I'm not sure if you just want to check if the username exists, or get the
values associated with it. Also, it seems like you won't know the keys of
the nested hash. If that's the case the following checks to see if the key
$user exists and then gets the values in the associated hash.
if (defined(%{$users{$user}})){
while((my $key, my $value)=each(%{$users{$user}})){
print "$key: $value\n";
}
}
else {
print "No match for $user.";
}
