Most of mfstools use following options to select format of printed numbers:

Print exact numbers (e.g. 1024).

Print numbers with binary prefixes (Ki, Mi, Gi as 2^10, 2^20 etc.).

Print numbers with SI prefixes (k, M, G as 10^3, 10^6 etc.).

The same can be achieved by setting MFSHRFORMAT environment variable to: 0 (exact
numbers), 1 or h (binary prefixes), 2 or H (SI prefixes), 3 or h+ (exact numbers and
binary prefixes), 4 or H+ (exact numbers and SI prefixes). The default is to print just
exact numbers.

Other options:

This option enables recursive mode.


When new object is created in LizardFS, attributes such as goal, trashtime and extra
attributes are inherited from parent directory. So if you set i.e. "noowner" attribute and
goal to 3 in a directory then every new object created in this directory will have goal
set to 3 and "noowner" flag set. A newly created object inherits always the current set of
its parent’s attributes. Changing a directory attribute does not affect its already
created children. To change an attribute for a directory and all of its children use '-r'
