Cross-platform disk space checking

eb710 has asked for the wisdom of the Perl Monks concerning the following question:

I'm building a distributed processing application that will run on Linux, Mac OS X and Windows (in a Cygwin environment). I'm looking for a way to collect information on available disk space in each of these environments. It looks like Filesys::Statfs does some of what I want, but I also need the next level above that. I want to find all of the (writable, local) file systems on the machine, not just the available space in a single directory. Has anyone dealt with these issues before on one or all of these platforms?

df (disk free) system call certainly works on Linux and Cygwin, and I would presume OS X which is *nix based. Filesys::DiskFree provides an interface to this. cheers tachyon	[reply]

I want to find all of the (writable, local) file systems on the machine, not just the available space in a single directory. If I understand you correctly, you want to know which filesystems are mounted where, so you can query those mount points with Filesys::Statfs, right? I think Sys::Filesystem does that (though it's unclear to me whether it actually supports OS-X) "What should it profit a man, if he should win a flame war, yet lose his cool?"	[reply]
