mst3000 has asked for the wisdom of the Perl Monks concerning the following question:

I'm trying to expand my programming skills and see if I can get some code to interface with the Windows USN journal.

So, my question: are there any Perl modules in existence that deal with these or has anyone ever directly accessed these through Perl?

If not, is there any other way to execute some Perl code any/every time a file being written is closed under Windows?

Hopefully one of the more experienced monks can help me in my quest. Thanks for your time.

    see if I can get some code to interface with the Windows USN journal.

    By far the simplest way would be to use backticks or a piped open to grab the output from fsutil.exe:

    C:\test>fsutil usn ?
---- USN Commands Supported ----

createjournal   Create a USN journal
deletejournal   Delete a USN journal
enumdata        Enumerate USN data
queryjournal    Query the USN data for a volume
readdata        Read the USN data for a file

    You might also take a look at Win32::ChangeNotify.

    The start of some sanity?
