Free/open source Unix software that pulls info from all my banks/brokers/credit cards? 
Moneydance is a commercial application that is cross-platform. Written in Java, they run and are supported on Windows, Mac and Linux. They integrate with many financial institutions and for those that it cannot, you can import a locally downloaded file. I have used it for several years on my Mac, but have no company affiliation. I'm not sure if by saying "Unix" software you meant FOSS of some kind, but good luck in any case.
