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.
At the end of the day, fish is still a language for the shell, hence not necesaarily readable if you don’t pay attention to that kind of thing. The difference is that the special-character count drops by like 80% and it is actually possible to write something readable. Imo this is next to impossible in bash. Also their builtins are pure love. The
stringcommand covers pretty much anything you might ever wish to do with any kind of string.
