G'day rajand,

Welcome to the Monastery.

As you can see, your post has not been well received. Please read "How do I post a question effectively?" to understand why, and learn how you can improve any subsequent posts.

In the Tutorials section of the online documentation you'll find FAQs. The most relevant section for your question would be "perlfaq5 - Files and Formats". And, within that section, you'll find "How do I traverse a directory tree?" which is possibly exactly what you want.
