As its name suggests, the friendly interactive shell (also known as fish) is a user-friendly, free and open source interactive UNIX shell specifically designed to be used for its interactiveness and discoverability features. It’s a drop-in replacement for Bash (Bourne shell).

fish’s main goal is to offer a rich set of powerful functionality, including tab-completion, a discoverable and extensive help system, tab-completion of strings with wildcards, and many other attractive functionality that we’ve listed below at a glance.

Features at a glance

The friendly interactive shell is easy to use, search, remember, and discover. It includes a special help command, which allows users to access all of its documentation, syntax highlighting support, smart terminal handling, and support for the internal clipboard function of a GNU/Linux system.

The program is written entirely in the C++ programming language and can be deployed on any distributions of Linux, as well as on other UNIX-like operating systems, such as Mac OS X, BSD or Solaris.

Getting started with fish

Installing the fish-shell on your GNU/Linux distribution proves to be an easy task even for beginners, as you will only have to download the latest version of the application from Softpedia, save the archive on your PC and extract its contents using your favorite archive manager.

Then, open a Terminal app and go to the location of the extracted archive files (e.g. cd /home/softpedia/fish-2.1.1), where you must run the ‘./configure && make’ command to configure and compile the program, followed by the ‘make install’ command to install it.
