GNU Bourne Again SHell is described as 'Bash is the shell, or command language interpreter, that will appear in the GNU operating system. Bash is an sh-compatible shell that incorporates useful features from the Korn shell (ksh) and C shell (csh). It is intended to conform to the IEEE POSIX P1003.2/ISO 9945' and is a very popular Shell in the os & utilities category. There are more than 25 alternatives to GNU Bourne Again SHell for a variety of platforms, including Linux, Mac, Windows, BSD and Cygwin apps. The best GNU Bourne Again SHell alternative is fish, which is both free and Open Source. Other great apps like GNU Bourne Again SHell are Zsh, Perl, Nu Shell and IPython.

Zsh is a UNIX command interpreter (shell) which of the standard shells most resembles the Korn shell (ksh); its compatibility with the 1988 Korn shell has been gradually increasing. It includes enhancements of many types, notably in the command-line editor, options for...



Perl is a high-level, general-purpose, interpreted, dynamic programming language with over 22 years of development.
This project has reached a minimum-viable product level of quality. While contributors dogfood it as their daily driver, it may be unstable for some commands. Future releases will work fill out missing features and improve stability.



IPython offers a robust architecture for interactive computing, including dynamic shells, a kernel for Jupyter, interactive visualization, GUI toolkit support, and seamless project embeddings. Targeting high efficiency in parallel computing, it supports Python interactions tailored for Jupyter environments.



Xonsh is a Python-powered, cross-platform, Unix-gazing shell language and command prompt. The language is a superset of Python 3.4+ with additional shell primitives that you are used to from Bash and IPython. It works on all major systems including Linux, Mac OSX, and Windows.


The KornShell language was designed and developed by David G. Korn at AT&T Bell Laboratories. It is an interactive command language that provides access to the UNIX system and to many other systems, on the many different computers and workstations on which it is implemented.
Efficient and light, with all required features for a good interactive shell


Elk is an experimental shell language that aims to seamlessly combine the syntax of a shell language like bash with the syntax of a general-purpose language like Python. Bash is great for executing programs and handling files, but can be quite limiting and tedious to use when it...

DASH is a POSIX-compliant implementation of /bin/sh that aims to be as small as possible. It does this without sacrificing speed where possible. In fact, it is significantly faster than bash (the GNU Bourne-Again SHell) for most tasks. DASH stands for Debian Almquist Shell.

Compared to BASH, Zsh has support for many more plugins and addons of the sort. There exists a framework for this very purpose called "Oh-My-Zsh" and it can be used to add things like themes and support for command auto-complete. Zsh is pretty much just BASH but with more features built on top.
