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).
