Print raw numbers in bytes.
-b|--raw
raw numbers in bytes, without the *B* suffix
-t <treeid>
Print stats only for the given treeid.
--human-readable
print human friendly numbers, base 1024, this is the default
--iec
select the 1024 base for the following options, according to the IEC standard
--si
select the 1000 base for the following options, according to the SI standard
