## What it is
fish is a user-friendly, smart interactive command line shell for macOS, Linux, BSD, and Windows (via WSL/Cygwin), written in Rust. It provides syntax highlighting, autosuggestions, and tab completions out of the box with no configuration required, plus a clean, scriptable language.

## Use cases
- replace bash or zsh with a friendlier interactive shell
- get autosuggestions and syntax highlighting in the terminal without configuration
- write shell scripts with a simpler, more consistent syntax
- set up tab completions that work out of the box
- customize my terminal prompt and colors easily
- find a shell that works on macOS, Linux, and BSD

## When to choose
- you want a productive interactive shell that works with zero configuration
- you value autosuggestions, syntax highlighting, and rich completions by default
- you prefer a clean, consistent scripting language over POSIX shell quirks
- you want a mature, actively maintained shell with broad platform support

## When to avoid
- you need strict POSIX/bash compatibility for existing scripts
- your tooling or scripts assume bash/zsh syntax and history substitution
- you must run on a platform without fish packages and cannot build from source

## Facets
- artifact type: application
- maturity: stable
- function: cli, developer-tools, terminal-ui
- domain: developer-tools, operating-systems
- platform: windows, bsd, cross-platform, cli
- tags: shell, fish-shell, autosuggestions, syntax-highlighting, tab-completion, scripting, rust, command-line, linux, macos
