A hash is an array actually in perl.So you may use Array::Diff module on CPAN:

Hi
I have a script which contains 2 hashes of file names as the keys and
md5 sums as the values. I am looking for ideas on fast and efficient
ways to compare the 2 hashes in the manner of the pseudo code below
--
%base_hash
%new_hash
for keys in %new_hash
if key in %new_hash exists in %base_hash
compare values and do something
else
do something else
--
i know there are simple ways to do this. I just wanted ideas on
efficient ways on doing it.
Thank You,
Jim
