This module provides a way to obtain filesystem disk space information. This is a Unix only distribution. If you want to gather this information for Unix and Windows, use Filesys::DfPortable. The only major benefit of using Filesys::Df over Filesys::DfPortable, is that Filesys::Df supports the use of open filehandles as arguments. The module should work with all flavors of Unix, including Mac OS X (Darwin, Tiger, etc), and Cygwin. WWW: https://metacpan.org/release/Filesys-Df
