Official AT&T release of KornShell 93

KSH-93 is the most recent version of the KornShell Language described in “The KornShell Command and Programming Language,” by Morris Bolsky and David Korn of AT&T Bell Laboratories. The KornShell is a shell programming language, which is upward compatible with “sh” the Bourne Shell, and is intended to conform to the IEEE P1003.2/ISO 9945.2 Shell and Utilities standard. KSH-93 provides an enhanced programming environment in addition to the major command-entry features of the BSD shell “csh”. With KSH-93, medium-sized programming tasks can be performed at shell-level without a significant loss in performance. In addition, “sh” scripts can be run on KSH-93 without modification.
