description nushell Overview

nushell is a modern shell designed for data-oriented workflows and powerful scripting. Built with Rust, it emphasizes data structures and pipelines, allowing users to manipulate data directly within the shell. Its syntax is inspired by functional programming paradigms, offering a more expressive and concise way to write scripts. nushell aims to bridge the gap between command-line tools and programming languages, providing a unified environment for data manipulation and automation.

help nushell FAQ

What makes nushell different from Bash or PowerShell?

nushell treats command output as structured data instead of plain text whenever possible. That lets users filter, sort, and select table columns directly, while Bash relies heavily on text tools and PowerShell uses .NET-based objects.

What language is nushell written in?

nushell is written in Rust and is available for major desktop operating systems. Its commands use a shell syntax designed around structured pipelines rather than traditional POSIX text streams.

Can nushell work with CSV and JSON files?

Yes, Nushell includes data-oriented commands for working with formats such as CSV, JSON, and TOML. A pipeline can load structured data, select fields, filter rows, and export the result without manually splitting text.

Can existing Bash scripts run unchanged in nushell?

No, nushell has different syntax, variables, quoting rules, and pipeline behavior, so Bash scripts usually need adaptation. You can still launch external commands and use Bash separately when a legacy script depends on POSIX shell behavior.
