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 transfersInformation gathering and monitoring for file systems, paging/swap space, system load, applications, processes, and capturing the system’s configurationPrint queue management to keep the printers printingFloating point mathematics in shell scripts using the bc utilityThe 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.
