libfilesys-df-perl 0.92-6build3 (arm64 binary) in ubuntu disco

 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.
