DESCRIPTION
Show information about the filesystem on which each FILE resides,or all filesystems by default. VMFS included

If an argument is the absolute file name of a disk device node containing a mounted filesystem, vdf+ shows the space available on that filesystem rather than on the filesystem containing the device node (which is always the root filesystem). This version of vdf+ cannot show the space available on unmounted filesystems, because on most kinds of systems doing so requires very nonportable intimate knowledge of filesystem structures.
