I am entering into the world of Unix OS. I intend to write a simple shell script which runs a java program. My java program takes three VM arguments and classpath of various directories.Let the root directory be ab_root.
Can some one please guide me to a sample script for such tasks ?

Also I am having a hard time mugging up basic unix commands. Not too sure if its the lack of interest or what.

First, figure out how to run what you want to run from the command line. For example:

To turn that into a script, add a line identifying the script processor. For example:

If you would like to pass the arguments to the script, change it to:

Now you can run it as (assume the script is named "runmyapp"):

For more help, type "man bash" on the command line. You will get a lot of output, but everything about shell script syntax is in there.

Another hint: most Java apps are run by scripts. Study their scripts - look in the bin directory.
