The Korn shell is an interactive command and scripting language for accessing Unix and other computer systems. As a complete and high-level programming language in itself, it's been a favorite since it was developed in the mid 1980s by David G. Korn at AT&T Bell Laboratories. Knowing how to use it is an essential skill for serious Unix users. Learning the Korn Shell shows you how to use the Korn shell as a user interface and as a programming environment. Learning the Korn Shell is the key to gaining control of the Korn shell and becoming adept at using it as an interactive command and scripting language. Prior programming experience is not required in order to understand the chapters on basic shell programming. Readers will learn how to write many applications more easily and quickly than with other high-level languages. In addition, readers will also learn about Unix utilities and the way the Unix operating system works in general.
This text introduces UNIX to computer science majors and nonmajors, covering basics, simple scriptwriting concepts, and writing shell programs. Material progresses from file systems, shells, filters, and communications, to Korn shell programming and C shell programming.
