sudosh is an auditing shell filter and can be used as a login shell. Sudosh records all keystrokes and output and can play back the session as just like a VCR. Sudosh2 is a continuation of the development of sudosh.
Development is no longer done at sourceforge, please see https://github.com/squash/sudosh2 for the current tree.
it's very useful，but there is a question that it only supports English language，not any other language and special character
Well done squash... Let me add a few enhancements with sudosh3.
