Hi
This is one example of using recursion to solve it.
use strict;
my $path = '/var/www/html';
print "<ul>\n";
recurse_path($path, " ");
print "</ul>\n";
sub recurse_path {
my $path = shift;
my $padding = shift;
my $dir = $path;
$dir =~ s/.*\///g;
print "$padding<li><a href=\"$path\">$dir</a>\n";
my $has_subdir = 0;
foreach(glob("$path/*")) {
if(-d $_ && ! $has_subdir) {
print "$padding<ul>\n";
$has_subdir = 1;
recurse_path($_, $padding . " ")
}
elsif(-d $_) { recurse_path($_, $padding . " ") }
}
if($has_subdir) { print "$padding</ul>\n" }
}

Are you posting in the right place? Check out Where do I post X? to know for sure.

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
