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 use SIZE-byte blocks

       -b, --bytes
     equivalent to ‘--apparent-size --block-size=1’

       -c, --total
     produce a grand total

       -D, --dereference-args
     dereference FILEs that are symbolic links

       --files0-from=F
     summarize disk usage of the NUL-terminated file names specified
     in file F

       -H     like --si, but also evokes a warning; will  soon change to  be
     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 FILE, --exclude-from=FILE
     Exclude files that match any pattern in FILE.

       --exclude=PATTERN Exclude files that match PATTERN.

       --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

       SIZE may be (or may be an integer optionally followed by) one  of  fol-
       lowing: 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).
