Really, there are a number of different ways to accomplish this task. Perhaps one of the most straight foward methods might be (un-tested): 

#!/usr/bin/perl

use strict;
use warnings;

open FILE_1, 'file.1' || die 'ERROR:\t$!\n";
open FILE_2, 'file.2' || die 'ERROR:\t$!\n";

while ( my $line = <FILE_2> ) {
  my ( $filename, $accounts, @nonrelevant ) = split( /\t/, $line );
  next if ( $accounts exists( @{[<FILE>]} ) );

  print "$accounts:\t$filename\n";
}

close FILE_1;
close FILE_2;

This is assuming that 'file 2' is tab separated, the layout of the file is as explained, and that I do not know the names or locations of the files.

Otherwise, this (or something very similar) should search the first file for the account you are working with in the second file, and only print out the account and file name of the accounts that are not within the first file.

Good Luck!
