Shell Programming in Unix, Linux and OS X is a thoroughly updated revision of Kochan and Wood's classic Unix Shell Programming tutorial. Following the methodology of the original text, the book focuses on the POSIX standard shell, and teaches you how to develop programs in this useful programming environment, taking full advantage of the underlying power of Unix and Unix-like operating systems. After a quick review of Unix utilities, the book's authors take you step-by-step through the process of building shell scripts, debugging them, and understanding how they work within the shell's environment. All major features of the shell are covered, and the large number of practical examples make it easy for you to build shell scripts for your particular applications. The book also describes the major features of the Korn and Bash shells. Learn how to...

""Programming in C, Fourth Edition"" is a newly revised and updated edition of Steven Kochan's classic C programming tutorial: a book that has helped thousands of students master C over the past 25+ years. This edition fully reflects current developments in C programming, including the latest version (C11). Crafted to help students master C regardless of their intended platform or applications, it includes substantial new coverage of mobile and gaming applications where C's elegance and speed make it indispensable. Kochan brings a unique ability to connect with readers, understand their needs, and explain a language with exceptional clarity and relevance. Here, he begins with the fundamentals, then covers every facet of C programming: variables, data types, arithmetic expressions, program looping, making decisions, arrays, functions, structures, strings, pointers, operations on bits, preprocessors, I/O, and more. You'll find up-to-date chapters on writing larger programs; debugging, and object-oriented fundamentals. Appendices include a complete language summary; an introduction to the current Standard C Library; coverage of compiling and running programs using gcc; and avoiding common coding mistakes. This edition contains improved examples and explanations, as well as new material on C-based object languages such as Objective-C (reflecting Kochan's unique experience as author of "Programming in Objective-C 2.0," today's leading Objective-C tutorial).
