''Unix in Easy Steps'' instructs the reader how to use the BASH command-line interface and how to employ BASH's powerful programming abilities. Complete examples illustrate each aspect with colorized source code and full-color screenshots depict the actual output. The book begins by demonstrating BASH commands for system navigation and file manipulation so the reader can 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, and environment customization. It then introduces BASH programming with examples of flow control, command switches, input/output, job control, and program debugging -- allowing the reader to create their 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, and those wanting to learn programming skills by writing useful shell scripts. It also appeals to the student who is studying programming at school or college and those seeking a career in computing and need a fundamental understanding of the BASH interpreter on Unix-based operating systems.
