# llLinksetDataDeleteFound

*LSL function*

```lsl
list list llLinksetDataDeleteFound(string pattern, string pass);
```

- `string pattern`: A regular expression (regex) specifying which keys to delete.
- `string pass`: Optional passphrase required to delete matching protected keys.

- Returns: `list`
- Energy: 10

The **`llLinksetDataDeleteFound`** function finds and attempts to delete all keys in the data store that match **pattern**. This function will delete protected key-value pairs only if the matching pass phrase is passed in the **pass** parameter. The function returns a list, the first entry in the list is the number of keys deleted, the second entry in the list is the number of keys that could not be deleted due to a non-matching pass phrase.

If this function successfully deletes any keys from the datastore it will trigger a linkset_data event with the type of LINKSET_DATA_MULTIDELETE, the key name will consist of a comma separated list of the key names removed from the datastore.

Returns a [list](https://wiki.secondlife.com/wiki/list) of the number of keys deleted or skipped.
