You could write your own using File::Find, File::Copy or use Rsync, for which I'm sure a perl module exists.

G'day shan_emails,

There's a number of built-in modules that you could use for these various tasks. Here's a selection from the File:: namespace that seem to be the most relevant (you may find others to be useful):

• File::Find - Traverse a directory tree
• File::Compare - Compare files or filehandles
• File::Path - Create or remove directory trees
• File::Copy - Copy files or filehandles

Here it is: File::Rsync.

"...if that folder/file is not found then copy that ..."

Uh, copying an undef or nul seems fairly pointless. Do you mean 'copy what was found in one into the other?'; 'create a log entry documenting what was NOT found in one that was in the other?' or something else?

Basically i am comparing two folder (source folder and target folder).

In the target folder the source folder files/subfolders are not found then copy them. Else if it is found then don't copy that file instead log them stating that respective file already exists.

OK, that's what I suspected and others discerned to be your meaning. Now let me give you a 'simple english' version that's wordy but utterly unambiguous:

"I'm comparing two folders. If a file or subfolder is NOT found in the second but is present in the first, copy the missing item from the first to the second; otherwise... simply log that a file or dir was found in BOTH folders."

Note that this expression does NOT concern itself with items found in the second folder, but not the first. That's a different requirement and requires a different problem statement.

As with programming, communicating anything even mildly complex depends heavily on clarity and precision.
