If I had to guess, putting all those shells in the same basket sounds like they're focusing on the universal functionality. Such as pipes and redirection.

- narwally 5y agoThat's what I would imagine. I think think shells other than sh or bash are listed more to make students aware of their existence and to reinforce that, in unix, even something as seemingly fundamental as your shell is a self contained tool that can be swapped out for a variety of alternatives.
- jyounker 5y agoTo extend to your comment, lightly examining a number of shells could also serve a few additional pedagogical functions: * Showing students that there are many shells that they could encounter. * Highlighting the differences. * Showing that there is a long history. * Showing that the history is still alive. * Showing that there is no one right way.
