dfilemaker [OPTION] PATH...
dfilemaker is a tool for generating files and file trees which contain files suitable for testing.
NOTE: I cannot find these options in the code. I am not sure that they actually exist? Unless there is another version of the code somewhere?
.. option:: -d, --depth=*min*-*max*
Specify the depth of the file system tree to generate. The depth
will be selected at random within the bounds of min and max. The
default depth is set to 10 min, 20 max.
.. option:: -f, --fill=*type*
Specify the fill pattern of the file. Current options available are:
``random``, ``true``, ``false``, and ``alternate``. ``random`` will
fill the file using :manpage:`urandom(4)`. ``true`` will fill the file
with a 0xFF pattern. ``false`` will fill the file with a 0x00 pattern.
``alternate`` will fill the file with a 0xAA pattern. The default
fill is ``random``.
.. option:: -r, --ratio=*min*-*max*
Specify the ratio of files to directories as a percentage. The ratio
will be chosen at random within the bounds of min and max. The
default ratio is 5% min to 20% max.
.. option:: -i, --seed=*integer*
Specify the seed to use for random number generation. This can be
used to create reproducible test runs. The default is to generate a
random seed.
.. option:: -s, --size=*min*-*max*
Specify the file sizes to generate. The file size will be chosen at
random random within the bounds of min and max. The default file
size is set from 1MB to 5MB.
.. option:: -w, --width=*min*-*max*
Specify the width of the file system tree to generate. The width
will be selected at random within the bounds of min and max. The
width of the tree is determined by counting directories. The default
width is set to 10 min, 20 max.
.. option:: -h, --help
Print a brief message listing the *dfilemaker(1)* options and usage.
.. option:: -v, --version
Print version information and exit.
