For those who don't know, Jupyter has a bash kernel: https://github.com/takluyver/bash_kernel And you can run Jupyter notebooks from the CLI with Ploomber: https://github.com/ploomber/ploomber

Thank you! One of my main goals was making data processing in the command-line more accessible and intuitive. If you use a shell you can leverage an extensive array of tools. please take a look at the recipes in the Readme. The shell is many times underrated for data processing! Right now you can use it in Jupiter Notebooks using a shell kernel like: https://github.com/takluyver/bash_kernel On the mid-term, developing a spyql kernel is appealing because of syntax highlighting, code autocompleting, and more. But unless several people show interest on this, I should tackle other features first.

Maybe most useful as resources for further study. Looks like Day 20 covers shell scripting. A few things worth mentioning: You can write tests for shell scripts and write TAP (Test Anything Protocol) -formatted output: https://testanything.org/producers.html#shell Quoting in shell scripts is something to be really careful about: > This and this do different things: # prints a newline echo $(echo "-e a\nb") # prints "-e a\nb" echo "$(echo "-e a\nb")" Shellcheck can identify some of those types of (security) bugs/errors/vulns in shell scripts: https://www.shellcheck.net/ LearnXinYminutes has a good bash reference: https://learnxinyminutes.com/docs/bash/ And an okay Ansible reference, which (like Ops School) we should contribute to: https://learnxinyminutes.com/docs/ansible/ Why do so many pros avoid maintaining shell scripts and w

I think that depends on what you mean; Jupyter lets you run magic[0] commands (run bash commands in subprocesses), and there's also a bash kernel[1]. [0]: https://blog.dominodatalab.com/lesser-known-ways-of-using-no... [1]: https://github.com/takluyver/bash_kernel
