Fish Shell

Fish is a smart and user-friendly command line shell for macOS, Linux, and the rest of the family. Fish includes features like syntax highlighting, autosuggest-as-you-type, and fancy tab completions that just work, with no configuration required.

Fish has “search as you type” automatic suggestions based on history and current directory. This is essentially like Bash’s Ctrl+R history search, but because it is always on instead of being a separate mode, the user gets continuous feedback while writing the command line, and can select suggestions with the arrow keys, or as in Bash, press Tab ↹ for a tab completion instead.

Tab-completion is feature-rich, expanding file paths (with wildcards and brace expansion), variables, and many command specific completions. Command-specific completions, including options with descriptions, can to some extent be generated from the commands’ manpages.
