I Was Wrong About Nushell (I Finally Get It Now)

There's a moment when you realize you've been looking at something all wrong.

That happened to me with Nushell. I initially approached it as "just another shell," like Fish or ZSH. Boy, was I missing the point.

We developers spend countless hours juggling data between formats - JSON to YAML, CSV to JSON, parsing API responses, maybe filtering Kubernetes outputs.

Our toolbelt is bursting with specialized tools: jq for JSON, yq for YAML, awk for text processing, and Postman for API testing. Each with its own syntax to remember, each solving just one piece of the puzzle.

​

Here's where Nushell shines

It's not just a shell - it's a unified data processing environment.

Imagine having the power of jq, awk, sed, Postman, and many, MANY other capabilities all in one place, with a consistent syntax. Need to parse a Kubernetes pod list, filter by age, convert it to JSON, and extract nested values? Nushell handles it all in a single pipeline, with helpful error messages that actually make sense.

​

The practical implications are game-changing

Instead of context-switching between tools and remembering different syntaxes, you can process data seamlessly within your shell environment.

Want to explore a complex JSON structure? The explore command gives you an interactive tree view. Need to transform data between formats? Nushell converts between JSON, YAML, and CSV effortlessly. It even provides human-readable timestamps and built-in HTTP request capabilities.

But JSON and YAML are just the start, beyond many other formats, Nushell can explore entire SQLite DBs, run queries, search tables and data. Absolutely mind blowing to those of has who had to rely on so many tools before.

​

Sure, there are rough edges

It's a relatively young project. Many users were frustrated with the scripting language changing often, with breaking changes and modules becoming redundant. For this reason, I'm still not sold on the nu scripting language, but for everything else - very mush so.

For anyone working with data day-to-day (and let's face it, that's most of us), Nushell offers a compelling vision of a more integrated, more intuitive way to work with data at the command line.

Just remember: Nushell isn't trying to replace traditional shells - it's reimagining what a shell can be in our data-driven world. And that's exactly why I was wrong about it the first time around.
