1 KSH-93 is the most recent version of the KornShell Language described
2 in "The KornShell Command and Programming Language," by Morris
3 Bolsky and David Korn of AT&T Bell Laboratories. The KornShell is
4 a shell programming language, which is upward compatible with "sh"
5 (the Bourne Shell), and is intended to conform to the IEEE P1003.2/ISO
6 9945.2 Shell and Utilities standard. KSH-93 provides an enhanced
7 programming environment in addition to the major command-entry
8 features of the BSD shell "csh". With KSH-93, medium-sized programming
9 tasks can be performed at shell-level without a significant loss
10 in performance. In addition, "sh" scripts can be run on KSH-93
