NAME
df_hfs: df - report number of free CDFS, HFS, or NFS file system disk blocks
SYNOPSIS
/usr/bin/df [-F FStype][-befgiklntv
][-B][-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.
-B Report the total number of blocks allocated for swapping to the file system as well
as the number of blocks free for swapping to the file system. This option is sup-
ported on HFS file systems only.
-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). When this option is specified, df reports on raw devices.
-F FStype Report only on the FStype file system type (see fstyp(1M)). For the purposes of this
manpage, FStype can be one of cdfs, hfs, and nfs, for the CDFS, HFS, and NFS
file systems, respectively.
-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 the HFS file system type. specific_options is a comma-
separated list of suboptions.
The available suboption is:
i Report the number of used and free inodes.
-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.
When
df is used on an HFS file system, the file space reported is the space available to the ordinary user,
and does not include the reserved file space specified by fs_minfree.
Unreported reserved blocks are available only to users who have appropriate privileges. See tunefs(1M)
for information about
fs_minfree.
When
df is used on NFS file systems, the number of inodes is displayed as −1 . This is due to superuser
access restrictions over NFS.
