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

I'm working on a script that will monitor the percentage of disk used on a UNIX filesystem. I probably will use `df` if I have to, but I'd prefer an all Perl solution. I've done some hunting for a Perl module that will do it for me, but I've come up with nothing so far. Does anyone know of a module in CPAN (or one that is already installed by default) that will give me this information?
