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 environ-
       ment 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).
