Nushell's data-first approach elevates shell scripting to a new level of clarity and precision.
Traditional shells operate on unstructured text, often requiring brittle parsing. Nushell replaces that with structured data pipelines, enabling consistent, reliable commands that treat output as typed tables, records, and lists. Nushell (often called Nu) is a modern shell designed for working with structured data, built in Rust, and inspired by Unix's pipeline philosophy. Unlike traditional shells that pass text streams, Nushell pipelines pass structured data (tables, records, lists), allowing you to filter, sort, and query information without tedious string parsing. This makes Nu especially powerful for developers and system administrators who frequently work with JSON, YAML, CSV, and other data formats.
Installation and Configuration on Ubuntu
Nushell can be installed on Ubuntu in multiple ways (Apt repository, Snap, or building from source). Here I will focus on the Apt repository method, which is straightforward and keeps Nushell up to date via apt. Alternatively, you can use Snap or Homebrew [1].
To install Nushell securely on Ubuntu using the official Apt repository, start by adding the GPG key that ensures the packages' authenticity. This key is required by the Apt system to verify that downloaded packages come from a trusted source.
