NAME
       du - estimate file space usage
SYNOPSIS
       du [OPTION]... [FILE]...
       du [OPTION]... --files0-from=F
DESCRIPTION
       Summarize disk usage of each FILE, recursively for directories.
       Mandatory  arguments  to  long  options are mandatory for short options
       too.
       -0, --null
              end each output line with 0 byte rather than newline
       -a, --all
              write counts for all files, not just directories
       --apparent-size
              print apparent sizes,  rather  than  disk  usage;  although  the
              apparent  size is usually smaller, it may be larger due to holes
              in ('sparse') files, internal  fragmentation,  indirect  blocks,
              and the like
       -B, --block-size=SIZE
              scale  sizes  by  SIZE  before printing them; e.g., '-BM' prints
              sizes in units of 1,048,576 bytes; see SIZE format below
       -b, --bytes
              equivalent to '--apparent-size --block-size=1'
       -c, --total
              produce a grand total
       -D, --dereference-args
              dereference only symlinks that are listed on the command line
       -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
       --files0-from=F
              summarize disk usage of the NUL-terminated file names  specified
              in file F; if F is -, then read names from standard input
       -H     equivalent to --dereference-args (-D)
       -h, --human-readable
              print sizes in human readable format (e.g., 1K 234M 2G)
       --inodes
              list inode usage information instead of block usage
       -k     like --block-size=1K
       -L, --dereference
              dereference all symbolic links
       -l, --count-links
              count sizes many times if hard linked
       -m     like --block-size=1M
       -P, --no-dereference
              don't follow any symbolic links (this is the default)
       -S, --separate-dirs
              for directories do not include size of subdirectories
       --si   like -h, but use powers of 1000 not 1024
       -s, --summarize
              display only a total for each argument
       -t, --threshold=SIZE
              exclude  entries  smaller  than  SIZE  if  positive,  or entries
              greater than SIZE if negative
       --time show time of the last modification of any file in the directory,
              or any of its subdirectories
       --time=WORD
              show  time  as WORD instead of modification time: atime, access,
              use, ctime or status
       --time-style=STYLE
              show times using STYLE, which can be: full-iso,  long-iso,  iso,
              or +FORMAT; FORMAT is interpreted like in 'date'
       -X, --exclude-from=FILE
              exclude files that match any pattern in FILE
       --exclude=PATTERN
              exclude files that match PATTERN
       -x, --one-file-system
              skip directories on different file systems
       --help display this help and exit
       --version
              output version information and exit
       Display   values  are  in  units  of  the  first  available  SIZE  from
       --block-size, and the DU_BLOCK_SIZE, BLOCK_SIZE and BLOCKSIZE  environ-
       ment  variables.   Otherwise,  units  default  to 1024 bytes (or 512 if
       POSIXLY_CORRECT is set).
       SIZE is an integer and optional unit (example:  10M  is  10*1024*1024).
       Units  are K, M, G, T, P, E, Z, Y (powers of 1024) or KB, MB, ... (pow-
       ers of 1000).

PATTERNS
       PATTERN  is  a shell pattern (not a regular expression).  The pattern ?
       matches any one character, whereas * matches any  string  (composed  of
       zero,  one  or  multiple  characters).  For example, *.o will match any
       files whose names end in .o.  Therefore, the command
              du --exclude='*.o'
       will skip all files and subdirectories ending in .o (including the file
       .o itself).
