اسکریپت‌نویسی حرفه‌ای: [هر آنچه همیشه می‌خواستید درباره اسکریپت‌نویسی بدانید اما از پرسیدن می‌ترسیدید]

The book is meant for the intermediate shell coder up to the advanced shell-code hacker,because I don’t explain many basic programming structures.This is not to say that the beginner won’t find this book useful it may work well as a supplementaryreference to a more traditional shell-scripting training guide. But there is a differencebetween learning English as a second language and learning how to apply sarcasm. This bookis like sarcasm in that example it assumes some basic shell-code literacy.I go into great detail about how and why the scripts were written in their present form,and I include some explanation of how to avoid certain problems. Much of my learningcame from sources heavy in obfuscation and light on clarity, so I tried to be as explicit aspossible, and favored explaining too much rather than too little. You can think of manychapters I included as shell scripts with extremely detailed commentary. Annotation System administrators need libraries of solutions that are ingenious but understandable. They don't want to reinvent the wheel, but they don't want to reinvent filesystem management either! Expert Shell Scripting is the ultimate resource for all working Linux, Unix, and OS X system administrators who would like to have short, succinct, and powerful shell implementations of tricky system scripting tasks. Automating small to medium system management tasks Analyzing system data and editing configuration files Scripting Linux, Unix, and OS X applications using bash, ksh, et al. What you'll learn Debug shell scripts using existing debuggers, not inspection. Use and extend text-editing one-liners and learn to forget Perl. Manage files and filesystems using scripting, not inflexible utilities. Use scripts to build complete Linux systems. Script X Window without getting lost in configuration files. Ignore Python, and script in bash and ksh instead. Who this book is for System administrators who need solutions to everyday problems "Expert Shell Scripting is a cornucopia of useful scripts and techniques collected during my years as a system administrator. Although these scripts were written from the perspective of a system administrator, you can reuse them for almost any purpose you can think of. All the code in this book demonstrates either something very useful or something unique (and possibly quite out of the ordinary). Many techniques represent solutions that would be difficult to come up with on your own." "My goal with this book is to provide greater depth than a beginning shell-scripting book by explaining not just what the code does, but in most cases how and why the specific logic was chosen. These scripts will greatly add to your scripting repertoire and increase your skill in tackling problems and choosing solutions. Most of the scripts in this book have evolved and been hardened over years in a production environment where reliability is key. This book will be an excellent resource for anyone who wants a collection of examples at their fingertips."--Jacket Ron Peters. Title And Date Taken From Resource Description Page (july 6, 2009).
