- This manual page documents the GNU version of ddddffff. ddddffff
- displays the amount of disk space available on the filesys-
- tem containing each argument pathname. If no pathnames are
- given, the space available on all currently mounted filesys-
- tems 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 full pathname of a disk device node
- containing a mounted filesystem, ddddffff shows the space avail-
- able on that filesystem rather than on the filesystem con-
- taining the device node (which is always the root filesys-
- tem). 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 loca-
- tion 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 filesys-
- tem is always printed on exactly one line; a mount dev-
- ice 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, --_t_y_p_e=_f_s_t_y_p_e
- Limit the listing to filesystems of type _f_s_t_y_p_e. Mul-
- tiple 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 suc-
- cessfully.
-
- --_v_e_r_s_i_o_n
- Print version information on standard output then exit
- successfully.
