A lot depends on your needs. If this was a throw away script, You could do something ugly like:
system('ls -Rl ~| grep ^d');
You could look at File::Find and the -d function
If you couldn't figure out File::Find, you could do something like this:
my $DIE_MSG="FATAL ERROR";
sub get_bytes_in_file_list {
my @files = @_;
my $size=0;
foreach my $file (@files) {
die "can't read $file $DIE_MSG"
if ( !-r $file );
if ( -d $file ) {
opendir( DH, $file )
or die "$! bad open directory $file $DIE_MSG\n";
my @sub_files =
map { "$file/$_"; }
grep { $_ ne '.' && $_ ne '..'; } readdir(DH);
closedir(DH) or die "$! couldn't close dir:$file\n$DIE_MSG
+";
$size += get_bytes_in_file_list(@sub_files)
if (@sub_files) # don't check empty dir;
}
else {
$size += ( stat($file) )[7];
}
}
return $size;
}

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.
