NAME
df - report filesystem disk space usage
SYNOPSIS
df [options] [file...]
POSIX options: [-kP] [--]
GNU options (shortest form): [-ahHiklmPv] [-t fstype] [-x
fstype] [--block-size=size] [--print-type] [--no-sync]
[--sync] [--help] [--version] [--]
DESCRIPTION
df reports the amount of disk space used and available on
filesystems.
With no arguments, df reports the space used and available
on all currently mounted filesystems (of all types). Oth-
erwise, df reports on the filesystem containing each argu-
ment file.
POSIX DETAILS
The output is in 512-byte units by default, but in
1024-byte units when the -k option is given. The output
format is undefined, unless the -P option is given. If
file is not a regular file, a directory or a FIFO, the
result is unspecified.
GNU DETAILS
The output is in 1024-byte units (when no units are speci-
fied by options), unless the environment variable
POSIXLY_CORRECT is set, in which case POSIX is followed.
If an argument file is a disk device file containing a
mounted filesystem, df shows the space available on that
filesystem rather than on the filesystem containing the
device node.
POSIX OPTIONS
-k Use 1024-byte units instead of the default 512-byte
units.
-P Output in six columns, with heading `Filesystem N-
blocks Used Available Capacity Mounted on' (with
N=512, but N=1024 when the -k option is given).
-- Terminate option list.
GNU OPTIONS
-a, --all
Include in the listing filesystems that have a size
of 0 blocks, which are omitted by default. Such
filesystems are typically special-purpose pseudo-
filesystems, such as automounter entries. Also,
filesystems of type "ignore" or "auto", supported
by some operating systems, are only included if
this option is specified.
--block-size=size
Print sizes in blocks of size bytes. (New but bro-
ken in fileutils-4.0.)
-h, --human-readable
Append a size letter such as M for binary megabytes
(`mebibytes') to each size.
-H, --si
Do the same as for -h, but use the official SI
units (with powers of 1000 instead of 1024, so that
M stands for 1000000 instead of 1048576). (New in
fileutils-4.0.)
-i, --inodes
List inode usage information instead of block
usage. An inode (short for index node) contains
information about a file such as its owner, permis-
sions, timestamps, and location on the disk.
-k, --kilobytes
Print sizes in 1024-byte blocks.
-l, --local
Limit the output to local filesystems only. (New
in fileutils-4.0.)
-m, --megabytes
Print sizes in binary megabyte (that's 1048576
bytes) blocks. Note that the four options -h, -H,
-k, -m are mutually exclusive and only the last one
is effective; for example, it is not the case that
giving both the --si and -m options would result in
output in (actual, 1000000-byte) megabytes. [The
interpretation of blocksizes is also influenced by
the environment variable BLOCK_SIZE, but this does
not work in the fileutils-4.0 version.]
--no-sync
Do not invoke the sync system call before getting
any usage data. This may make df run significantly
faster, but on some systems (notably SunOS) the
results may be slightly out of date. This is the
default.
-P, --portability
Use the POSIX output format. This is like the
default format except that the information about
each filesystem is always printed on exactly one
line; a mount device is never put on a line by
itself. This means that if the mount device name
is more than 20 characters long (e.g., for some
network mounts), the columns are misaligned.
--sync Invoke the sync system call before getting any
usage data. On some systems (notably SunOS), doing
this yields more up to date results, but in general
this option makes df much slower, especially when
there are many or very busy filesystems.
-t fstype, --type=fstype
Limit the listing to filesystems of type fstype.
Multiple filesystem types can be specified by giv-
ing multiple -t options. By default, nothing is
omitted.
-T, --print-type
Print each filesystem's type. The types given are
those reported by the system (and are found in a
system-dependent way, for example by reading
/etc/mtab). See also mount(.
-x fstype, --exclude-type=fstype
Limit the listing to filesystems not of type
fstype. Multiple filesystem types can be elimi-
nated by giving multiple -x options. By default,
no filesystem types are omitted.
-v Ignored; for compatibility with System V versions
of df.
GNU STANDARD OPTIONS
--help Print a usage message on standard output and exit
successfully.
--version
Print version information on standard output, then
exit successfully.
-- Terminate option list.
ENVIRONMENT
The variable POSIXLY_CORRECT determines the choice of
unit. If it is not set, and the variable BLOCKSIZE has a
value starting with `HUMAN', then behaviour is as for the
-h option, unless overridden by -k or -m options. The
variables LANG, LC_ALL, LC_CTYPE and LC_MESSAGES have the
usual meaning.

POSIX 1003.2
