Ksh (http://www.kornshell.com/ ) is an interactive scripting language suitable for interactive login sessions as well as programming. Source or binary distributions can be obtained from http://www.research.att.com/sw/download/ .
The author, David Korn, has spent a number of years writing UWIN http://www.research.att.com/sw/tools/uwin - a set of Unix like utilities that run on Windows (a concept similar to Cygwin, MKS Toolkit, etc.).
See the author's comments about ksh (and his reference to Tcl) at http://slashdot.org/articles/01/02/06/2030205.shtml , as well as this [L1 ] rave for the shell.
Some of the overlap between Ksh and Tcl can be seen in these packages:
What: tkhistory Where: ftp://ftp.procplace.com/pub/tcl/sorted/packages-7.6/misc/tkhistory-2/tkhistory-2.tar.Z Description: A Tk 3.6 script that visually keeps track of the command history for csh, tcsh, and ksh. Updated: 11/2002 Contact: mailto:[email protected] (Rick McClanahan) What: Tksh Where: http://www.kornshell.com/ http://www.cs.princeton.edu/%7Ejlk/tkshproj/ http://www.research.att.com/sw/tools/reuse/ http://www.gtlinc.com/products/languages/ksh/ksh.html 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.
