Korn shell

The Korn shell (ksh) is a Unix shell developed by David Korn. It is compatible with the Bourne shell and includes many features of the C shell as well, such as a command history. For interactive use it provides the ability to edit the command line in a WYSIWYG fashion patterned after the vi and emacs editors. It also includes built-in arithmetic evaluation and advanced scripting functions similar to those used in more powerful programming languages such as awk, sed, and perl.

SKsh is an AmigaDOS-specific version and pdksh is a free Unix version.
