"Classic Shell Scripting" by Arnold Robbins and Nelson H. Beebe is a decent text on portable shell scripting, which also contains a fair amount of awk. Though written in tutorial form, it explicitly assumes that the reader knows how to use the shell interactively and, as I show below, in some cases implicitly assumes that the reader already Cited by: A download that includes scripts and lessons used in the book.

Parker, Steve (Author). Classic Shell Scripting is written to help you reliably navigate these tricky g shell scripts requires more than just a knowledge of the shell language, it also requires familiarity with the individual Unix programs: why each one is there, how to use them.

The shell can read this file and act on the commands as if they were typed on the keyboard. Shell scripting is used to automate day-to-day administration, and for testing or product development tasks. This book covers Bash, GNU Bourne Again SHell, preparing you to work in the exciting world of Linux shell scripting.

This book is an exploration of Shell programming, also referred to as Bash Scripting. It begins by guiding you on how to automate the various tasks in UNIX by using the Shell scripts.

The book also guides you on the effective steps on how to write the Shell scripts.3/5(6). Linux Shell Scripting Cookbook, Second Edition This book contains a total of 9 chapters spread over 40 pages.

This book is written by Shantanu Tushar who is a GNU/Linux user since his early days. This guide contains a balanced combination of theory and practical. A shell script is a computer program designed to be run by the Unix shell, a command line interpreter. It is a text file containing a sequence of shell commands and constructs that perform a routine task.

This sequence is typically executed by entering the name of the script on the command line. GNU Bash is a complete implementation of the POSIX2 shell specification (/bin/sh), with additional features from the C-shell (csh) and Korn shell (ksh). The name is an acronym for the ‘Bourne-Again SHell’, a pun on Stephen Bourne, the author of the direct ancestor of the current Unix shell sh, which appeared in the Seventh Edition Bell Labs.

We will be using Bash, an acronym [3] for "Bourne-Again shell" and a pun on Stephen Bourne's now classic Bourne shell.

Bash has become a de facto standard for shell scripting on most flavors of UNIX. Most of the principles this book covers apply equally well to scripting with other shells, such as the Korn Shell. A shell allows execution of gnu commands, both synchronously and asynchronously.

The shell waits for synchronous commands to complete before accepting more input; asyn-chronous commands continue to execute in parallel with the shell while it reads and executes additional commands. The redirection constructs permit fine-grained control of the input.

This book is for students and Linux System Administrators. It provides the skills to read, write, and debug Linux shell scripts using bash shell. The book begins by describing Linux and simple scripts to automate frequently executed commands and continues by describing conditional logic, user interaction, loops, menus, traps, and functions.

1. Bash Guide for Beginners This book contains a total of 12 chapters spread over pages. This book is written by Machtelt Garrels. This book is must for anyone working on UNIX and like environment.

The world's best conceptual introduction to shell scripting comes from an old AT&T training the video, Brian W. Kernighan (the "K" in awk) and Lorinda L. Cherry (co-author of bc) demonstrate how one of the founding principles of UNIX was to empower users to leverage existing utilities to create complex and customized tools.

In the words of Kernighan: "Think of the UNIX system. I plan to buy a shell scripting book. Please suggest me a best book for shell Scripting. It will be great if the book contains more examples.

When you have any experience then it will be beneficial to understand quickly, however, we will make you understand the concept and implementation of shell scripting.

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 snippets of UNIX ® wisdom and serves as a textbook, a manual for self-study, and a reference and source of knowledge on shell scripting techniques.

By the time the last edition of OReillys Classic Shell Scripting was published inthe approach it used was already somewhat out of date and the readership it addressed on the way out. The authors assumed that one is using any one of a number of old commercial versions of Unix, and might just be sharing a system with a number of other users, when nowadays most people doing anything /5(15).

With Classic Shell Scripting you'll avoid hours of wasted effort. You'll learn not only write useful shell scripts, but how to do it properly and ability to program and customize the shell quickly, reliably, and portably to get the best out of any individual system is an important skill for anyone operating and maintaining Unix or Reviews: Working with Shell Scripting.

Check out the Shell Style Guide on GitHub to get started. Also, Apple has a document on shell script security that's also well worth a read. Be careful out there. A little extra time making sure your scripts are safe from major known risks is.

The single statement works fine as long as you use Bash or a shell compatible with the commands used in the script. If no shell is specified in the script, the default shell will be used to execute the script commands. The next task is to ensure that the script will run using the Bash shell, even if another shell is the default.
