Nu Shell is described as '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' and is a terminal emulator in the os & utilities category. There are more than 25 alternatives to Nu Shell for a variety of platforms, including Linux, Mac, Windows, BSD and Cygwin apps. The best Nu Shell alternative is PowerShell, which is both free and Open Source. Other great apps like Nu Shell are fish, GNU Bourne Again SHell, Zsh and Elk Shell.
PowerShell (including Windows PowerShell and PowerShell Core) is a task automation and configuration management framework from Microsoft, consisting of a command-line shell and associated scripting language built on the .NET Framework.
Fish is a user-friendly command line shell for UNIX-like operating systems such as Linux
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.
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...
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...
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.
win-bash is a Windows port of the famous GNU bash (see GNU Bash homepage).

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.
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.
Xiki makes the command line friendlier and more powerful. Xiki Shell (xsh) lets you use Xiki from command line, in a way that augments your current favorite shell (bash or zsh).
