( #3333=superdoc: print w/replies, xml ) Need Help??
I presume you got an error message of the form Exiting subroutine via goto. Which is what you are trying to do, and isn't allowed.

I don't think you need the goto - I would check the return value of the eval, and exit if the eval succeeded. Or rather, only execute the second ping if the first failed. Something like this (untested):

# # Generalize to multiple ips # my @ips = ("", ""); $SIG{INT} = sub { print "Caught SIGINT: $?\n"; die if $?; }; foreach my $ip (@ips) { print $ip, "\n"; last if eval {`ping $ip`; 1}; }
Note that I do not wrap the eval in a pointless do construct, I'm not needing a flag variable, and I'm not storing the output of ping in a variable that I'm not going to use.

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.
