NAME         top

       du - estimate file space usage

SYNOPSIS         top

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

DESCRIPTION         top

       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).  Binary prefixes can be used, too:
       KiB=K, MiB=M, and so on.

PATTERNS         top

       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).
