Fish is a friendly command line shell for Ubuntu/Linux, Mac or any other operating system from the *nix family. If you use bash (the default shell in Ubuntu) often, then you may want to give it a try. It has lots of smart features you may find productive.
Features
- Autosuggestions – It suggests commands when you type, based on history and it’ll often save you some time with the commands you type more often.
- Scripting – Similar to bash but the syntax is much simple, clean and consistent.
- term256 – it supports 256 colors.
- Sane defaults – Most of the features will work just fine without any additional configurations.
