The code should work fine with the changes you mention.
You say it doesn't work, could you explain what exactly is happening?

Are you sure you that want to understand every part (it seams you prefer to avoid Perl)?
Quote:
You can try to write a shell script for this task if you don't want to use Perl (?).

ppi::token::quote
PPI::Token::Quote(3) User Contributed Perl Documentation PPI::Token::Quote(3) NAME
PPI::Token::Quote - String quote abstract base class INHERITANCE
PPI::Token::Quote isa PPI::Token isa PPI::Element DESCRIPTION
The "PPI::Token::Quote" class is never instantiated, and simply provides a common abstract base class for the four quote classes. In PPI, a "quote" is limited to only the quote-like things that themselves directly represent a string. (although this includes double quotes with interpolated elements inside them). The subclasses of "PPI::Token::Quote" are: '' - PPI::Token::Quote::Single "q{}" - PPI::Token::Quote::Literal "" - PPI::Token::Quote::Double "qq{}" - PPI::Token::Quote::Interpolate The names are hopefully obvious enough not to have to explain what each class is here. See their respective pages for more details. Please note that although the here-doc does represent a literal string, it is such a nasty piece of work that in PPI it is given the honor of its own token class (PPI::Token::HereDoc). METHODS
string The "string" method is provided by all four ::Quote classes. It won't get you the actual literal Perl value, but it will strip off the wrapping of the quotes. # The following all return foo from the ->string method 'foo' "foo" q{foo} qq <foo> literal The "literal" method is provided by ::Quote:Literal and ::Quote::Single. This returns the value of the string as Perl sees it: without the quote marks and with "\" and "'" resolved to "" and "'". The "literal" method is not implemented by ::Quote::Double or ::Quote::Interpolate yet. SUPPORT
