Here's a way to get rid of the warnings, but really you need to reconsider the whole approach used in the while loop. That code is a mess.

By declaring lexical variables inside the loop, they get reset each time through. Move the declarations out of the loop for them to persist.

my (@values1,@val1,@values2,@val2); while (<CMD>) { ...
You will still get one warning from line 1, because the code after the if loop is executed for all lines and @val2 is not yet defined. Adding next can fix that.
my (@values1,@val1,@values2,@val2); while (<CMD>) { if ( $_ =~ /PING/ ){ @values1 = split ; @val1 = split(/\(/,$values1[3]); $val1[1] =~ s/\)//; next; } ...

Again, while these changes avoid the warnings and hopefully show you why they happened, the entire while loop needs a rethink.

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.
