Hello

is there a module, or what is the best way to compare two
hashes and have the differences ?

something like

my %newab = compare(%a,%b)

in %newab i need the values that are in %a but not in %b
and vicevers

my %newba = compare(%b,%a)

thank you

Bye

Check out List::Compare and use it on the keys of your hashes.

See the entry that deal with this problem in perlfaq4: How can I get the
unique keys from two hashes?
