description: Render tiddlers matching a filter to a specified ContentType

(Note: The `--rendertiddlers` command is deprecated in favour of the new, more flexible `--render` command)

Render a set of tiddlers matching a filter to separate files of a specified ContentType (defaults to `text/html`) and extension (defaults to `.html`).

```
--rendertiddlers '<filter>' <template> <pathname> [<type>] [<extension>] ["noclean"]
```

For example:

```
--rendertiddlers '[!is[system]]' $:/core/templates/static.tiddler.html ./static text/plain
```

By default, the pathname is resolved relative to the `output` subdirectory of the edition directory. The `--output` command can be used to direct output to a different directory.

Any files in the target directory are deleted unless the ''noclean'' flag is specified. The target directory is recursively created if it is missing.
