Break through the practice of writing tedious code with shell scripts Key Features Learn to impeccably build shell scripts and develop advanced applications Create smart solutions by writing and debugging scripts A step-by-step tutorial to automate routine tasks by developing scripts Book Description Linux is the most powerful and universally adopted OS. Shell is a program that gives the user direct interaction with the operating system. Scripts are collections of commands that are stored in a file. The shell reads this file and acts on commands as if they were typed on the keyboard. Learning Linux Shell Scripting covers Bash, GNU Bourne Again Shell, preparing you to work in the exciting world of Linux shell scripting. CentOS is a popular rpm-based stable and secured Linux distribution. Therefore, we have used CentOS distribution instead of Ubuntu distribution. Linux Shell Scripting is independent of Linux distributions, but we have covered both types of distros. We start with an introduction to the Shell environment and basic commands used. Next, we explore process management in Linux OS, real-world essentials such as debugging and perform Shell arithmetic fluently. You'll then take a step ahead and learn new and advanced topics in Shell scripting, such as decision making, starting up a system, and customizing a Linux environment. You will also learn about grep, stream editor, and AWK, which are very powerful text filters and editors. Finally, you'll get to grips with taking backup, using other language scripts in Shell Scripts as well as automating database administration tasks for MySQL and Oracle. By the end of this book, you will be able to confidently use your own shell scripts in the real world. What you will learn Familiarize yourself with the various text filtering tools available in Linux Understand expressions and variables and how to use them practically Automate decision-making and save a lot of time and effort of revisiting code Get to grips with advanced functionality such as using traps, dialogs to develop screens & Database administration such as MySQL or Oracle Start up a system and customize a Linux system Taking backup of local or remote data or important files. Use existing other language scripts such as Python, Perl & Ruby in Shell Scripts Who this book is for Learning Linux Shell Scripting is ideal for those who are proficient at working with Linux and want to learn about shell scripting to improve their efficiency and practical skills.

If you're like most UNIX users, you have a job to do aside from exploring your operating system - like analyzing that hot new stock, running another experiment, or typesetting another report. What happens when you have problems? What happens when the system slows to a crawl, when you can't get logged back in after a power failure, or when you've sent a file to the printer three times but have yet to find a printout? When You Can't Find Your UNIX System Administrator is written to give you tools for solving problems. We provide practical solutions for problems you're likely to encounter in logging in, running programs, sharing files, managing space resources, printing, and so on; just enough background so that you can make sense of our suggestions, rather than simply memorizing keystrokes; an explanation of how to present problems to your system administrator so that you're more likely to get quick, accurate support; a list of the site-specific information to which you should have access, and a place to write it down; and a Quick Reference worksheet summarizing what to try first, second, third for commonly encountered problems. The goal of this book is not to make you a guru, but to get you back to the job you'd rather be doing.

The first thing users of the Linux operating system come face to face with is the shell. "Shell" is the UNIX term for a user interface to the system -- something that lets you communicate with the computer via the keyboard and display. Bash, the Free Software Foundation's "Bourne Again Shell," is the default shell for Linux, the popular free UNIX-like operating system. It's also a replacement for the standard UNIX Bourne shell, which serves both as a user interface and as a programming language. Like the FSF's other tools, bash is more than a mere replacement: it extends the Bourne shell in many ways. Features include command line editing, key bindings, integrated programming features, command completion, control structures (especially the select construct, which enables you to create menus easily), and new ways to customize your environment. Whether you want to use bash for its user interface or its programming features you will find Learning the bash Shell a valuable guide. The book covers all of bash 's features, both for interactive use and programming. If you are new to shell programming, Learning the bash Shell provides an excellent introduction, covering everything from the most basic to the most advanced features, like signal handling and command line processing. If you've been writing shell scripts for years, it offers a great way to find out what the new shell offers. The book is full of examples of shell commands and programs that are designed to be useful in your everyday life as a user, not just to illustrate the feature being explained. All of these examples are freely available to you online on the Internet. This second edition covers all of the features of bash Version 2.0, while still applying to bash Version 1.x. New features include the addition of one-dimensional arrays, parameter expansion, and more pattern-matching operations. bash 2.0 provides even more conformity with POSIX.2 standards, and in POSIX.2 mode is completely POSIX.2 conformant. This second edition covers several new commands, security improvements, additions to ReadLine, improved configuration and installation, and an additional programming aid, the bash shell debugger. With this book you'll learn: How to install bash as your login shell The basics of interactive shell use, including UNIX file and directory structures, standard I/O, and background jobs Command line editing, history substitution, and key bindings How to customize your shell environment witho ...

For a company that promised to "put a pause on new features," Apple sure has been busy-there's barely a feature left untouched in Mac OS X 10.6 "Snow Leopard."

You get all the answers with jargon-free introductions to: Big-ticket changes. A 64-bit overhaul. Faster everything. A rewritten Finder. Microsoft Exchange compatibility. All-new QuickTime Player. If Apple wrote it, this book covers it. Snow Leopard Spots. This book demystifies the hundreds of smaller enhancements, too, in all 50 programs that come with the Mac: Safari, Mail, iChat, Preview, Time Machine. Shortcuts. This must be the tippiest, trickiest Mac book ever written. Undocumented surprises await on every page. Power usage. Security, networking, build-your-own Services, file sharing with Windows, even Mac OS X's Unix chassis-this one witty, expert guide makes it all crystal clear.
