-a

include pseudo, duplicate, inaccessible file systems

-B

scale sizes by SIZE before printing them; e.g., '-BM' prints sizes in units of 1,048,576 bytes; see SIZE format below

-h

print sizes in powers of 1024 (e.g., 1023M)

-H

print sizes in powers of 1000 (e.g., 1.1G)

-i

list inode information instead of block usage

-k

like --block-size=1K

-l

limit listing to local file systems

--no-sync

do not invoke sync before getting usage info (default)

--output[

use the output format defined by FIELD_LIST, or print all fields if FIELD_LIST is omitted.

-P

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

limit listing to file systems of type TYPE

-T

print file system type

-x

limit listing to file systems not of type TYPE

--help

display this help and exit

--version

output version information and exitDisplay values are in units of the first available SIZE from --block-size, and the DF_BLOCK_SIZE, BLOCK_SIZE and BLOCKSIZE environ‐ment 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 (powers of 1024) or KB,MB,...(powers of 1000).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).AUTHORWritten by Torbjorn Granlund, David MacKenzie, and Paul Eggert.REPORTING BUGSGNU coreutils online help: <http://www.gnu.org/software/coreutils/>Report df translation bugs to <http://translationproject.org/team/>COPYRIGHTCopyright © 2017 Free Software Foundation, Inc.
