I am looking to create interactive workbooks that teach the Gnu/Linux terminal to students. This would be presented in such a way that one half of the screen is an interactive terminal, running the Gnu
bash Unix shell, and the other half of the screen is a workbook, with steps that the student must follow in the included shell. The output from the students' shells would be automatically graded, to ensure that they have correctly followed the steps from the workbook.
So far, I have found two such 'services' http://tuxlab.org/#/ and https://github.com/jakebailey/ua , There are also GitHub classrooms which may fall into this category.
Is anyone else aware of products like this? Preferably open source.
