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.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • 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.
