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 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 struc-
tures.
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 file systems having 0 blocks
-B, --block-size=SIZE use SIZE-byte blocks
-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
SIZE may be (or may be an integer optionally followed
by) one of following: kB 1000, K 1024, MB 1000*1000, M
1024*1024, and so on for G, T, P, E, Z, Y.
