NAME

du - estimate file space usage


SYNOPSIS
du [OPTION]... [FILE]...


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 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


-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


-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 filesystems


-X FILE, --exclude-from=FILE
Exclude files that match any pattern in FILE.


--exclude=PATTERN Exclude files that match PATTERN.


--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


-m like --block-size=1M [deprecated]


--help display this help and exit


--version
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.


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).
