[FILTER]
You may specify any of these filters. Filters can be negated using the
--no-... versions, e.g., --no-tasks. Multiple filters are applied in
conjuction. By default, the filter --no-completed is used. Note that
--no-completed is not the same as --open, and similarly, --no-open is not the
same as --completed.
--tasks Show tasks only
--notes Show notes only
--journal Show jounral only
--completed Show completed tasks only
--open Show open tasks only
--filter <query> Specify custom query"
