The goal of this project is to take the Unix philosophy of shells, where pipes connect simple commands together, and bring it to the modern style of development.

Nu takes cues from a lot of familiar territory: traditional shells like bash, advanced shells like PowerShell, functional programming, systems programming, and more. But rather than trying to be the jack of all trades, Nu focuses its energy on doing a few things well:

Create a flexible cross-platform shell with a modern feel
Allow you to mix and match commandline applications with a shell that understands the structure of your data
Have the level of UX polish that modern CLI apps provide
