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=aq*.oaq

will skip all files and subdirectories ending in .o (including the file .o itself).
