May as well flog the little zsh thing I wrote: https://github.com/ckp95/fwf/ https://github.com/ckp95/fwf/ fwf -- "Filter With Feedback". It lets you write sed/awk/jq/grep etc things interactively. You type in a UNIX filter, and on every keystroke it renders the result in a column on the right, which you can compare to the original on the left (watch the video demonstration on the link if that description is confusing). I wrote it to make the feedback loop for text-processing as quick as possible. I use it all the time now. It makes the "activation energy" for writing shell pipelines a lot lower, if that makes sense.
