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

Colophon Our look is the result of reader comments, our own experimentation, and feedback from distribution channels. Distinctive covers complement our distinctive approach to technical topics, breathing personality and life into potentially dry subjects. The animal on the cover of Learning the bash Shell, Third Edition, is a silver bass, one of the 400-500 species of sea bass. The silver bass, also known as the white perch, is found in freshwater bays and river mouths along the Atlantic coast of North America from Nova Scotia to South Carolina, and is most abundant in the Chesapeake region. Silver bass live in large schools and feed on small fishes and crustaceans. Although many bass never stray far from one place their whole lives, silver bass swim upstream to spawn, often becoming landlocked in the process. Like most bass, the silver bass is attracted to bright, shiny objects, and can be drawn quite close to swimmers and divers in this way. Colleen Gorman was the production editor and copyeditor for Learning the bash Shell, Third Edition. MaryAnne Weeks Mayo, Lydia Onofrei, and Emily Quill provided quality control. Peter Ryan provided production assistance. Angela Howard wrote the index. Edie Freedman designed the cover of this book. The cover image is a 19th-century engraving from the Dover Pictorial Archive. Karen Montgomery produced the cover layout with Adobe InDesign CS using Adobe's ITC Garamond font. |
