You could also reduce memory overhead (at the expense of more calls to rand) by doing your random keep/toss within the loop:
my $lines = 0;
my $selection;
foreach my $path (split /:/, $ENV{'PATH'}) {
opendir(PATH, $path);
while (defined($_ = readdir(PATH))) {
if (-f "$path/$_") {
++$lines;
$selection = $_ if int(rand($lines)) == 0;
}
}
closedir(PATH)
}
exec(man => $selection);
We're not really tightening our belts, it just feels that way because we're getting fatter.

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.
