Fish shell, a popular user-friendly command-line shell, has announced version 4.2, a new release that builds on the 4.0 series. Among the most visible improvements is an upgrade to history-based autosuggestions, which now properly handle multi-line commands.
Fish 4.2 also improves how prompts are managed: transient prompts that contain more lines than the final one are now cleared properly, preventing visual clutter on screen. Similarly, the shell now hides parts of a multi-line prompt that have scrolled out of view, eliminating duplicated lines after repainting.
it really is fantastic out of the box. When I switched to NixOS I had decided to stay on zsh/ohmyzsh and it was an absolute slog. it was so slow and didn’t mesh well with the zsh plugins. Someone suggested I try Fish instead as it pretty much could do what Zsh does with plugins but right out of the box. Fish was much faster and indeed could do everything that I had configured zsh to do but I didn’t have to configure Fish at all. It’s great, I’ll never use another shell.
