DF(1) User Commands DF(1)
df - report file system space usage
df [OPTION]... [FILE]...
This manual page documents the GNU version of df. df displays
the amount of space available on the file system containing each
file name argument. If no file name is given, the space
available on all currently mounted file systems is shown. 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 device node
containing a mounted file system, df shows the space available on
that file system rather than on the file system containing the
device node. This version of df cannot show the space available
on unmounted file systems, because on most kinds of systems doing
so requires non-portable intimate knowledge of file system
structures.
Show information about the file system on which each FILE
resides, or all file systems by default.
Mandatory arguments to long options are mandatory for short
options too.
-a, --all
include pseudo, duplicate, inaccessible file systems
-B, --block-size=SIZE
scale sizes by SIZE before printing them; e.g., '-BM'
prints sizes in units of 1,048,576 bytes; see SIZE format
below
-h, --human-readable
print sizes in powers of 1024 (e.g., 1023M)
-H, --si
print sizes in powers of 1000 (e.g., 1.1G)
-i, --inodes
list inode information instead of block usage
-k like --block-size=1K
-l, --local
limit listing to local file systems
--no-sync
do not invoke sync before getting usage info (default)
--output[=FIELD_LIST]
use the output format defined by FIELD_LIST, or print all
fields if FIELD_LIST is omitted.
-P, --portability
use the POSIX output format
--sync invoke sync before getting usage info
--total
elide all entries insignificant to available space, and
produce a grand total
-t, --type=TYPE
limit listing to file systems of type TYPE
-T, --print-type
print file system type
-x, --exclude-type=TYPE
limit listing to file systems not of type TYPE
-v (ignored)
--help display this help and exit
--version
output version information and exit
Display values are in units of the first available SIZE from
--block-size, and the DF_BLOCK_SIZE, BLOCK_SIZE and BLOCKSIZE
environment variables. Otherwise, units default to 1024 bytes
(or 512 if POSIXLY_CORRECT is set).
The SIZE argument is an integer and optional unit (example: 10K
is 10*1024). Units are K,M,G,T,P,E,Z,Y,R,Q (powers of 1024) or
KB,MB,... (powers of 1000). Binary prefixes can be used, too:
KiB=K, MiB=M, and so on.
FIELD_LIST is a comma-separated list of columns to be included.
Valid field names are: 'source', 'fstype', 'itotal', 'iused',
'iavail', 'ipcent', 'size', 'used', 'avail', 'pcent', 'file' and
'target' (see info page).
