HI (again) Ani:

Like anything, learning takes patience and practice. Looking at other people's scripts and dissecting what and how they do what they do is very instructive. Experiment with various commands at the command line using their various applicable options. Not only is this one way to understand what someone else has written, but it is one way to add to your own toolbox. Read the manpages!

One site that you should find helpful (with many good scripts, some tutorials, and a number of pointers to other references) is:

First know programming is important, and if possible in a structurated way, I mean. http://en.wikipedia.org/wiki/Structured_programming . Then there are languages oriented to this basis and others rely more on the programmer's style. Personally I think that is the basis and then, obviously, know the programming language (commands, syntax, etc). Lot of time and programming lines helps you to improve your style. It is never enough and always learn new things. Also read about modular programming. In fact, a good environment (coach, books, practice) is the key to develop a good programming style.

About a specific shell scripting documentation, looks for workbook or by example styles.
