14 containing each file name argument. If no file name is given, the
15 space available on all currently mounted filesystems is shown. Disk
16 space is shown in 1K blocks by default, unless the environment
17 variable POSIXLY_CORRECT is set, in which case 512-byte blocks are

24 filesystem containing the device node (which is always the root
25 filesystem). This version of

28 most kinds of systems doing so requires very nonportable intimate
29 knowledge of filesystem structures.

33 or all filesystems by default.
35 Mandatory arguments to long options are mandatory for short options too.
