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.

       -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

       --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)

       --si   like -h, but use powers of 1000 not 1024

       -k     like --block-size=1K

       -l, --count-links
              count sizes many times if hard linked

       -m     like --block-size=1M

       -L, --dereference
              dereference all symbolic links

       -P, --no-dereference
              don't follow any symbolic links (this is the default)

       -0, --null
              end each output line with 0 byte rather than newline

       -S, --separate-dirs
              do not include size of subdirectories

       -s, --summarize
              display only a total for each argument

       -x, --one-file-system
              skip directories on different file systems

       -X, --exclude-from=FILE
              exclude files that match any pattern in FILE

       --exclude=PATTERN
              exclude files that match PATTERN

       -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

       --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 STYLE: full-iso, long-iso, iso, +FORMAT FORMAT is interpreted like `date'

       --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).

       SIZE may be (or may be an integer optionally followed by) one of following: KB 1000, K 1024, MB 1000*1000, M 1024*1024, and so  on  for
       G, T, P, E, Z, Y.

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).
