O'Reilly's bestselling book on Linux's bash shell is at it again. Now that Linux is an established player both as a server and on the desktop Learning the bash Shell has been updated and refreshed to account for all the latest changes. Indeed, this third edition serves as the most valuable guide yet to the bash shell. As any good programmer knows, the first thing users of the Linux operating system come face to face with is the shell the UNIX term for a user interface to the system. In other words, it's what lets you communicate with the computer via the keyboard and display. Mastering the bash shell might sound fairly simple but it isn't. In truth, there are many complexities that need careful explanation, which is just what Learning the bash Shell provides. If you are new to shell programming, the book provides an excellent introduction, covering everything from the most basic to the most advanced features. And if you've been writing shell scripts for years, it offers a great way to find out what the new shell offers. Learning the bash Shell is also full of practical examples of shell commands and programs that will make everyday use of Linux that much easier. With this book, programmers will 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 without programming The nuts and bolts of basic shell programming, flow control structures, command-line options and typed variables Process handling, from job control to processes, coroutines and subshells Debugging techniques, such as trace and verbose modes Techniques for implementing system-wide shell customization and features related to system security

Learning the Bash Shell

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. The book covers all of bash's features, both for interactive use and programming.

"Learning the Korn Shell" is the key to the Korn shell and becoming adept at using it as an interactive command and scripting language. Readers will learn how to write many applications more easily and quickly than with other high-level languages. This newly revised title inherits a long tradition of trust among computer professionals.

"This is a book about how technology has affected the music industry through a series of disruptions that have taken place ten times over the past century. Whenever technological innovations result in a compelling new way to distribute music to the public, the music industry changes in myriad and fundamental ways to adjust to the new format. And while the technologies themselves have evolved over the decades, the changes within the business follow a distinct pattern. Key Changes describes this pattern: it defines an analytical structure, the 6C Framework, that explains how the music business transformed in each era. The ten disruptions are the formats for distributing recorded music: phonograph records, radio, LPs, tapes, CDs, television, digital downloads, streaming, and streaming video; and then into the future with voice response and AI technologies, where the changes are in progress now. Each of these has a chapter in the book. The book concludes with an examination of how the 6C Framework applies across the timeline of various music formats, as well as to technologically induced changes in other industries, ranging from movies to sports to coffee, and it offers some observations about how blockchain technology could be the source of the next set of disruptive innovations in the music industry"--

Finally, Learning the bash Shell, Second Edition, shows you how to acquire, install, configure, and customize bash, and gives advice to system administrators managing bash for their user community.

This Nutshell Handbook® is a thorough introduction to the Korn shell, both as a user interface and as a programming language.The Korn shell, like the C and Bourne shells, is a program that interprets UNIX commands. It has many features that aren't found in other shells, including command history (the ability to recall and edit previous commands). The Korn shell is also faster; several of its features allow you to write programs that execute more quickly than their Bourne or C shell equivalents.This book provides a clear and concise explanation of the Korn shell's features. It explains ksh string operations, co-processes, signals and signal handling, and one of the worst "dark corners" of shell programming: command-line interpretation. It does this by introducing simple real-life examples and then adding options and complexity in later chapters, illustrating the way real-world script development generally proceeds. An additional (and unique) programming aid, a Korn shell debugger (kshdb), is also included.Learning the Korn Shell is an ideal resource for many UNIX users and programmers, including software developers who want to "prototype" their designs, system administrators who want to write tools for their own use, and even novices who just want to use some of ksh's more advanced interactive features.
