du - estimate file space usage
du [OPTION]... [FILE]...
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.
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).
