When a Net::FTP operation fails, you really want to get the error details so you know what failed. It always takes me a while to find the details in the Net::FTP docs so I thought I'd post here:

Initial Connection: the connection is established when you create the object. If the connect fails, new() will return undef and the error message will be in $@:

my $ftp = Net::FTP->new($destserv) || die "Connect to $destserv failed: $@";

Commands: if a command fails, the method return value will be undef. The error message can be accessed using the 'message()' method. If you're checking for a particular message, you might be better off using the 'code()' method to get the three digit FTP protocol status code which preceded the message:

$ftp->get($file) || die "get($file) failed: " . $ftp->code() . ": " . $ftp->message();

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 or How to display code and escape characters are good places to start.
