There's no actual software product called "UNIX" that you can go and get, then install on a computer. There hasn't been for a very long time. UNIX is a blueprint now, a standard around which operating systems are designed.
UNIX-based systems often have a variety of shells to choose from anyway, varying in features, so we also need to know which one you're using.
Try uname and uname -a to find out what you're actually running.
Try echo $SHELL to find out what your shell actually is.
