If no file name is given, the +space available on all currently mounted file systems is shown. Disk +space is shown in 1K blocks by default, unless the environment +variable POSIXLY_CORRECT is set, in which case 512-byte blocks are +used. +.PP +If an argument is the absolute file name of a disk device node containing a +mounted file system, +.B df +shows the space available on that file system rather than on the +file system containing the device node. This version of +.B df +cannot show the space available on unmounted file systems, because on +most kinds of systems doing so requires very nonportable intimate +knowledge of file system structures. +.SH OPTIONS |
