Re^2: Unique list of hashes

in reply to Re: Unique list of hashes
in thread Unique list of hashes

Make a key out of combined values to search for uniqueness ... @uniq = grep !$seen{ join '' , sort values %{ $_ } }++, @list;

So these are all the same?

my @list = (
    { foo=>'bar', quz=>'baz' },
    { abc=>'bar', def=>'baz' },
    { ijk=>'ba', xyz=>'rbaz' },
    { r=>'ba', s=>'rba', t=>'z' },
    { x=>'barbaz' },
);

Using a delimiter that cannot appear in the values would be useful... like a pipe or such.	[reply]

Nope, not all are same as you already know. hdb has already given slightly complicated method to satisfy your situation.	[reply]
