Some of my CLI environment set (before I forget)

 First, integrate Zellij into the default shell (https://zellij.dev/documentation/integration) such that as soon as a terminal program (alacritty in my case) is started, Zellij is started.

Second, tweak the Zellij configuration file to make the Nushell the default shell. This way, as soon as Zellij is started, Nu is also started.

Install Starship and integrate it with Nushell (https://starship.rs/guide/). This way, as soon as Nu is started, Starship becomes the default prompt. An example can be found here (https://starship.rs/config/)

Install Yazi and integrate it with Nu, as described here (https://yazi-rs.github.io/docs/quick-start).

The modern CLI stack

Useful article here. The Rust language has really made a difference!

I would also add Amp/Helix editor and Yazi file manager to the list. 

Useful themes for Nushell and Helix editor

 I like the Nord theme for Nushell from this repo and the Sonokai theme for Helix from this repo. 

The Great Linux Distro Dilemma

 This is an interesting review of the current Linux distro world. My current favorite is MX, which is Debian-based, very reliable, and totally no fuss.
