Questions tagged [fish]

The fish shell is an alternate shell, and scripting language, for *nix systems (including macOS). Its claim to fame is being an intuitive, user friendly, and efficient modern shell. Some key examples, per their own website, are enhanced syntax highlighting, completions and autosuggestions (automatically generated from man pages), high performance, and sane scripting.

Fish is a command-line shell designed to be both smart and user-friendly, with auto-suggestions, fully 256 color support, and web-based configuration. Packages for Fish exist for macOS and various flavors of Unix.

Features that differentiate it include rich syntax coloring, auto-completion of commands and arguments, and a high-performance, multithreaded implementation.
