TerminalMaster is an application that's written to be run in Windows Command line which can help people learn how to use Linux in the bash terminal. Not only can it help Linux newbies but also even challenge professionals up to (Linux Professional Institute) level and later serve as a reference.
100 questions are randomly outputted from a larger database each run, the user is presented with three possible answers for each question with only one being the correct one, the user must then choose the correct one by typing the actual correct SYNTAX that would be used in the real Bash terminal, because it's run in a terminal it gives an authentic feel to the real thing and users can remember the syntax overtime and use it within their own Linux installation.
