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,... (pow-
       ers 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).
