It auto-complete the commands that are pretty cool. Fish is fully scriptable, and its syntax is simple, clean and consistent. Fish is a fast, the auto-completion is amazingly helpful and it's intuitive use without too much configuration.

• Fish suggest commands as you type, based on history and completion, just like a web browser. Complete the autosuggestion by hitting the right arrow key.
