Hi Ravi. As John pointed out (but not in so many words) the built-in 'chdir' will change the default directory for your script, but won't change the PWD environment variable. The standard 'Cwd' module gives you two alternative ways around this. It will provide a 'cwd' function which will return the value of your current default directory, or (when incorporated with 'use Cwd "chdir"') will give you an alternative 'chdir' function which behaves identically to the built-in one but keeps the value of PWD in synch with your current location.
