bash Cookbook teaches shell scripting the way Unix masters practice the craft. It presents a variety of recipes and tricks for all levels of shell programmers so that anyone can become a proficient user of the most common Unix shell -- the bash shell -- and cygwin or other popular Unix emulation packages. Packed full of useful scripts, along with examples that explain how to create better scripts, this new cookbook gives professionals and power users everything they need to automate routine tasks and enable them to truly manage their systems -- rather than have their systems manage them....
The bash shell is a complete programming language, not merely a glue to combine external Linux commands. By taking full advantage of shell internals, shell programs can perform as snappily as utilities written in C or other compiled languages. And you will see how, without assuming Unix lore, you can write professional bash 4.0 programs through standard programming techniques.
In this quick reference, you'll find everything you need to know about the bash shell. Whether you print it out or read it on the screen, this book gives you the answers to the annoying questions that always come up when you're writing shell scripts: What characters do you need to quote? How do you get variable substitution to do exactly what you want? How do you use arrays? It's also helpful for interactive use. If you're a Unix user or programmer, or if you're using bash on Windows, you'll find this quick reference indispensable....
The Linux command line allows you to type specific Linux commands directly to the system so that you can easily manipulate files and query system resources, thereby permitting you to automate commonly used functions and even schedule those programs to run automatically. This new edition is packed with new and revised content, reflecting the many changes to new Linux versions, including coverage of alternative shells to the default bash shell. For this edition, the author has teamed up with another Linux expert ? with their shared expertise...

This tutorial is designed for beginners only and This tutorial explains the basics of
shell programming by showing some examples of shell programs. Its not help or
manual for the shell. While reading this tutorial you can find manual quite useful (
type man bash at $ prompt to see manual pages). Manual contains all necessary
information you need, but it won't have that much examples, which makes idea
more clear. For that reason, this tutorial contains examples rather than all the
features of shell....
Linux in a Nutshell covers the core commands available on common Linux distributions. This isn't a scaled-down quick reference of common commands, but a complete reference containing all user, programming, administration, and networking commands.
Commands with complete lists of options
Shell syntax for the bash,and tcsh shells
emacs, vi, and ex editing commands
Phần 1 : Getting started with Shell Programming 1. Viết shell script như thế nào ? Bước 1 : dùng bất cứ chương trình gì có thể soạn thảo .

This tutorial assumes no previous knowledge of scripting or programming, but progresses rapidly toward an intermediate/advanced level of instruction . . . all the while sneaking in little nuggets of UNIX® wisdom and lore. It serves as a textbook, a manual for self-study, and as a reference and source of knowledge on shell scripting techniques. The exercises and heavily-commented examples invite active reader participation, under the premise that the only way to really learn scripting is to write scripts....

A working knowledge of shell scripting is essential to everyone wishing to become reasonably adept at system
administration, even if they do not anticipate ever having to actually write a script. Consider that as a Linux
machine boots up, it executes the shell scripts in /etc/rc.d to restore the system configuration and set up
services. A detailed understanding of these startup scripts is important for analyzing the behavior of a system,
and possibly modifying it.
This lab will be using the Linux ps command. The ps command gives a snapshot of the
current processes (or jobs) that are running. Before starting this lab, learn more about the
ps command by typing:
What are some significant switches that can be used with the ps command?
C Shell (csh)
• uses C-like syntax for scripting • I/O more awkward than Bourne shell • nicer for interactive use • job control • history • default prompt is % • uses ˜ symbol to indicate a home directory (user’s or others’)
University Technology Services
Based on the Bourne Shell: • Korn (ksh) • Bourne-Again Shell (bash) • Z Shell (zsh) Based on the C Shell: • T-C shell (tcsh)
