How to list duplicate nodes based on title with views I'm trying to list all duplicate nodes based on node title with views.

In views aggregation settings it's said that:


  If enabled, some fields may become unavailable. All fields that are
  selected for grouping will be collapsed to one record per distinct
  value. Other fields which are selected for aggregation will have the
  function run on them. For example, you can group nodes on title and
  count the number of nids in order to get a list of duplicate titles.


I enabled aggregation and added a node content title filter (aggregation: count) to count nodes and list if a title has more than one node (count:  Is greater than 1). But it doesn't work for me, it lists nodes with unique titles and duplicate titles (I mean no affect).

How can I list all nodes with duplicate titles by using views?
The filter should be on content:nid. Set it to aggregate on COUNT, and 'Is greater than' value 1.

Then check all of your fields that you have added. None of the fields for nodes with the same title should output a different value. Title for instance, can be unique, depending on how you output it. If you for instance output it as a link (the default), then for each title that is the same, but that belongs to another node, the link is unique, therefore you view won't perform the way you want it to. So deselect 'Link this field to the original piece of content' and it should work.
