"Like all the shells available in Linux, the Bourne Again SHell is not only an excellent command line shell, but a scripting language in itself. Shell scripting, allows you to fully utilize the shell's abilities and to automate a lot of tasks that would otherwise require a lot of commands to perform. A lot of programs lying around your Linux box are shell scripts. If you are interested in learning how they work, or in modifying them, it is essential that you understand the bash syntax and semantics. In addition, by understanding the bash language, you will be able to write your own programs to do things exactly the way you want them done..."
"Writing your own shell scripts requires you to know the very basic everyday Linux commands. For example, you should know how to copy, move, create new files, etc. The one thing you must know how to do is to use a text editor. There are three major text editors in Linux, vi, emacs and pico. If you are not familiar with vi or emacs, go for pico or some other easy to use text editor."
