NAME

       bdf - report number of free disk blocks (Berkeley version)

SYNOPSIS

       type [filesystem|file] ... ]

DESCRIPTION

       The command displays the amount of free disk space available either on the specified filesystem for example) or on the file system in which
       the specified file (such as is contained.  If no file system is specified, the free space on all of the normally mounted  file  systems	is
       printed.  The reported numbers are in kilobytes.

   Options
       The command recognizes the following options:

	      Display information regarding file system swapping.

	      Report the number of used and free inodes.

	      Display information for local file systems only (for example,
			     HFS and CDFS file systems).

	      Do not sync the file system data on the disk before reporting the usage.
			     Note that the data reported by may not be up to date.

	      Report on the file systems of a given
			     type (for example, or

RETURN VALUE

       The  command  returns  0  on success (able to get status on all file systems), or returns 1 on failure (unable to get status on one or more
       file systems).

WARNINGS

       If file system names are too long, the output for a given entry is displayed on two lines.

       The command does not account for any disk space reserved for swap space, or used for the HFS boot block (8 KB,  1  per  file  system),  HFS
       superblocks (8 KB each, 1 per disk cylinder), HFS cylinder group blocks (1 KB - 8 KB each, 1 per cylinder group), and inodes (currently 128
       bytes reserved for each inode).	Non-HFS file systems may have other items not accounted for by this command.

NAME

       df - report number of free file system disk blocks

SYNOPSIS

       FStype] specific_options] [special|directory]...

DESCRIPTION

       The  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 are path names, reports on the file systems containing the named files.  If the argument to is a special of an unmounted file
       system, the free space in the unmounted file system is displayed.

   Options
       recognizes the following options:

	      Report only the number of kilobytes (KB) free.

	      Report the number of files free.

	      Report only the actual count of the blocks in the free list
			     (free inodes are not reported).

	      Report only on the
			     FStype file system type (see fstyp(1M)).

	      Report the entire structure described in
			     statvfs(2).

	      Report the total number of inodes,
			     the number of free inodes, number of used inodes, and the percentage of inodes in use.

	      Report the allocation in kilobytes (KB).

	      Report on local file systems only.

	      Report the file system name.
			     If used with no other options, display a list of mounted file system types.

	      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.

	      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.

	      Do not sync the file system data on the disk before
			     reporting the usage.  Note that the data reported by may not be up to date.

	      Report the total allocated block figures and the number of free blocks.

	      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.

	      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  This
			     option allows the user to verify the command line.
