The Advanced Bash Scripting Guide by Mendel Cooper is both a reference and a tutorial on shell scripting. This freely available comprehensive book (the equivalent of about 612 print pages) covers almost every aspect of shell scripting. It contains 300 profusely commented illustrative examples (including such goodies as an anti-spammer script), and a number of tables. Not just a shell scripting tutorial, this book also provides an introduction to basic programming techniques, such as sorting and recursion. It is well suited for either individual study or classroom use. 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 lore. It serves as a textbook, a manual for self-study, and 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.
