Subject: comparing hash values
I
I am trying to populate a hash with key/value pairs, basically the file name and its
dates. I am extracting part of the file name to use as the key. Some of the keys will
be the same. I want to put a new value in only if its newer than the value currently
stored.
My problem is, how do I know
