Learning the Korn Shell
Publisher: O'Reilly Media
Final Release Date: January 1993
Pages: 360

This Nutshell Handbook® is a thorough introduction to the Korn shell, both as a user interface and as a programming language.

The Korn shell, like the C and Bourne shells, is a program that interprets UNIX commands. It has many features that aren't found in other shells, including command history (the ability to recall and edit previous commands). The Korn shell is also faster; several of its features allow you to write programs that execute more quickly than their Bourne or C shell equivalents.

This book provides a clear and concise explanation of the Korn shell's features. It explains ksh string operations, co-processes, signals and signal handling, and one of the worst "dark corners" of shell programming: command-line interpretation. It does this by introducing simple real-life examples and then adding options and complexity in later chapters, illustrating the way real-world script development generally proceeds. An additional (and unique) programming aid, a Korn shell debugger (kshdb), is also included.

Learning the Korn Shell is an ideal resource for many UNIX users and programmers, including software developers who want to "prototype" their designs, system administrators who want to write tools for their own use, and even novices who just want to use some of ksh's more advanced interactive features.

Learning the Korn Shell Review

By Adam Gordon

from Undisclosed

Comments about O'Reilly Media Learning the Korn Shell:

The only O'Reilly book I own that I've actually read cover-to-cover. The examples were appropriate, informative, and well-explained. This book is a must have for anyone using UNIX. An example or two covering building variables on the fly to circumvent Korn's lack of structures would have been helpful.

This book remained open on my desk for a solid summer while I was getting my feet wet with system administration. It is a great resource that I frequently refer back to.

I use this book as a reference all the time. I'd like it updated for the latest version of the Korn Shell, ksh93.

Learning the Korn Shell Review

By Doug

from Undisclosed

Comments about O'Reilly Media Learning the Korn Shell:

I needed to read a book about Korn Shell fast, and I found what I needed in this book. The format of the book is a little confusing, and certain concepts are not explained as clearly as I would like, but on the other hand I have now been able to write my own Korn shell scripts and configure my own Korn Shell environment without much difficulty. All, in all, I enjoyed this book much.
