This tutorial is designed for beginners only and This tutorial explains the basics of
shell programming by showing some examples of shell programs. Its not help or
manual for the shell. While reading this tutorial you can find manual quite useful (
type man bash at $ prompt to see manual pages). Manual contains all necessary
information you need, but it won't have that much examples, which makes idea
more clear. For that reason, this tutorial contains examples rather than all the
features of shell. I assumes you have at least working knowledge of Linux i.e. basic
commands like how to create, copy, remove files/directories etc or how to use
editor like vi or mcedit and login to your system. Before Starting Linux Shell Script
Programming you must know
● Kernel
● Shell
● Process
● Redirectors, Pipes, Filters etc.
