Please show us the code you've tried that doesn't work. Also explain exactly what you want to have happen, and what problems your current broken code is having.

What have you tried? What didn't work? What about opendir / readdir / closedir has confused you? Are you looking to expand wildcards and don't get glob? Have you tried installing something like Path::Tiny or File::Find::Rule from CPAN?

As asked no one is going to be able to give you more than vague pointers.

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.

Here's a guess...

system "cut -opts $_/file >$_/newfile" for qw( d1 d2 d3 d4 d5 );

Of course, change "-opts" to your actual "cut" flags and "file" and "newfile" to your desired file names.

If this is not what you are looking for, a better description of your problem is needed...

Possibly the laziest of all lazy questions.
