du - Summarize disk usage of the set of FILEs, recursively for directories.
  -d, --max-depth=N     print the total for a directory (or file, with --all)
                          only if it is N or fewer levels below the command
                          line argument;  --max-depth=0 is the same as
                          --summarize
  -h, --human-readable  print sizes in human readable format (e.g., 1K 234M 2G)
  -x, --one-file-system    skip directories on different file systems
