NAME
df - report filesystem disk space usage
SYNOPSIS
df
[OPTION]... [FILE]...
DESCRIPTION
This manual page
documents the GNU version of
df.
df
displays the amount of disk space available on the filesystem
containing each file name argument. If no file name is given, the
space available on all currently mounted filesystems 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.
If an argument is the absolute file name of a disk device node containing a
mounted filesystem,
df
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
df
cannot show the space available on unmounted filesystems, because on
most kinds of systems doing so requires very nonportable intimate
knowledge of filesystem structures.
OPTIONS
Show information about the filesystem on which each FILE resides,
or all filesystems by default.

-
use the POSIX output format
- --sync
-
invoke sync before getting usage info
- -t, --type=TYPE
-
limit listing to filesystems of type TYPE
