"By Chapter 7, Bash Cookbook extends out of Bash commands and
begins exploring combining the power of bash scripting with useful
command such as grep, awk, and sed. To quote the authors, "if our
scripting examples are going to tackle real-world problems, they
need to use the wider range of tools that are actually used by
real-world bash users and programmers." And that is exactly what
they do. This chapter alone gave me the ability to do more in the
command line environment simply by explaining the functions of the
scripts put forth."
