("You are trying to run before you can walk.")
I was unsure whether to post this but decided to so in the end...

Look at your error report(s)...

Your code says "bunny", you say it is "Bunny". Which is it?

More to the point WHERE is it?

Either change the full path to point to it directly or ensure it is in the
your current drawer that this code is looking at...
Also ensure you have the needed permissions to access it.

I also quoted the code as being _old_style_ bash scripting so as to hopefully
give you some insight and to search the WWW for what each line might
be doing and for you to greatly improve on it.

Also it will only work for lines 10 - 19, if you want 20 - pseudo_infinity
then have a go at working it out for yourself; it does get difficult but you'll
learn a lot quickly by mistakes and finding out how to correct them.

Yes it can be improved considerably and there are some seriously clever
guys on here capable of doing it...

There are also different methods too but my method was purely to
demonstrate that it can be done the way I originally stated in my pseudo_code
post...

I, (an amateur), and my professional _cousins_ on here, cannot possibly
be a tutorial class. There are many tutorials to be found on the WWW including
this site to help you and the Admin have prepared all the "man" pages too...

www::search::yahoo

WWW::Search::Yahoo(3pm) 				User Contributed Perl Documentation				   WWW::Search::Yahoo(3pm)

NAME

       WWW::Search::Yahoo - backend for searching www.yahoo.com

SYNOPSIS

	 use WWW::Search;
	 my $oSearch = new WWW::Search('Yahoo');
	 my $sQuery = WWW::Search::escape_query("sushi restaurant Columbus Ohio");
	 $oSearch->native_query($sQuery);
	 while (my $oResult = $oSearch->next_result())
	   print $oResult->url, "
";

DESCRIPTION

       This class is a Yahoo specialization of WWW::Search.  It handles making and interpreting Yahoo searches http://www.yahoo.com.

       This class exports no public interface; all interaction should be done through WWW::Search objects.

NOTES

       The default search is: Yahoo's web-based index (not Directory).

PRIVATE METHODS

       If you just want to write Perl code to search Yahoo, you do NOT need to read any further here.  Instead, just read the WWW::Search
       documentation.

       If you want to write a subclass of this module (e.g. create a backend for another branch of Yahoo) then please read about the private
       methods here:

   gui_query
       Yes, Virginia, we do try to emulate stupid-human queries.

   need_to_delay
       This method tells the WWW::Search controller code whether we need to pause and give the yahoo.com servers a breather.

   user_agent_delay
       This method tells the WWW::Search controller code how many seconds we should pause.

   preprocess_results_page
       Clean up the Yahoo HTML before we attempt to parse it.

   _result_list_tags
       Returns a list, which will be passed as arguments to HTML::Element::look_down() in order to return a list of HTML::Element which contain
       the query results.

   _result_list_items
       Given an HTML::TreeBuilder tree, returns a list of HTML::Element, which contain the query results.

   parse_details
       Given a (portion of an) HTML::TreeBuilder tree and a WWW::SearchResult object, parses one result out of the tree and populates the
       SearchResult.

   _where_to_find_count
       Returns a list, which will be passed as arguments to HTML::Element::look_down() in order to return an HTML::Element which contains the
       approximate result count.

   _string_has_count
       Given a string, returns the approximate result count if that string contains the approximate result count.

   _a_is_next_link
       Given an HTML::Element, returns true if it seems to contain the clickable "next page" widget.

   strip
       Given a string, strips leading and trailing whitespace off of it.
