NAME
|
||
|
|
df (generic) - 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.
|
||
|
|
