count the number of IP shows up in the file

sgowrish has asked for the wisdom of the Perl Monks concerning the following question:

Hi Please can someone guide me how to do this ? 1. I have a data file "path.csv" and it's contents is: 2. here basically i need to count the number of times each IP address shows up in the file based on the KEY 3. After loading above KEY:VALUES pair to HASH, i want to read IP and count based on each KEY and print into a file. I have coded something like below,i had given only the function:

 
sub _Load_IP
{
if(! open (PATH_FILE_FH, "$Path_File"))
  {
     print "Failed to Open input PATH_REPORT File: $Path_File\n";
     exit 1;
  }

 while(<PATH_FILE_FH>)
  {
   my $data =$_;
   chomp($data);

    my($pname,@val) = split(/\s+/,$data);
    my($Starpnt,$Endpnt) = split(/_/,$pname);
    $key = $Startpnt;

  #$IP_hash{$key} .= exists $IP_hash{$key} ? map{$IPcountList{$_}++ }"
+@val" : @val;

  
   $IP_hash{$key} .= "@val";


}
   
 close(PATH_FILE_FH);

} #End of  _Load_IP()

Not sure if I understand what you want to do. But here is my try. `script.pl < path.csv` `use strict; use warnings; my %h; while (<>) { my ( $k, @ips ) = split /\s+/; $k =~ s/(_.*)$//; $h{$k}{$_}++ for @ips; } for my $srv ( sort keys %h ) { for ( sort keys %{ $h{$srv} } ) { printf( "%10s %15s %6s\n", $srv, $_, $h{$srv}{$_} ); } }` [download] `__OUTPUT__ 11BT801 10.197.28.38 1 11BT801 10.197.5.82 2 11BT801 10.200.10.10 1 11BT801 10.200.10.11 1 11BT801 10.200.6.42 2 11BT801 10.200.6.50 1 11BT801 10.200.8.26 2 12GT601 10.100.7.14 1 12GT601 10.100.9.16 2 12GT601 10.160.9.16 1 12GT601 10.180.7.13 1 12GT601 10.197.27.36 1 12GT601 10.197.5.82 2 12GT601 10.200.10.10 1 12GT601 10.200.5.40 2` [download] Boris	[reply] [d/l] [select]
