Re: creating a hash

Hi,

I use to put this hash in a file and get the content using

my $hashref = do $file;

And I want to be able to get the dupplicate keys in order to delete them
manually, without needing to search for each manually and compare it with
every other key from the hash, because if there are only a few keys there is
no problem, but if there are very many... it is.

Thank you.
