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' }, );` [download]	[reply] [d/l] [select]

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]
