PowerShell is a shell program developed by Microsoft for task automation and configuration management. As is typical for a shell, it provides a command-line interpreter for interactive use and a script interpreter for automation via a language defined for it. Originally only for Windows, known as Windows PowerShell, it was made open-source and cross-platform on August 18, 2016, with the introduction of PowerShell Core. The former is built on the .NET Framework and the latter on .NET (previously .NET Core).

KornShell (ksh) is a Unix shell which was developed by David Korn at Bell Labs in the early 1980s and announced at USENIX on July 14, 1983. The initial development was based on Bourne shell source code. Other early contributors were Bell Labs developers Mike Veach and Pat Sullivan, who wrote the Emacs and vi-style line editing modes' code, respectively. KornShell is backward-compatible with the Bourne shell and includes many features of the C shell, inspired by the requests of Bell Labs users.

Phosh (portmanteau of phone and shell) is a graphical user interface designed for mobile and touch-based devices initially developed by Purism. The project is maintained and developed by a diverse community, and is the default shell used on several mobile Linux operating systems including PureOS, Mobian and Fedora Phosh. It is also an option on postmarketOS, Manjaro, and openSUSE. Its components follow a six-week release cycle.
