NAME |
|||
df - report filesystem 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 filesystem containing each file |
|||
name argument. If no file name is given, the space available on all |
|||
currently mounted filesystems 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 filesystem, df shows the space available on that filesys- |
|||
tem rather than on the filesystem containing the device node (which is |
|||
always the root filesystem). This version of df cannot show the space |
|||
available on unmounted filesystems, because on most kinds of systems |
|||
doing so requires very nonportable intimate knowledge of filesystem |
|||
structures. |
|||
OPTIONS |
|||
Show information about the filesystem on which each FILE resides, or |
|||
all filesystems by default. |
|||
Mandatory arguments to long options are mandatory for short options |
|||
too. |
|||
-a, --all |
|||
include filesystems 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 filesystems |
|||
--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 filesystems of type TYPE |
|||
-T, --print-type |
|||
print filesystem type |
|||
-x, --exclude-type=TYPE |
|||
limit listing to filesystems 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 fol- |
|||
lowing: kB 1000, K 1024, MB 1,000,000, M 1,048,576, and so on for G, T, |
|||
P, E, Z, Y. |
