The KornShell Command and Programming Language

The KornShell 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(R) system and to many other systems, on the many different computers and terminals on which it is implemented. It is also a complete,powerful, high-level programming language with which you can write applications, often more easily and quickly than with other high-level languages. This book is the specification and reference handbook for ksh, the program that implements the KornShell language.
