thanks Jesus, that was really helpful! However I altered the code alil 
cause ruby rendered an error to me saying that it cant convert Array 
into string (hmmm, dunno if that's normal) for this line(suppose it's 
for the arrays in the hash, exceptions_by_path):
>files = exceptions_by_path.inject(Dir.glob("#{path}/*")) {|result,
ex| result.reject{|x| x =~ Regexp.new(ex)}}

So i decided to name my arays in the hash, file_exception[0], 
file_exception[1] ... and used this instead with an incremental value:

 >>i = 0
>>  src1 = $file_exception[i].inject(Dir.glob(src)) {|result, >>ex|result.reject{|x| x =~ Regexp.new(ex)}}
>> i = 1 + i

But i had the problem of accidentally keyin in the a wrong path name and 
nothing was shown for the 2nd source path.(Only after troubleshooting 
for 1 whole hr did i realise) So is there any way where by we can have a 
condition something like, if result == nil puts "wrong pathname"(just an 
idea, cos i tried and it doesnt work)

And btw dont get me wrong, Struct is sweet too, just that i didnt want 
to have a fixed number of exceptions for each path. ;)

Thanks again.
