Shell Programming in Unix, Linux and OS X (Developer's Library)

<p style="margin:0px;"> <i>Shell Programming in Unix, Linux and OS X </i>is a thoroughly updated revision of Kochan and Wood’s classic <i>Unix Shell Programming </i>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.</p> <p style="margin:0px;"> <br> </p> <p style="margin:0px;">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.</p> <p style="margin:0px;"> <br> </p> <p style="margin:0px;">Learn how to…</p> <ul> <li> <div style="margin: 0px;">Take advantage of the many utilities provided in the Unix system</div> </li> <li> <div style="margin: 0px;">Write powerful shell scripts </div> </li> <li> <div style="margin: 0px;">Use the shell’s built-in decision-making and looping constructs</div> </li> <li> <div style="margin: 0px;">Use the shell’s powerful quoting mechanisms</div> </li> <li> <div style="margin: 0px;">Make the most of the shell’s built-in history and command editing capabilities</div> </li> <li> <div style="margin: 0px;">Use regular expressions with Unix commands</div> </li> <li> <div style="margin: 0px;">Take advantage of the special features of the Korn and Bash shells</div> </li> <li> <div style="margin: 0px;">Identify the major differences between versions of the shell language</div> </li> <li> <div style="margin: 0px;">Customize the way your Unix system responds to you</div> </li> <li> <div style="margin: 0px;">Set up your shell environment</div> </li> <li> <div style="margin: 0px;">Make use of functions</div> </li> <li> <div style="margin: 0px;">Debug scripts</div> </li> </ul> <p style="margin:0px;"> <b>Contents at a Glance</b> </p> <p style="margin:0px;"> <br> </p> <p style="margin:0px;">1  A Quick Review of the Basics</p> <p style="margin:0px;">2  What Is the Shell?</p> <p style="margin:0px;">3  Tools of the Trade</p> <p style="margin:0px;">4  And Away We Go</p> <p style="margin:0px;">5  Can I Quote You on That?</p> <p style="margin:0px;">6  Passing Arguments</p> <p style="margin:0px;">7  Decisions, Decisions</p> <p style="margin:0px;">8  ‘Round and ‘Round She Goes</p> <p style="margin:0px;">9  Reading and Printing Data</p> <p style="margin:0px;">10 Your Environment</p> <p style="margin:0px;">11 More on Parameters</p> <p style="margin:0px;">12 Loose Ends</p> <p style="margin:0px;">13 Rolo Revisited</p> <p style="margin:0px;">14 Interactive and Nonstandard Shell Features</p> <p style="margin:0px;"> <br> </p> <p style="margin:0px;">A Shell Summary</p> <p style="margin:0px;">B For More Information</p> <p style="margin:0px;"> <br> </p>
