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

  • 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.
