Hi,
here are some ideas but i might be totally wrong:
- in the first case, since test.sh has no exec attribute, you get "cannot execute" error
- in the second case, you are telling the binary-executable 'sh' to run commands you pass as parameters (test.sh) ...
You need to strip out read attribute if you dont want the second case happening

ppi::token::attribute5.18
PPI::Token::Attribute(3) User Contributed Perl Documentation PPI::Token::Attribute(3)
NAME
PPI::Token::Attribute - A token for a subroutine attribute
INHERITANCE
PPI::Token::Attribute
isa PPI::Token
isa PPI::Element
DESCRIPTION
In Perl, attributes are a relatively recent addition to the language.
Given the code " sub foo : bar(something) {} ", the "bar(something)" part is the attribute.
A "PPI::Token::Attribute" token represents the entire of the attribute, as the braces and its contents are not parsed into the tree, and
are treated by Perl (and thus by us) as a single string.
METHODS
This class provides some additional methods beyond those provided by its PPI::Token and PPI::Element parent classes.
Got any ideas for methods? Submit a report to rt.cpan.org!
identifier
The "identifier" attribute returns the identifier part of the attribute.
That is, for the attribute "foo(bar)", the "identifier" method would return "foo".
parameters
The "parameters" method returns the parameter strong for the attribute.
That is, for the attribute "foo(bar)", the "parameters" method would return "bar".
Returns the parameters as a string (including the null string '' for the case of an attribute such as "foo()".
Returns "undef" if the attribute does not have parameters.
SUPPORT
See the support section in the main module.
