'''[http://www.kornshell.com/%|%ksh]''', by [David Korn], is a [Unix Shells%|%Unix Shell] in the [Bourne Shell] family. Versions of ksh are available for various Linux and Unix systems and also for [Microsoft Windows].



** Description **

David Korn has spent a number of years writing UWIN [http://www.research.att.com/sw/tools/uwin%|%UWIN],  a set of Unix like utilities that run on Windows (a concept similar to [Cygwin], MKS Toolkit, etc.).

In [http://slashdot.org/story/01/02/06/2030205/david-korn-tells-all%|%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
[http://web.archive.org/web/20020206073946/http://opensource.devx.com/articles/Laird01/Laird01-1.shtml%|%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
