I had to check but wow, you're right. Next time someone says OSX is just like any other UNIX underneath I can give them that.


This is why it's always a good idea to say what your system is in your first post, so we don't have to play the strange combination of 20-questions and pin-the-tail-on-the-donkey that is finding answers to questions here. Smilie

I'll try -n and see if that resolves the error.
Be sure to quote the string. No quotes means [ -n $STUFF ] becomes [ -n ] which is a syntax error. [ -n "$STUFF" ] becomes [ -n "" ] which is okay.

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
