NAME
df - report file system disk space usage
SYNOPSIS
df [OPTION]... [FILE]...
DESCRIPTION
This manual page documents the GNU version of df. df dis-
plays 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 containing 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

User Commands DF(1)
-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 BLOCK-
SIZE environment 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, ... (powers of 1000).
