Options:
  --help                show this help message
  -v, --version         show version
  -a, --all             include filesystems having 0 blocks
  -h, --human-readable  print sizes in human readable format (e.g., 1K 234M
                        2G)
  -H, --si              likewise, but use powers of 1000 not 1024
  -b BLOCKSIZE, --block-size=BLOCKSIZE
                        use BLOCKSIZE-byte blocks
  -l, --local           limit listing to local filesystems
  -k, --kilobytes       like --block-size=1024
  -m, --megabytes       like --block-size=1048576
  -g, --gigabytes       like --block-size=1073741824
  --blocks              use filesystem native block size
  --bw                  do not use colours
  --mounts=MOUNTS_FILE  File to get mount information from. On normal Linux
                        systems only /etc/mtab or /proc/mounts make sense.
                        Some other Unices use /etc/mnttab. Use /proc/mounts
                        when /etc/mtab is corrupted or inaccessible  (the
                        output looks a bit weird in this case).
  -B, --show-binds      show 'mount --bind' mounts
  -i, --inodes          show inode instead of block usage
