The New KornShell—ksh93

The KornShell, written by David Korn at Bell Telephone Laboratories, combined the best features of both of these shells, and added the ability to edit and reenter the current and previous commands using the same keystrokes as either the vi or the Emacs editor as the user desired.

ksh93, the latest major revision of the KornShell language, provides an alternative to Tcl and Perl. As a programming language, it has comparable speed and functionality to each of these languages. Like Tcl, it is extensible and embeddable with a C language application programming interface. The New KornShell, ksh93, and the Tksh products are available from Global Technologies, Ltd., Inc., 5 West Ave, Old Bridge, NJ 908-251-2840.
