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.

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).
