I know you're just tossing that code off quickly, but I'm curious to know why you chose to write:
while (<>) {
my ($f) = (split)[6];
$count{$f}++;
}
...rather than...
while (<>) {
$count{(split)[6]}++;
}
It makes me wonder if there's some robustness principle at work that eludes me. And of course, there is even...
$count{(split)[6]}++ while <>;
... but then we are getting into the realms of the cryptic, and I don't seen a more concise way of printing the top N values that doesn't sacrifice economy.

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).
