内容简介 * Provides readers with end-to-end shell scripts that can be used to automate repetitive tasks and solve real-world system administration problems * Targets the specific command structure for four popular UNIX systems: Solaris, Linux, AIX, and HP-UX * Illustrates dozens of example tasks, presenting the proper command syntax and analyzing the performance gain or loss using various control structure techniques * Web site includes all the shell scripts used in the book From the Back Cover Discover how to solve real-world system administration problems with this collection of end-to-end shell scripts This comprehensive book takes you step-by-step through the process of writing shell scripts to solve real-world Unix problems and tasks. Each chapter begins by presenting a typical Unix challenge that you’ll most likely experience at your job. With each challenge, you’ll learn how to identify a specific goal and start the shell script by defining the correct command syntax to solve the problem. You’ll find out how to build the shell script around the commands, filter the commands output to strip out the unneeded data, and add options that give users more flexibility on the command line. The approach used will teach you how to attack problems logically. It will also empower you to take the basic command syntax and turn it into a shell scripting solution. Throughout the book, you’ll find end-to-end shell scripts that you can use to automate repetitive tasks and solve real-world system administration problems. These tasks include: Communications such as automated event notification, monitoring processes locally and on remote systems, and automated FTP file transfers Information gathering and monitoring for file systems, paging/swap space, system load, applications, processes, and capturing the system’s configuration Print queue management to keep the printers printing Floating point mathematics in shell scripts using the bc utility The companion Web site contains all of the shell scripts and most of the functions that are discussed in the book as well as bonus shell scripts for various tasks. 作者简介 RANDAL K. MICHAEL is a Unix Systems Administrator at Coca-Cola Enterprises, Inc., where he writes shell scripts to address complex monitoring and event notification issues. He has more than 23 years of industry experience and 10 years of experience as a Unix Systems Administrator, working with Solaris, Linux, AIX, and HP-UX. 内容截图
