strict and warnings won't help much when commented out, as in your post. They could have:
023: for(my $o = 0; $o<$num; $o++){
024: system ("ssh a.AS1 traceroute @dude[$0] > file"+"$0.txt ");
Had you not disabled them, you would have learned right away that $0 (twice, in Ln 24) is something other than you intended; specifically, it's the full path-name of the file being executed; and not the same as the $o instantiated in Ln 23.
Granted, the error messages and warnings would have been numerous and perhaps confusing, but the appearance of the filename might have sent you looking in the right direction.

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).
