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
