du - estimate file space usage

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

Summarize disk usage of each FILE, recursively for directories.

Mandatory arguments to long options are mandatory for short options

-a, --all
write counts for all files, not just directories

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

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 files that match PATTERN.

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

show time as WORD instead of modification time: atime, access,
use, ctime or status

show times using style STYLE: full-iso, long-iso, iso, +FORMAT
FORMAT is interpreted like `date'

--help display this help and exit

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.

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).
