It's possible the tool is useless and a consequence of not reading the manual, but it could just be the tool is nice but the examples are too simplistic.

In any case, toxicity aside, publishing a command line project and having someone dismiss the examples with shell oneliners is also a valuable lesson, and I don't think it will make him a worse developer.

that's what I also thought when I saw the pull request, that it could be a useful lecture.

But again the usefulness of the final tool should not compromise appreciation of effort and learning.

Unless the tool targets, claims or pretends to be the best, final and universal solution to such problem.

I believe it isn't, I will still fall back to my bash memories, I will not need, install and use this tool, I will not need, install or use custom shells. The effort wasted in re-aligning my brain to a tool change would superseed instantly the few second effort needed to reach the needed bash one-liner.

Also, didn't you also feel good and amazed when completing a very long and nested working one-liner? wasn't that orgasmic? :D
