overview
KornShell, ksh93
history
KornShell 93 is the KSH-93 line of David Korn's KornShell language, carried forward as a Unix shell, scripting language, and POSIX-oriented command environment. The Homebrew ksh93 package points at the community 93u+m continuation, which is based on AT&T's last stable 93u+ release dated 2012-08-01.
The ksh93 README republishes the 1993 AT&T description of KSH-93 as the version of the KornShell language described in The KornShell Command and Programming Language, compatible with Bourne shell scripts and intended to conform to the IEEE POSIX shell and utilities standard. That lineage made ksh93 both a production Unix shell and a language-runtime package with features beyond traditional sh.
The ksh93/ksh project began as a community reboot from AT&T AST sources after an attempted 2017-2020 ksh2020 refactoring effort was abandoned. The maintainers chose the older stable 93u+ code as the base and backported fixes from ksh2020, distribution patches from OpenSUSE, Red Hat, and Solaris, and new community fixes.
KornShell has long been part of commercial and open Unix culture, especially where POSIX shell compatibility, stronger scripting features, and historical vendor scripts mattered. The 93u+m README notes that Debian and Slackware began packaging 93u+m as their default ksh93 version in late 2021, marking the community fork's transition from preservation project to distro-consumed shell.
Users run ksh93 as an interactive shell, as a /bin/sh-compatible scripting engine, and through related tools such as rksh and shcomp. It matters most where shell-language compatibility, arithmetic and scripting features, or existing ksh scripts are more important than using bash or zsh.
ksh93 is package-nerd significant because it is not just another shell binary: it is a maintained survival path for AT&T AST code, legacy KornShell scripts, POSIX conformance work, and old Unix assumptions that still surface in modern distributions.
