1KSH-93 is the most recent version of the KornShell Language described 2in "The KornShell Command and Programming Language," by Morris 3Bolsky and David Korn of AT&T Bell Laboratories. The KornShell is 4a shell programming language, which is upward compatible with "sh" 5(the Bourne Shell), and is intended to conform to the IEEE P1003.2/ISO 69945.2 Shell and Utilities standard. KSH-93 provides an enhanced 7programming environment in addition to the major command-entry 8features of the BSD shell "csh". With KSH-93, medium-sized programming 9tasks can be performed at shell-level without a significant loss 10in performance. In addition, "sh" scripts can be run on KSH-93 11without modification. 12 13WWW: http://www.kornshell.com/ 14
