Hi shankonit,

I hope the comments help you to understand the code. 

#!/usr/bin/perl

use strict;
use warnings;

my $filename = $ARGV[0];
my ($name, $number);

open my $fh, "<", "$filename" or die "$!";
open my $fh2, ">", "list.txt" or die "$!";

while (<$fh>) {                             # read line to variable $_
  chomp;                                    # removes any trailing str
+ing from $_
  if ( /^FN:(.*)/ ) {                       # get the name
    $name = $1;
  } elsif ( /=PREF:(.*)/ ) {                # get the number
    $number = $1;
    printf $fh2 "%15s -> %s\n", $name, $number; #  %d changed to %s in
+ order to keep leading '+'
  }

}

close $fh2 or die "$!";
close $fh or die "$!";
