skip the dot files
next if -l $path.$file; # skip symbolic links
if ( -d $path.$file ) {
push @dirs, $path.$file.$delim; # add the dir to dir l
+ist
}
else {
push @files, $path.$file; # add the file to file
+ list
}
}
closedir DIR;
}
do{ local $"=$/; print "Directory list\n@dirs\n\nFile List\n@files\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).
