Wildcard Characters Specified for Delete

You can use the wildcards as follows:

Wildcard Description
* Search for any number of characters at this point in the string. For example, if you want to delete all points that start with M and end with X, enter M*X in the <point_id> field.
? Search for any character in this place in the string. For example, if you want to delete all points whose names are three characters long and whose first character is M and third character is X, enter M?X in the <point_id> field.
Note: There are no implied wildcards. If you do not include or terminate your Point ID string with an asterisk, only those Point Ids that match your request exactly will be deleted.

Wild cards do not work with the -sp option.
