The goal of this book is to introduce readers to
an assortment of powerful command line utilities that can be combined to
create simple, yet powerful shell scripts. While all examples and
scripts use the “bash” command set, many of the concepts translate into
other forms of shell scripting (ksh, sh, csh), including the concept of
piping data between commands, regular expression substitution and the
sed and awk commands. Aimed at a reader relatively new to working in a
bash environment, the book is comprehensive enough to be a good
reference and teach a few new tricks to those who already have some
experience with creating shells scripts. The book features companion
files with code samples from the book (available with Amazon proof of
purchase for free downloading from the publisher by writing
