I'm trying to use du to investigate disk usage in a directory like so:du -hd1 | sort -rhThis gives me a list that starts as follows61G     .7.9G    ./A5.1G    ./B2.7G    ./.C1.6G    ./.D1.2G    ./.E1.2G    ./F850M    ./.G724M    ./H666M    ./I281M    ./J249M    ./.K150M    ./.LThe rest of the list sums up to less than 1GB and there are no large files directly contained in that directory:  ls -Slhtotal 1.8M...What is the source of the discrepancy between the total 61GB and the sum of less than 25GB of the directory sums?
Why do du's subdirectory values not sum up to total?
