Thanks for your reply. I've read the thread and understand that the intended behavior is not to double-count nodes so we can get an accurate feel of the total size of the output of du -s by summing the sizes together. However, the behavior contrasts with the description of -s ("display only a total for each argument" on my system), so perhaps the documentation should be updated? While it may be intuitive not to double-count a given directory, I don't think the current description of -s makes it clear that the size reported for a directory might be greater than 0 but less than the actual size of the directory and all its contents (i.e. in the case where one of its subdirectory was counted earlier). It should be made clear that the numbers before each directory may in fact NOT be the actual size of each directory, because that's what the description for -s seems to say now.
