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
-B, --block-size=SIZE use SIZE-byte blocks
-b, --bytes
print size in bytes
-c, --total
produce a grand total
-D, --dereference-args
dereference FILEs that are symbolic links
-h, --human-readable
print sizes in human readable format (e.g., 1K 234M 2G)
-H, --si
likewise, 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
-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
--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 following: kB 1000, K 1024, MB 1,000,000, M 1,048,576, 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).
