MirBSD Korn Shell (mksh) review
A focused Korn-compatible shell for interactive work and scripting across Unix-like systems.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
MirBSD Korn Shell (mksh) is a free, open-source command-line shell maintained by the MirOS Project. It is intended for people who want a Korn-compatible environment for interactive command-line work or shell scripting, particularly across Linux, macOS, and Android. Its fit spans individual use through enterprise environments, but its core purpose remains the shell itself rather than a wider development suite.
The main distinction is compatibility and portability. mksh is described as an enhanced version of the Public Domain Korn shell, with KornShell (ksh) as its scripting language. The project provides source code for building it, and it is included in Android platform sources, giving it a notable place in Android-oriented environments as well as Unix-like systems. That makes it relevant where existing shell scripts or workflows call for Korn compatibility. It is distributed under the MirOS Licence.
Deployment is self-hosted, and the published feature set centers on the shell, source distribution, interactive use, and scripting. That focused scope suits people comfortable building or obtaining shell software through their environment; it may be a less direct choice for someone seeking a graphical interface or a broader set of packaged developer tools. Choose mksh when Korn compatibility and use on Android or Unix-like systems are priorities. Consider another shell if your needs depend on capabilities beyond the functions described here.
