Corona688's answer is pretty right, but don't forget to chomp!
chomp removes the newline character from the end of line.
Code:
chomp($LINE);

the line input operator includes the newline at the
end of the input. There are lots of ways to remove that newline, but
the best way is to use the "chomp" function

MooseX::AttributeHelpers::Trait::String(3pm)		User Contributed Perl Documentation	      MooseX::AttributeHelpers::Trait::String(3pm)

NAME

       MooseX::AttributeHelpers::String - simple string attribute

SYNOPSIS

	 package MyHomePage;
	 use Moose;
	 use MooseX::AttributeHelpers;

	 has 'text' => (
	     metaclass => 'String',
	     is        => 'rw',
	     isa       => 'Str',
	     default   => sub { '' },
	     provides  => {
		 append => "add_text",
		 replace => "replace_text",
	     }
	 );

	 my $page = MyHomePage->new();
	 $page->add_text("foo"); # same as $page->text($page->text . "foo");

DESCRIPTION

       This module provides a simple string attribute, to which mutating string operations can be applied more easily (no need to make an lvalue
       attribute metaclass or use temporary variables). Additional methods are provided for completion.

       If your attribute definition does not include any of is, isa, default or provides but does use the "String" metaclass, then this module
       applies defaults as in the "SYNOPSIS" above. This allows for a very basic counter definition:

	 has 'foo' => (metaclass => 'String');
	 $obj->append_foo;

METHODS

       meta
       method_provider
       has_method_provider
       helper_type
       process_options_for_provides
	   Run before its superclass method.

       check_provides_values
	   Run after its superclass method.

PROVIDED METHODS

       It is important to note that all those methods do in place modification of the value stored in the attribute.

       inc Increments the value stored in this slot using the magical string autoincrement operator. Note that Perl doesn't provide analogeous
	   behavior in "--", so "dec" is not available.

       append $string
	   Append a string, like ".=".

       prepend $string
	   Prepend a string.

       replace $pattern $replacement
	   Performs a regexp substitution ("s" in perlop). There is no way to provide the "g" flag, but code references will be accepted for the
	   replacement, causing the regex to be modified with a single "e". "/smxi" can be applied using the "qr" operator.

       match $pattern
	   Like replace but without the replacement. Provided mostly for completeness.

       "chop"
	   "chop" in perlfunc

       "chomp"
	   "chomp" in perlfunc

       "clear"
	   Sets the string to the empty string (not the value passed to "default").

BUGS

       All complex software has bugs lurking in it, and this module is no exception. If you find a bug please either email me, or add the bug to
       cpan-RT.
