NAME
df - report number of free file system disk blocks
SYNOPSIS
/usr/bin/df [-F FStype][-befgiklnv
][-t|-P][-o specific_options][-V][specialdirectory]...
DESCRIPTION
The
df command displays the number of free 512-byte blocks and free inodes available for file systems by
examining the counts kept in the superblock or superblocks. If a special or a directory is not specified, the
free space on all mounted file systems is displayed. If the arguments to
df are path names, df reports on
the file systems containing the named files. If the argument to
df is a special of an unmounted file system,
the free space in the unmounted file system is displayed.
Options
df recognizes the following options:
-b Report only the number of kilobytes (KB) free.
-e Report the number of files free.
-f Report only the actual count of the blocks in the free list (free inodes are not
reported).
-F FStype Report only on the FStype file system type (see fstyp(1M)).
-g Report the entire structure described in statvfs(2).
-i Report the total number of inodes, the number of free inodes, number of used inodes,
and the percentage of inodes in use.
-k Report the allocation in kilobytes (KB).
-l Report on local file systems only.
-n Report the file system name. If used with no other options, display a list of mounted
file system types.
-o specific_options
Specify options specific to each file system type. specific_options is a comma-separated
list of suboptions intended for a specific FStype module of the command. See the file-
system-specific manual entries for further details.
-P Report the name of the file system, the size of the file system, the number of blocks
used, the number of blocks free, the percentage of blocks used and the directory below
which the file system hierarchy appears.
-t Report the total allocated block figures and the number of free blocks.
-v Report the percentage of blocks used, the number of blocks used, and the number of
blocks free. This option cannot be used with other options.
-V Echo the completed command line, but perform no other action. The command line is
generated by incorporating the user-specified options and other information derived
from /etc/fstab . This option allows the user to verify the command line.
EXTERNAL INFLUENCES
Environment Variables
LC_MESSAGES determines the language in which messages are displayed.
If LC_MESSAGES is not specified in the environment or is set to the empty string, the value of LANG is
used as a default for each unspecified or empty variable. If LANG is not specified or is set to the empty
string, a default of "C" (see lang(5)) is used instead of LANG.
If any internationalization variable contains an invalid setting, df behaves as if all internationalization
variables are set to "C". See environ(5).
International Code Set Support
Single-byte and multi-byte character code sets are supported.
