This tutorial is designed for beginners only and explains the basics of shell programming by showing some examples of shell programs. Many other tutorial and books on Linux shell scripting are either too basic, or skips important intermediate steps. But this tutorial, maintained the balance between these two. It covers the many real life modern example of shell scripting which are almost missed by many other tutorials/documents/books. I have used a hands-on approach in this tutorial. The idea is very clear "do it yourself or learn by doing"" i.e. trying things yourself is the best way to learn, so examples are presented as complete working shell scripts, which can be typed in and executed. This is updated and in new easy to read format tutorial.
