title: FilterOperator: suffix
type: text/vnd.tiddlywiki
The ''suffix'' filter operator returns the titles in the current list that end with a specified suffix. If the ''suffix'' operator is preceded by `!` then it returns the titles that do not end with the specified suffix.
For example:
|!Filter String |!Description |
|`[tag[task]!suffix[hidden]]` |Returns tiddlers tagged `task` whose titles do not end with `hidden` |
|`[suffix[.jpg]]` |Returns tiddlers whose titles end with `.jpg` |
