Issue renaming a file

I am having an issue renaming a file with the File::Find module.

my @initial_directory = ("/Users/test/Development/sandbox/file_strip_example/files");

find (\&wanted, @initial_directory);

sub wanted {
return unless /\s$/;

my $new_name = $File::Find::name;
$new_name =~ s/ +$//; # Remove trailing spaces in the filename
chomp $new_name;

print "Renaming >>$File::Find::name<< to >>$new_name<<\n";
rename $File::Find::name, $new_name;

In that location there is a file named: testFile  with a space at the end of the name. For some reason i am unable to strip the space at the end of the file.

Hi skingsbu1,

> In that location there is a file named: testFile  with a space at the end of the name. For some reason i am unable to strip the space at the end of the file.

A few questions for you.

Q1. In the above paragraph, do you mean that this failed?:
    $new_name =~ s/ +$//; # Remove trailing spaces in the filename

Q2. If so, does this work?:
    $new_name =~ s/\s+$//; # Remove trailing whitespace from the filename

I'm wondering whether the "space" is actually some other kind of whitespace like a "tab".  The above command should also remove any new-line/carriage-return characters making the chomp redundant.

Q3. What is the output of the following command, before and after the above change?
    print "Renaming >>$File::Find::name<< to >>$new_name<<\n";
