They took the notebook part from IPython and made it language agnostic, this is now Jupyter. You can use Jupyter Notebook together with many languages (Jupyter Kernels) such as R, Julia, Bash and many more in addition to Python.

Ahhh... thank you for explaining.

Including Bash, huh? I remember I used to think that if only a few things were different in ipython I would actually use it as my main terminal window. With Jupyter running bash, are people using it as their main terminal now?

Running a Bash kernel in Jupyter Notebook might be convenient if you are running your Jupyter server on a remote machine. So you don't have to SSH into the server for some quick changes, you can stay in your browser. I haven't used it myself as I only use it locally.

So actually the main reason I'm interested in ipython-style notebooks for my terminal shell needs is the benefit of having... graphs! and pictures! and other graphical things in a terminal shell setting. I'm willing to put up with inconveniences you speak of if I can get the graphical things working well. People have experimented with it, it seems: http://jeroenjanssens.com/2015/02/19/ibash-notebook.html I'll look more into it now.

Only for expository processing, keeping things transparent for people who are not necessarily programmers. Still waiting for spell checking in markdown blocks
