Created a script cust.pl to iterate over each hash $ cat cust.pl 
#!/usr/bin/perl
open FILE1, "cust" or die;
my %hash;
my %location;
while (my $line=<FILE1>) {
   chomp($line);
   (my $word1,my $word2, my $word3) = split /\s+/, $line;
   push (@{$hash{$word2}},$word1);
   push (@{$location{$word2}},$word3);
}

for $user (sort keys %hash) {
    print "$user: @{$hash{$user}} \n";
}

for $loc (sort keys %location) {
    print "$loc: @{$location{$loc}} \n";
}
