Description

In some file systems, calling du shows an invalid amount of occupied filespace. The solution is to call du with the option --apparent-size

Cons: With this option du shows a slightly smaller size than the files can actually take up, because only the net sum of the file sizes is counted without taking into account the hit to the cluster size.
