I'm trying to understand the behaviour of several big perl apps that use many custom modules. They read and write lots of files in a directory tree.

I'd like to be able to get a list of which files were read or written by the process.

I was hoping there would be a handy module on CPAN which would override CORE::GLOBAL::open (and symlink, rename, etc. etc.) to keep a record of the calls and parameters.

I couldn't see one. Is there one I'm missing?
