Hi,
From how I understood your question, you want to get the total for each columns... So, I replaced this code
for my $to (sort keys %from_to_bytes){
printf "%10s", "$from_to_bytes{$to}";
}
with this one.
my %total_col;
for my $i (keys %from_to_bytes) {
for my $j (keys %{ $from_to_bytes{$i} }) {
$total_col{$j} += $from_to_bytes{$i}->{$j};
}
}
print " " x 11;
for my $i (sort keys %total_col) {
printf " %10s", "$total_col{$i}";
}
print "\n";
Although as you can see there is some more work needed in the formatting. Hope this helps.

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).
