NAME
df - report file system 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 file system containing each file
name argument. If no file name is given, the space available on all
currently mounted file systems 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 contain-
ing a mounted file system, df shows the space available on that file
system rather than on the file system containing the device node (which
is always the root file system). This version of df cannot show the
space available on unmounted file systems, because on most kinds of
systems doing so requires very nonportable intimate knowledge of file
system structures.
OPTIONS
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 dummy 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.
--total
produce a grand total
-h, --human-readable
print sizes in human readable format (e.g., 1K 234M 2G)
-H, --si
likewise, but use powers of 1000 not 1024
-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)
-P, --portability
use the POSIX output format
--sync invoke sync before getting usage info
-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 environ-
ment variables. Otherwise, units default to 1024 bytes (or 512 if
POSIXLY_CORRECT is set).
SIZE is an integer and optional unit (example: 10M is 10*1024*1024).
Units are K, M, G, T, P, E, Z, Y (powers of 1024) or KB, MB, ... (pow-
ers of 1000).
