nushell

Modern shell that treats data as structured information

TLDR

Start the shell

$ nu

Run a command string and exit

$ nu -c "[command]"

Run a script file

$ nu [path/to/script.nu]

Start as a login shell

$ nu --login

Start without loading config files

$ nu -n

List files as structured data (inside nu)

$ ls | where size > 1mb | sort-by modified

Convert JSON to a table (inside nu)

$ open [data.json] | select name age | sort-by age

nushell (command: nu) is a modern shell that treats data as structured information rather than plain text. It brings spreadsheet-like data manipulation to the command line with built-in support for JSON, CSV, YAML, SQLite, Excel, and more.Nu pipelines use structured data so you can safely select, filter, and sort the same way every time. It draws inspiration from PowerShell, functional programming languages, and modern CLI tools. It is cross-platform with first-class support for Windows, macOS, and Linux.
