Install FISH command line shell on Linux Ubuntu 15.04, Ubuntu 14.04 and Derivatives. FISH (friendly interactive shell) is a command line shell for interactive users.
A shell is a user interface to access operating system. Shells use either a command-line interface (CLI) or graphical user interface (GUI).
FISH Features:
- Autosuggestions – FISH suggests commands as you type based on history and completions, just like a web browser. Watch out, Netscape Navigator 4.0!
- Glorious VGA Color – FISH natively supports term256, the state of the art in terminal technology. You’ll have an astonishing 256 colors available for use!
- Sane Scripting – FISH is fully scriptable, and its syntax is simple, clean, and consistent. You’ll never write esac again.
- Web Based configuration – For those lucky few with a graphical computer, you can set your colors and view functions, variables, and history all from a web page.
- Man Page Completions – Other shells support programmable completions, but only FISH generates them automatically by parsing your installed man pages.
Works Out Of The Box – FISH will delight you with features like tab completions and syntax highlighting that just work, with nothing new to learn or configure.
