15 df - report filesystem disk space usage
16 !!SYNOPSIS
17
18
19 __df__ [[''OPTION'']... [[''FILE'']...
20 !!DESCRIPTION
21
22
23 This manual page documents the GNU version of __df__.
24 __df__ displays the amount of disk space available on the
25 filesystem containing each file name argument. If no file
26 name is given, the space available on all currently mounted
27 filesystems is shown. Disk space is shown in 1K blocks by
28 default, unless the environment variable POSIXLY_CORRECT is
29 set, in which case 512-byte blocks are used.
30
31
32 If an argument is the absolute file name of a disk device
33 node containing a mounted filesystem, __df__ shows the
34 space available on that filesystem rather than on the
35 filesystem containing the device node (which is always the
36 root filesystem). This version of __df__ cannot show the
37 space available on unmounted filesystems, because on most
38 kinds of systems doing so requires very nonportable intimate
39 knowledge of filesystem structures.
