IPython. Seems to work for simple stuff like `ls blah`, but I'm not aware how far this stretches, and is probably not super safe to use.
EDIT: Seems I've only tried too basic things - it works thanks to %automagic, and seemingly %man is a thing. Other option is to use %%sh or %%bash, but that's a bit verbose.
