I am new to perl scripting. I have 2 new input files, file1 and file2. I have to retrieve second field of each record from first file and check if it is existing in second file, file2. I have read file2 contents and stored it in an array. Please find my file2(npn.txt) contents below: 

11111111
10001781
11111222

File1 contents: 
abc,,,, 
abc,10001781,,,
abc,10001782,,, 
abd,10001783,,,

[download]

Based on above files, what my record should contain: 

abc,,,, 
abc,10001782,,, 
abd,10001783,,,

[download]
But it prints: 
abc,10001781,,, 
abc,10001782,,, 
abd,10001783,,,

Can anyone please guide me what is the bug in this. Please find my code snippet below: 

...
open (info, "<npn.txt");
chomp (@contents = (<info>));
close info;


$record = $_."~";
@flds = split(/\,/, $record);

if (grep !/^$flds[1]/, @contents) {
 
  print $record;
}
