Hi,
I am tring to sort the hash with values below is the code:
sub mySort {
$a =~ /(\d+)/;
my $firstVal = $1;
$b =~ /(\d+)/;
my $secVal = $1;
$firstVal <=> $secVal;
}
my %IP_Store = (
"11.0.0.1" => "UEH1_system_ip",
"11.0.0.11" => "UEH11_system_ip",
"11.0.0.3" => "UEH25_system_ip",
"11.0.0.25" => "UEH111_system_ip"
);
foreach my $Value (sort mySort (values (%IP_Store))) {
print "$Value\n";
print "System_ip = '$IP_Store{$Value}' \n";
#print "PDN-IP = '$Values' \n";
}
when i run this script getting these warnings. and in "system_ip" values are also not coming.
UEH1_system_ip
Use of uninitialized value within %IP_Store in concatenation (.) or st
+ring at C:\Users\Desktop\IP_test\test123.pl line 30.
System_ip = ''
UEH11_system_ip
System_ip = ''
UEH25_system_ip
System_ip = ''
UEH111_system_ip
System_ip = ''
Use of uninitialized value within %IP_Store in concatenation (.) or st
+ring at C:\Users\Desktop\IP_test\test123.pl line 30.
Thanks in advance

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).

are good places to start.
