NAME

   du - estimate file space usage

SYNOPSIS

   du [OPTION]... [FILE]...
   du [OPTION]... --files0-from=F

DESCRIPTION

   Summarize disk usage of the set of FILEs, recursively for directories.

   Mandatory  arguments  to  long  options are mandatory for short options
   too.

   -0, --null
          end each output line with NUL, not 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
   environment  variables.  Otherwise, units default to 1024 bytes (or 512
   if POSIXLY_CORRECT is set).

   The SIZE argument is an integer and  optional  unit  (example:  10K  is
   10*1024).   Units  are  K,M,G,T,P,E,Z,Y  (powers  of 1024) or KB,MB,...
   (powers 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).
