UNIX in Easy Steps

Unix in easy
steps demonstrates how to get the most from any Unix-based
operating system using the built-in BASH shell interpreter - the "Bourne
Again SHell" (BASH). This is the default shell for Linux distributions
(such as Ubuntu), Mac OS X, Solaris, and for the Raspbian operating system on
Raspberry Pi devices.

This book will show you how to use the
BASH command-line interface and how to employ BASH's powerful programming
abilities. Complete examples illustrate each aspect with colourised source code
and full-colour screenshots depict the actual output.

Unix
in easy steps begins by demonstrating BASH commands for system navigation
and file manipulation so you will quickly become familiar with the command-line
interface. It explains all the BASH basics before moving on to describe
advanced features such as:

• Command
  history.
• Command-line editing.
• Environment
  customisation.

This book then introduces BASH
programming with examples of flow control, command switches, input/output, job
control, and program debugging - allowing you to create your own executable
programs by copying the book's examples.

Unix
in easy steps has an easy-to-follow style that will appeal to:

• Users
  who are completely new to Unix-based operating
  systems.
• Casual users who wish to expand their knowledge of
  their computer system.
• Those who would like to learn
  programming skills by writing useful shell scripts.
• The
  student who is studying programming at school or
  college.
• Those seeking a career in computing and need a fundamental
  understanding of the BASH interpreter on Unix-based operating
  systems.
