- This documentation is no longer being maintained and may be
- inaccurate or incomplete. The Texinfo documentation is now
- the authoritative source.
-
- This manual page documents the GNU version of ddddffff. ddddffff
- 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 containing a mounted filesystem, ddddffff shows the space
- available on that filesystem rather than on the filesystem
- containing the device node (which is always the root
- filesystem). This version of ddddffff cannot show the space
- available on unmounted filesystems, because on most kinds of
- systems doing so requires very nonportable intimate
- knowledge of filesystem structures.

- -_a, --_a_l_l
- Include in the listing filesystems that have 0 blocks,
- which are omitted by default. Such filesystems are
- typically special-purpose pseudo-filesystems, such as
- automounter entries. On some systems, filesystems of
- type ``ignore'' or ``auto'' are also omitted by default
- and included in the listing by this option.
-
- -_i, --_i_n_o_d_e_s
- List inode usage information instead of block usage.
- An inode (short for ``index node'') is a special kind
- of disk block that contains information about a file,
- such as its owner, permissions, timestamps, and
- location on the disk.
-
- -_k, --_k_i_l_o_b_y_t_e_s
- Print sizes in 1K blocks instead of 512-byte blocks.
- This overrides the environment variable
- POSIXLY_CORRECT.

-
- -_P, --_p_o_r_t_a_b_i_l_i_t_y
- Use the POSIX output format. This is like the default
- format except that the information about each
- filesystem is always printed on exactly one line; a
- mount device is never put on a line by itself. This
- means that if the mount device name is more than 20
- characters long (as for some network mounts), the
- columns are misaligned.
-
- -_T, --_p_r_i_n_t-_t_y_p_e
- Print a type string for each filesystem. Any such
- printed filesystem type name may be used as an argument
- to either of the --type= or --exclude-type= options.
-
- -_t, --_t_y_p_e=_f_s_t_y_p_e
- Limit the listing to filesystems of type _f_s_t_y_p_e.
- Multiple filesystem types can be shown by giving
- multiple -_t options. By default, all filesystem types
- are listed.
-
- -_x, --_e_x_c_l_u_d_e-_t_y_p_e=_f_s_t_y_p_e
- Limit the listing to filesystems not of type _f_s_t_y_p_e.
- Multiple filesystem types can be eliminated by giving
- multiple -_x options. By default, all filesystem types
- are listed.
-
- -_v Ignored; for compatibility with System V versions of
- ddddffff.
-
- --_h_e_l_p
- Print a usage message on standard output and exit
- successfully.
-
- --_v_e_r_s_i_o_n
- Print version information on standard output then exit
- successfully.
