Version 8 of ksh

Updated 2015-01-01 05:44:02 by pooryorick

ksh , by David Korn, is a Unix Shell in the Bourne Shell family. Versions of ksh are available for various Linux and Unix systems and also for Microsoft Windows.


David Korn has spent a number of years writing UWIN UWIN , a set of Unix like utilities that run on Windows (a concept similar to Cygwin, MKS Toolkit, etc.).

In David Korn Tells All , 2001-02-07, David Korn states that ksh93 should be compared to Tcl, in the sense that it is implemented as a reusable library with a C language API, and points to dtksh and tksh as an example of the embedability/extensibility of ksh93. In Playing the MacOS Shell Game , Cameron Laird argues in favour of ksh over tcsh.

ksh93 aims for compatibility with the Shell Language Standard part of POSIX, and can therefore be used as a Bourne Shell replacement.

Some of the overlap between Ksh and Tcl can be seen in these packages:

 What: tkhistory
 Description: A Tk 3.6 script that visually keeps track of the
        command history for csh, tcsh, and ksh.

 What: Tksh
 Description: Tksh is an implementation of the Tcl C library written on
        top of ksh93. Tksh emulates the
        behavior of Tcl by using the API that is provided for extending ksh93.
        This allows Tcl libraries such as Tk to run on top of ksh93
        unchanged, making it possible to use shell scripts in place of Tcl
        scripts. ksh93 is well suited for use with Tk because it is backward
        compatible with sh, making it both easy to learn and easy to extend
        existing scripts to provide a graphical user interface. Tksh
        allows Tcl scripts to run without modification using the
                ksh93 internals.
        The latest tksh works with Tcl 7.6.  The author is no longer
        working on this application.
