What is the KornShell Language?<\/strong><\/p>\n

The KornShell<\/a> language was designed and developed by David G. Korn at AT&T Bell Laboratories. It is an interactive command language that provides access to the UNIX system and to many other systems, on the many different computers and workstations on which it is implemented.\u00a0<\/p>\n

The KornShell language is also a complete, powerful, high-level programming language for writing applications, often more easily and quickly than with other high-level languages. This makes it especially suitable for prototyping.<\/p>\n

\u00a0There are two other widely used shells, the Bourne shell developed by Steven Bourne at AT&T Bell Laboratories, and the C shell developed by Bill Joy at the University of California. ksh has the best features of both, plus many new features of its own. Thus, ksh can do much to enhance your productivity and the quality of your work, both in interacting with the system, and in programming. ksh programs are easier to write, and are more concise and readable than programs written in a lower-level language such as C.<\/p>\n

The KornShell language uses the same syntax for built-in commands as for non-built-in commands. Therefore, system developers can add new commands “transparently” to the KornShell language; that is, with minimum effort and with no differences visible to users other than faster execution. On systems with dynamic linking, it is possible to add new built-in commands at run time. Novell has extended the new version of ksh to enable X-windows programming for their desktop ksh product, dtksh. dtksh is a standard part of CDE, the Common Desktop Environment defined by COSE (Common Operating System Environment), supported by most major UNIX system hardware vendors. An extended version of ksh that enables Tk programming, called tksh, is available as well.<\/p>\n
